Uniform velocity

Uniform velocity

A. body is said to move with uniform velocity if its rate of change of distance moved vith time in a specified direction is constant)

Acceleration

When the velocity of a body is changing, the body is said to be accelerating. celebration is defined as the rate of change of velocity with time. laceration is regarded as positive if the velocity is increasing, and negative if the ‘velocity is decreasing. Ordinarily, however, most people restrict the use of the word acceleration to cases of increasing velocity only, while a decreasing velocity or slow mg down is usually called a deceleration or retardation.
