Theory & Formula
Newton's Laws & Force
Newton's laws of motion describe the relationship between forces and motion. These fundamental principles form the basis of classical mechanics.
Newton's Second Law
\(F = ma\)
Force equals mass times acceleration. This is the most commonly used equation in physics.
Weight
\(W = mg\)
Weight is the force due to gravity acting on a mass. On Earth, g ≈ 9.8 m/s².
Friction
\(f = \mu N\)
Friction opposes motion and is proportional to the normal force. The coefficient of friction (μ) depends on the surfaces in contact.
Example
A 10 kg object accelerates at 2 m/s². What force is required? F = ma = (10)(2) = 20 N
\(F = ma = (10)(2) = 20 \, \text{N}\)
