## Simple Pendulum Motion

Simple pendulum can be defined as the heavy metallic bob attached with a inextensible, flexible string of negligible mass fixed at one end so that it can freely vibrate (oscillate) about a fixed position.

## A fan makes 10 revolutions in 3 second which is just switched on. Considering uniform acceleration the number of revolution made by the fan in next 3 seconds is

## Oscillation of spring

Oscillation of spring with loaded mass executes simple harmonic motion. One end of a spring is attached to support and the other end is attached with some mass. When the mass is extended by a certain displacement and is released, it begins to execute about a mean position due to restoring force in

## A circular disk rolls down an inclined plane. The fraction of its total energy associated with its rotational motion is

## Kinetic enrgy and Potential energy in simple harmonic motion

Kinetic energy and potential energy in simple harmonic motion change with time agrfnd position but the overall energy (i.e. sum of K.E and P.E) remain constant throughout the time and position.

## Simple Harmonic Motion

Simple harmonic motion (commonly known as SHM) is a type of oscillatory motion where acceleration produced on a particle or body is directly proportional to the displacement by the particle or body and is directed towards a mean position.

## Kinetic Energy and acceleration of a rolling body

The rolling body in an inclined plane has both rotational as well as translational motion as the body rotates as well as travels some distance in a straight line. The total kinetic energy of a rolling body can be found by adding its translational as well as rotational kinetic energy.

## Angular Momentum

Angular momentum is the moment of linear momentum. It defines the quantity of motion of rigid rotational bodies. Angular momentum is defined as the vector product( or cross product) of distance from the axis of rotation with the linear momentum

## Work done by couple

Consider a wheel of radius ‘r’ rotating about an axis through a center due to the application of a couple of magnitude ‘F’ at points A and B.
