Question

define velocity and acceleration its si unit​

Answer 1

Explanation:

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

Answer:

Acceleration can be defined as the rate of change of velocity with time. The S.I. unit of acceleration is meter per second square or ms−2.

Velocity is a vector quantity that refers to the rate at which an object changes its position.

The SI unit of velocity is meter/second
