Acceleration

Acceleration is explained with example.

The rate at which object changes its velocity is known as acceleration. It is a vector quantity.

It is detonated by a.

a = velocity/time

Its unit = m/s2

When an object changes its velocity by equal amount in every one second is called constant acceleration.

Eg:-

A car cover reaches its destination in 120 sec. with the velocity of 60 m/s. Find its acceleration.

Ans-

Time taken by car = 120 sec.

Velocity of the car = 60 m/s

Acceleration of the car =  velocity/time

= 60/120

=0.5 m/s2
