Answer»

a) Acceleration is defined as the rate of change in a body’s velocity with respect to time. SI unit of acceleration is m/s2. 

b) A body is said to have a uniform acceleration when it travels in a straight line with its velocity increasing at equal intervals of time. Motion of a free falling ball is an example of uniform acceleration.
