How it's calculated
F = m × a (Newton's second law)
Common questions
What is 1 Newton?
One Newton is the force needed to accelerate 1 kg at 1 m/s². It's roughly the weight of a small apple on Earth.
How do force and weight differ?
Weight is a specific force: mass × gravitational acceleration. On Earth's surface, g ≈ 9.81 m/s², so a 10 kg mass weighs 98.1 N.
