Answer:
Acceleration
It is defined as the rate of change in velocity.
Mathematically;
a = v/t
SI unit of acceleration
Unit of velocity/Unit of time = m/s^2 = ms^-2
In physics or physical science
It is vector quantity
dimension ;
→ length/time².
In SI units, acceleration is measured in meters/second² using an accelerometer.
- When velocity or direction are changed, there is acceleration (or deceleration)
