Acceleration:
It is defined as rate of change of velocity.
● a=v-u/t
●It is a vector quantity.
●It's SI unit are: m/s^2
ACCELERATION are if two types:
1. POSITIVE acceleration
2.Negative acceleration.
POSITIVE acceleration:
If velocity of an object increases then it is said to have positive acceleration.
Example:
A train leaving a Railway station.

Negative acceleration:
If an object has decreases in its velocity then it is said to have negative acceleration or retardation.
Example: A train entering the railway station.
