Question

Describe the rate of change of velocity. ​

Answer 1

$\huge{\pink{\green {\sf\boxed{ANSWER}}}}$

Rate of change of velocity is called acceleration(a=dv/dt)

Answer 2

The displacement of an object , in unit interval of time , is called the velocity of the object.

We all know,

Velocity = Displacement / time

Velocity is represented by V.

Its unit mass = $ms^{-1}$.

Suppose the velocity of an moving object is v1 at t1 and becomes v2 at time t2.

The rate of change in velocity will be v2 - v1.
