Kinetic Energy Calculator :

Enter the Kinetic energy calculator calculates the Mass in kilograms(kg), Velocity in (m/s), Kinetic energy in joules(J), and you get the calculation below the calculator check it.

Kinetic Energy Calculator

Kinetic Energy Formula :

kinetic energy K.E(J) in Joule is equal to the product of mass of the body m(kg) in kilogram is multiply by the velocity v2(m/s) in meter per second. Hence the kinetic energy formula has been written as,

K.E(J) = 1/ 2 m(kg) v2(m/s)

Where,

M → mass of the body in (kg)

V → velocity with which the body is travelling in (m/s)

The SI unit of kinetic energy is Joule (J) or (kg.m2.s-2)

Sample Problems :

Example 1:

Calculate the Kinetic energy? In a car is travelling at a velocity of 4 m/s and it has a mass of 150 Kg.

Solution :

Given that,

The mass of the vehicle, m = 150 kg,

The velocity of the vehicle, v = 4 m/s

The kinetic of the vehicle is,

K.E = 1/ 2 mv2

            = 1/2 * 150 kg* (4 m/s)2

= 1200 J

Hence, the kinetic energy of the vehicle is equal to 1200 J.

Example 2:

Calculate the Kinetic energy? In a car is travelling at a velocity of 10 m/s and it has a mass of 2 Kg.

Solution :

Given that,

The mass of the ball, m = 2 kg,

The velocity of the ball, v = 10 m/s.

The kinetic of the ball is,

K.E = 1/ 2 mv2

= 1/2 * 2 kg * (10 m/s)2

= 100 J.

Hence , the kinetic energy of the ball is equal to 100 J.
