What is physics?

Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity .

Physicists and other scientists use the International System of Units (SI) in their work because they wish to use a system that is agreed upon by scientists worldwide. Since 2019 the SI units have been defined in terms of fundamental physical constants, which means that scientists anywhere using SI can agree upon the units they use to measure physical phenomena.

physics , science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe . In the broadest sense, physics (from the Greek physikos ) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels. Its scope of study encompasses not only the behaviour of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields. Its ultimate objective is the formulation of a few comprehensive principles that bring together and explain all such disparate phenomena.

(Read Einstein’s 1926 Britannica essay on space-time.)

Physics is the basic physical science . Until rather recent times physics and natural philosophy were used interchangeably for the science whose aim is the discovery and formulation of the fundamental laws of nature. As the modern sciences developed and became increasingly specialized, physics came to denote that part of physical science not included in astronomy , chemistry , geology , and engineering . Physics plays an important role in all the natural sciences, however, and all such fields have branches in which physical laws and measurements receive special emphasis, bearing such names as astrophysics , geophysics , biophysics , and even psychophysics . Physics can, at base, be defined as the science of matter , motion , and energy . Its laws are typically expressed with economy and precision in the language of mathematics .

Both experiment, the observation of phenomena under conditions that are controlled as precisely as possible, and theory, the formulation of a unified conceptual framework, play essential and complementary roles in the advancement of physics. Physical experiments result in measurements, which are compared with the outcome predicted by theory. A theory that reliably predicts the results of experiments to which it is applicable is said to embody a law of physics. However, a law is always subject to modification, replacement, or restriction to a more limited domain, if a later experiment makes it necessary.

The ultimate aim of physics is to find a unified set of laws governing matter, motion, and energy at small (microscopic) subatomic distances, at the human (macroscopic) scale of everyday life, and out to the largest distances (e.g., those on the extragalactic scale). This ambitious goal has been realized to a notable extent. Although a completely unified theory of physical phenomena has not yet been achieved (and possibly never will be), a remarkably small set of fundamental physical laws appears able to account for all known phenomena. The body of physics developed up to about the turn of the 20th century, known as classical physics, can largely account for the motions of macroscopic objects that move slowly with respect to the speed of light and for such phenomena as heat , sound , electricity , magnetism , and light . The modern developments of relativity and quantum mechanics modify these laws insofar as they apply to higher speeds, very massive objects, and to the tiny elementary constituents of matter, such as electrons , protons , and neutrons .

The scope of physics

The traditionally organized branches or fields of classical and modern physics are delineated below.

Mechanics is generally taken to mean the study of the motion of objects (or their lack of motion) under the action of given forces. Classical mechanics is sometimes considered a branch of applied mathematics. It consists of kinematics , the description of motion, and dynamics , the study of the action of forces in producing either motion or static equilibrium (the latter constituting the science of statics ). The 20th-century subjects of quantum mechanics, crucial to treating the structure of matter, subatomic particles , superfluidity , superconductivity , neutron stars , and other major phenomena, and relativistic mechanics , important when speeds approach that of light, are forms of mechanics that will be discussed later in this section.

In classical mechanics the laws are initially formulated for point particles in which the dimensions, shapes, and other intrinsic properties of bodies are ignored. Thus in the first approximation even objects as large as Earth and the Sun are treated as pointlike—e.g., in calculating planetary orbital motion. In rigid-body dynamics , the extension of bodies and their mass distributions are considered as well, but they are imagined to be incapable of deformation . The mechanics of deformable solids is elasticity ; hydrostatics and hydrodynamics treat, respectively, fluids at rest and in motion.

The three laws of motion set forth by Isaac Newton form the foundation of classical mechanics, together with the recognition that forces are directed quantities ( vectors ) and combine accordingly. The first law, also called the law of inertia , states that, unless acted upon by an external force , an object at rest remains at rest, or if in motion, it continues to move in a straight line with constant speed . Uniform motion therefore does not require a cause. Accordingly, mechanics concentrates not on motion as such but on the change in the state of motion of an object that results from the net force acting upon it. Newton’s second law equates the net force on an object to the rate of change of its momentum, the latter being the product of the mass of a body and its velocity. Newton’s third law, that of action and reaction, states that when two particles interact, the forces each exerts on the other are equal in magnitude and opposite in direction. Taken together, these mechanical laws in principle permit the determination of the future motions of a set of particles, providing their state of motion is known at some instant, as well as the forces that act between them and upon them from the outside. From this deterministic character of the laws of classical mechanics, profound (and probably incorrect) philosophical conclusions have been drawn in the past and even applied to human history.

Lying at the most basic level of physics, the laws of mechanics are characterized by certain symmetry properties, as exemplified in the aforementioned symmetry between action and reaction forces. Other symmetries, such as the invariance (i.e., unchanging form) of the laws under reflections and rotations carried out in space , reversal of time, or transformation to a different part of space or to a different epoch of time, are present both in classical mechanics and in relativistic mechanics, and with certain restrictions, also in quantum mechanics. The symmetry properties of the theory can be shown to have as mathematical consequences basic principles known as conservation laws , which assert the constancy in time of the values of certain physical quantities under prescribed conditions. The conserved quantities are the most important ones in physics; included among them are mass and energy (in relativity theory, mass and energy are equivalent and are conserved together), momentum , angular momentum , and electric charge .

• Introduction to physics

What is physics?

• Preparing to study physics

• Precisely define the most fundamental measurable quantities in the universe (e.g., velocity, electric field, kinetic energy). The effort to find the most fundamental description of the universe is a quest that has historically always been a big part of physics, as can be seen in the comic image below. What does fundamental mean? There are some measurable quantities that are not considered fundamental, like the population of Ireland or the value of the stock exchange. Even though those quantities are measurable, and theoretically might be describable using an unthinkably complex application of the fundamental laws of physics, we would not typically consider theories about such things to be physics. Exactly where the line is drawn between fundamental and not fundamental is a little vague and shifts with history. A rough guide is that if you were to reply with the word “why?” over and over to whatever explanation a professor were giving you, the last and best scientific answer he or she would give you is most likely to be a law of physics, assuming they don't throw you out of their office before that point.
• Find relationships between those fundamental measured quantities (e.g., Newton’s Laws, conservation of energy, special relativity). These patterns and correlations are expressed using words, equations, graphs, charts, diagrams, models, and any other means that allow us to express a relationship in a way that we as humans can better understand and use. Math makes things simpler?! Believe it or not, the principles, graphs, laws, and equations used in physics were not created to make explaining the universe more difficult; they are there to make it easier to explain the universe and precisely illustrate the patterns found within it. This might serve as little solace to a physics student struggling with a seemingly random and unrelated set of equations and definitions, but try to remember that underneath all of the intimidating and sometimes foreign-looking mathematical symbols, there is usually a simple conceptual idea. The math simply makes it possible to formulate a conceptual idea in a very precise and concise manner.

Physics (Essay) Paper 2 WASSCE (SC), 2017

• Subject Home

General Comments

The standard of the paper was comparable to previous years in terms of the demands of the questions, the level of thinking and the concepts tested. The paper tested candidates understanding of basic physics principles, laws and theories. It also tested candidates’ ability to handle simple numerical problems.

The questions were straight to the point and required short answers as to show thorough understanding of the subject matter. The paper despite the limited questions required, spread across the syllabus with respect to recall of concepts, comprehension and the application of such concepts in solving numerical problems. The marking scheme was comprehensive, specific and less ambiguous. Candidates’ performance was lower as compared to previous years.

The time allotted for the paper was adequate. The performance of the candidates was lower than WASSCE for School Candidates 2016. This year paper recorded candidature of 704504 with raw mean score of 15 out of 60 and standard deviation of 08.43 as compared to WASSCE for School Candidates 2016 with a raw mean score of 19 out of 60 and standard deviation of 08.83 with candidature of 666992.

(ii)They are use to find dimensions of physical constants or coefficients.

(iii)They are use to convert a physical quantity from one system of units to another.

Time of flight: Time of flight (T) is the time required for a projectile to return to the Same level from which it was projected

T= 2usin θ / g

Maximum height: Maximum height(H) is the highest vertical distance attained as measured from the horizontal projectile plane.

H = U²sin²θ / 2g

Range : Range(R) is defined as the horizontal distance from the point of projection to the point where the projectile hits the projection plane again

R= U²sin2θ / g

No (7a) Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons.

(5b) (i) free electrons which have negative charges (ii) holes, which have positive charges

(i)by heating past the Curie point

(ii)by applying a strong magnetic field

ANSWER 3 ONLY.

Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. … Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

The lower fixed point, or ice point, is the temperature of pure melting ice at normal atmospheric pressure. While The upper fixed point, is the temperature of pure boiling water at normal atmospheric pressure.

 9c. Linear expansivity is the fractional increase in length of a specimen of a solid, per unit rise in temperature. If a specimen increases in length from l1 to l2 when its temperature is raised θ°, then the expansivity (α) is given by l2 = l1(1 + αθ).*PHYSICS* 

(10bi) The principle of superposition says: When two or more waves cross at a point, the displacement at that point is equal to the sum of the displacements of the individual waves. The individual wave displacements may be positive or negative. If the displacements are vectors, then the sum is calculated by vector addition.

(10c) Refraction depends on the wavelength. As blue light has shorter wavelength moving from air to glass than red so it refract more than red.

No (11ai) Reactance is the opposition of a circuit element to the flow of current due to that element’s inductance or capacitance.

(11aii) Impedance is measure of the opposition to the flow of alternating current through a circuit

(8ai) Work is said to be done whenever a force moves a body through a certain distance in the direction of force and is equal to the product of the force and the distance moved.

(8aii) Workdone = Force * distance = F*S F = m(v/t) Workdone = m(v/t) * 1/2vt = 1/2mv² Ek = 1/2mv² ie workdone = change in kinetic energy of the body

(8bi) Kinetic friction is the force that must be overcome so that a body can move with uniform speed over another body

(8bii) (i)Nature of surfaces in contact (ii)Depends on the normal force pressing the surfaces together

(8ci) Tc – umg = ma Tc – (0.3 * 3* 10)= 3*2 Tc – 9 = 6 Tc = 9+6 = 15N

(8cii) TB – 2umg = ma TB – 2(9)= 3*2 TB = 6+18 TB = 24N

(8ciii) TA – 3umg = ma TA – 3(9) = 3*2 TA – 27 = 6 TA = 6+27 TA = 33N

• Problem of the Week

During each week from 2002 to 2004, I posted a problem on this page. Some problems are new, and some are classics. Half of them are physics (the odd weeks), and half are math (the even weeks). In most cases they're quite difficult. After all, I call them "Problems of the Week," and not "Problems of the Hour"! Many of the math problems can be found in my book: The Green-Eyed Dragons and Other Mathematical Monsters . And many of the physics problems can be found in my classical mechanics textbook  for the Physics 16 course here at Harvard.
