Kinetic energy

Kinetic energy is the energy an object has due to its motion. As long as an object is moving at the same velocity, it will maintain the same kinetic energy.

The kinetic energy of an object is calculated from the velocity and the mass of the object. As you can see from the equation below, the velocity is squared and can have a significant impact on the kinetic energy.

Here is the equation for calculating kinetic energy (KE):
 

KE    =     ½*m*v²

where m =…
