What causes kinetic energy?

A collision of pool balls is an example of kinetic energy being transferred from one object to another. Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. read more

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. read more
