For a body moving in a circular path, its angular velocity is the rate of change of measured in per second. The linear speed of a body moving in a circular path of radius r, is the angular velocity multiplied by the .
If a body is moving in a circular path, its acceleration is directed towards the and is known as acceleration. The force keeping the body moving is acting towards the centre and is called the centripetal .
According to Newton's Law of Gravitation, the force of attraction between any two bodies is proportional to the of their masses and inversely proportional to the square of their apart.
For a body in circular motion, the time taken for one complete orbit is called the time, T.
A satellite that remains in the same position above the earth's surface is said to be in orbit.
When a spring is stretched beyond its natural length, the force pulling it back is called the force and is proportional to the . This is known as Law.
A body is moving with harmonic motion if its acceleration is proportional to its distance from a fixed point on its path, and the acceleration is always at that point. A pendulum with a angle of swing undergoes simple harmonic motion. The periodic time of a particle undergoing simple harmonic motion is the time for one complete . The number of cycles occurring per second is known as its , which is measured in . The is the greatest displacement that the particle has from the equilibrium position.
When a particle is undergoing simple harmonic motion its acceleration is a when its displacement is a maximum.
