PHYSICS PHYSICAL QUANTITIES VELOCITY[V] Displacement [d] is the shortest distance between the initial and final position of a body. Velocity of a moving body is the rate of change of displacement of the body in a particular direction and its unit is ms-1. Velocity is a measure of how fast the matter is moving or its rate of change of its position with time.it is given by the relation: V=d/t V=velocity D=displacement t=time in seconds magnitude of velocity is called speed which is a scalar quantity. ACCELERATION [a] Rate of change of velocity is called acceleration. its unit is ms-2. It is a measure of how quickly or slowly velocity is changing. velocity is constant acceleration is zero. a= [vf - v0]/t vf = final velocity v0 = initial velocity t = time interval
