Kinetic Energy Formula

Also known as: KE Formula

KE = \frac{1}{2}mv^2

KE = ½mv²

What It Calculates

The energy an object possesses due to its motion. Doubling the speed quadruples the kinetic energy.

Symbol	Name	Unit	Description
KE	Kinetic Energy	J (Joules)	Energy of motion
m	Mass	kg	Mass of the moving object
v	Velocity	m/s	Speed of the object

1KE = ½ × 1500 × 20²

2KE = 750 × 400 = 300,000 J = 300 kJ

Result: 300 kJ

Energy scales with v², so small speed increases have big energy impacts

Use consistent SI units (kg, m/s)

PE = m × g × h

W = F × d × cos(θ)

F = m × a
