Kinetic energy is also known as the energy of motion. The opposite of kinetic energy is potential energy. The kinetic energy of an object is the energy that the object possesses because it is in motion. In order for something to have kinetic energy, you must "do work" on it–push or p...

Kinetic Energy Kinetic energy is energy of motion. Objects that are moving, such as a roller coaster, have kinetic energy (KE). If a car crashes into a wall at 5 mph, it shouldn't do much damage to the car. But if it hits the wall at 40 mph, the car will most likely be ...
Heat tends to "move" from warmer to cooler areas, that is, into regions into which there is presently less heat. While heat cannot be held or seen, changes in its magnitude can be measured via changes in temperature. Temperature is a measure of the average kinetic energy of a set of mo...
