Concepts

Momentum

Quantity of motion in a body because of its mass and velocity

Inertia

Inability of an object to change its state by itself

Force

Push of Pull action which changes the state of the object in rest or at uniform motion

Frequency

Number of revolutions per second

Time Period

Time taken to complete one revolution

Centripetal Acceleration

Acceleration directed along the radius of the circular path and towards its center

Angular Acceleration

Rate of change of angular speed of an object

Angular Speed

Rate of change of angular position with respect to time

Angular Displacement

The angle between the beginning and ending point of the motion of the object in a given time

Trajectory

Path taken by object when it is in projectile motion
