Question

define acceleration and write it's unit​

Answer 1

In physics or physical science, acceleration (symbol: a) is defined as the rate of change (or derivative with respect to time) of velocity. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second² using an accelerometer.

Answer 2

• Acceleration is defined as the rate of change of velocity.
• It is thus a vector quantity.dimension l/t².
• In SI units, acceleration is measured in m/s².

⚡[Where l = length, t = time, m = meter & s = second]
