Question

define acceleration, write its SI unit​

Answer 1

Answer:

Explanation:

Rate of change of velocity of an object  is acceleration .

It is repesented as  a=v/t  where a is acceleration ,

                                         v is velocity (m/sec)

                                          t is time (sec)

SI unit : m/s²

Answer 2

A n s w e r: -

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.

SI unit: m/s2, m·s−2, m s−2
