Question

What do you mean by acceleration? What is its 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 rate of change of velocity

it can be written as ∆v/∆t

and can also be as (v-u)/t

here v is equal to final velocity and u is equal to initial velocity

S.I unit of acceleration is metre per second square ms^2
