Question

difference between acceleration and retardation​

Answer 1

Answer:

See the explanation

Explanation:

Acceleration of a body is defined as the rate of change of its velocity with time. Velocity of the body increases with time. Retardation means negative acceleration. If the velocity of a body decreases,the acceleration is negative.

Answer 2

Acceleration is the increase in velocity per second , while retardation is the decrease in velocity per second . Thus, retardation is negative acceleration.

In general, Acceleration is taken as positive while retardation is taken as negative.
