Newton's Second Law of Motion
Calculate force using Newton's Second Law: Force equals mass times acceleration. This fundamental physics equation describes how objects respond to forces.
Force Formula
F = m × a
F = Force (Newtons), m = mass (kg), a = acceleration (m/s²). Weight = mass × gravity (9.8 m/s²).
Frequently Asked Questions
What is a Newton?
A Newton (N) is the SI unit of force. 1 N = force needed to accelerate 1 kg at 1 m/s². Your weight in Newtons = mass × 9.8.
What is the difference between mass and weight?
Mass is amount of matter (constant). Weight is force of gravity on mass (varies by location). Weight = mass × g.
