Etymology
From Greek kinetikos 'of motion', from kinein 'to move', plus energeia 'activity'.
Full origin of kinetic energy →Frequently asked questions
What is the difference between kinetic and potential energy?
Kinetic energy is energy of motion, so an object only has it while it is moving. Potential energy is stored energy an object has because of its position or condition, such as a book on a high shelf or a stretched spring. A falling object converts potential energy into kinetic energy as it drops.
What is the formula for kinetic energy?
KE equals one half times mass times velocity squared, written KE = ½mv². Mass is in kilograms and velocity in metres per second, giving an answer in joules.
Why does doubling speed quadruple kinetic energy?
Because velocity is squared in the formula, so multiplying speed by two multiplies the energy by two squared, which is four. This is why stopping distances grow so sharply with speed.
