Hey dear here's ur answer..
Rate of change of velocity is acceleration. SI unit of acceleration is m/s^2
When body is increasing uniformly its positive acceleration...nd when body is decreasing uniformly its negative acceleration.
One example is a freely falling ball.
HOPE this helps u..

Hi..
Acceleration of a body is defined as the rate of change of it's velocity with time.
It's SI unit is metered per second square.
Acceleration is considered positive when it is moving with gravity and is considered negative when it is moving with gravity.
Ex:when a bicycle is moving down a slope and the rider is not pedaling (wind resistance can be neglected).
