Question

Different between acceleration and retardation. ​

Answer 1

Answer:

If the direction of both the 'rate of change of velocity' and velocity are same then the 'rate of change of velocity' is called acceleration. If the direction of 'rate of change of velocity' and velocity are opposite to each other then the 'rate of change of velocity' is called retardation.

Answer 2

Explanation:

in too easiest words....

• The Acceleration is defined as the "Rate of change of its velocity with time." or "Velocity of the body increases with time."

• i.e Acceleration = Change in velocity / Time taken for change

• ★Negative acceleration is called Retardation.

• if the velocity of the body decrease, the Acceleration will be negative.

Example:

The acceleration of a body is -5 m/s²

then, we can say that the retardation of the body will be 5 m/s².

i hope this may help you.
