Question

_____ is the rate of change in velocity.

Answer 1

Acceleration is the rate of change in velocity

Answer 2

Acceleration

Step-by-step explanation:

Acceleration is the rate of change in velocity. Mathematically, it is given by :

`a=(v-u)/(t)`

Where

v = final velocity of an object

u = initial velocity of an object

t = time taken

It can also be written in differentiating form as :

`a=(dv)/(dt)=(\Delta v)/(\Delta t)`

For an freely falling object, the value of acceleration is equal to g i.e. 9.8 m/s².
