Motion

The harmonic oscillations of a physical system results from two basic properties namely elasticity and inertia. Let consider a body displaced from a mean position.…

Simple harmonic motion can also be angular. In this case, the restoring torque required for producing SHM is directly proportional to the angular displacement and…

Graphical representation of Simple Harmonic Motion: Graphical representation of displacement, velocity and acceleration of a particle vibrating simple harmonically with respect to time t is…

Simple harmonic motion is a motion where a restoring force is functional that is comparative to the displacement and in the reverse direction of that…

Periodic Motion: Any motion that repeats itself after regular intervals of time is known as periodic motion. Any motion that repeats itself at a normal interval…

Kepler’s laws of planetary motion (i) The law of orbits Each planet moves in an elliptical orbit with the Sun at one focus. A is…

The law of conservation of angular momentum states that when no external torque acts on an object, no change of angular momentum will occur. Angular…

The angular momentum of a rotating rigid body is, L = I ω The torque acting on a rigid body is, τ = dL/dt When…

Let consider a system of n particles of masses m1, m2 … …mn situated at distances r1, r2 … …r3 respectively from the axis of…

The angular momentum in rotational motion is similar to the linear momentum in translators’ motion. The linear momentum of a particle moving along a straight…
