Question

_____ is the rate of change in velocity.

Answer 1

Acceleration is the rate of change in velocity

Answer 2

Answer:

Acceleration

Explanation:

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

$a=\dfrac{v-u}{t}$

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 :

$a=\dfrac{dv}{dt}=\dfrac{\Delta v}{\Delta t}$

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