The calculated energy is 200000 J. An item in motion has energy, which is called kinetic energy.

Motion in space you walk down the street, and the rotation of the planet around the sun are all examples of kinetic energy. is inversely proportional to the square of the object's velocity and its mass: K.E. = 1/2 m v2. Motion is created by kinetic energy. Any moving item uses kinetic energy, such as a person walking, a baseball being thrown, a piece of food falling from a table, or a charged particle in an electric field.

Energy Kinetic =.5 (m.v.v)

In this issue,

mass (m) = 1000 kg

The speed is 20 m/s.

So,

0.5 (1000 20 20 20) = 200000 J is the total kinetic energy.
