# Kinetic Energy

Written by Jerry Ratzlaff on . Posted in Kinematics

Kinetic energy, abbreviated as KE, is the energy an object possesses by virtue of its motion.  If it moves, it has kinetic energy.

## Kinetic energy formula

 $$\large{ KE = \frac{1}{2} \; m \; v^2 }$$

### Where:

 Units English SI $$\large{ KE }$$ = kinetic energy $$\large{ ft-lbf }$$ $$\large{J}$$ $$\large{ m }$$ = mass $$\large{lbm}$$ $$\large{kg}$$ $$\large{ v }$$ = velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
