Newton's Second Law

Force equals mass times acceleration.

Formula

F=maF = ma

Variables

FForce (N)
mMass (kg)
aAcceleration (m/s²)

Example

A 2 kg cart pushed with 10 N accelerates at a = 10/2 = 5 m/s².

Did You Know?

F = ma is the equation on which all of classical mechanics is built — Newton wrote it in his 1687 Principia.
