Laws of Motion — Science STD 9 — Question

Uniform circular motion: Displacement is zero :: Uniform velocity : Acceleration is zero

When body comes to rest at the end of the motion : Final velocity is zero :: When body is at rest at the starting of motion : Initial velocity is zero

Inertia : Newton’s 1st law :: Rate of change of momentum : Newton’s 2nd law

Speed zero: Body at rest :: Negative acceleration : Retardation

Displacement : Vector quantity :: Distance : Scalar quantity
