Question

what is acceleration and retardation?????????​

Answer 1

*****************************************************************

Acceleration of a body is defined as the rate of change of its velocity with respect to time.

si unit is m/s^2

ex: A car accelerate(+ 5m/s^2)

(positive sign denoting acceleration)

simple way meaning car speed increase

Retardation means negative acceleration. If the velocity of a body decreases,the acceleration is negative.

ex :A car retardation (-5m/s^2)

(negative sign means retardation )

simple way car speed decreases in retardation
