Kinetic Energy:


Define:

Kinetic energy is the energy an object has while in motion. It's a scalar quantity, meaning it's described by it's magnitude alone. An object with a mass of 100kg and a velocity of 100m/s has 500,000 joules of kinetic energy.

units: (base or derived)

Joules


Equation:

KE = kinetic energy

m = mass

v = velocity

KE = 1/2 * m * v ²


Unlike potential energy, kinetic energy is.........

Kinetic energy is the energy an object has while in motion, and potential energy is an object's stored energy due to it's position. An arrow in a drawn bow has potential energy. When the arrow is released and put into motion, it has kinetic energy.
