Question

Define acceleration
Write its mathematical expression and SI unit

Answer 1

Acceleration is a vector quantity that is defined as a rate which an object changes in velocity .

Answer 2

Answer:

Acceleration is the rate of change of velocity of an object with respect to time, acceleration vector

quantities, the orientation of an object acceleration is given by the orientation of the net force acting on that object

mathematical expression-a=v2/r

SI unit= meters per second squared
