Question

Define acceleration in your own words.

Answer 1

HEY!!

_________________________

⏺️Rate of change of velocity is known as acceleration.

⏺️The unit of acceleration is metre per second square.

⏺️Acceleration is denoted by small a. The formula to find acceleration is equal to v minus u by t .

⏺️Acceleration can be positive negative or zero.

⏺️Positive acceleration is known as acceleration.

⏺️Negative acceleration is known as retardation.

⏺️Zero acceleration is known as 0.

Answer 2

Hii...

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

i.e. accn. = change in velocity/time taken

or, a = (v - u)/t

S.I. unit of acceleration is m/s^2.
