Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 47: The Special Theory of Relativity

The Principle of Relativity

The principle of relativity is the necessity that the equations defining the laws of physics have a similar form in all acceptable frames of reference. For example, in the framework of distinct relativity, the Maxwell equations have a similar form in all inertial frames of reference.

Energy and Momentum

The energy and momentum formulas are used to realize the case of elements like the photon that have zero mass. Therefore elements with zero mass always travel with velocity ‘c’. The energy and momentum formulas denote p/E = v/c2, and therefore p = E/c for zero-mass elements.

Twin Paradox

The twin paradox is an assumed experiment in special relativity including the same twins, one of whom makes a passage into space in a high-speed rocket and comes back home to calculate that the twin who continued on Earth has aged more.

Kinematics

Kinematics is a branch of physics and a portion of classical mechanics related to the geometrically possible motion of a body or system of bodies without thought of the forces included. For example, moving trains or moving water in a river.

Frequency

Frequency is the number of happenings of a reciting event per unit of time. It is also mentioned as temporal frequency, which underlines the difference to spatial frequency and angular frequency. Frequency is calculated in units of hertz (Hz) which is equivalent to one incidence of a repeating event per second.

Speed

Speed refers to the distance travelled per unit of time. It is how fast the body is moving. It is the scalar quantity that indicates the magnitude of the velocity vector. Speed does not have a direction. Higher will be the speed, faster will be the moving object.

Velocity

Velocity is described as a vector measurement of the rate and direction of motion. It is the speed at which a body moves in one direction.
