Newton's Second Law: F = ma

Newton's Second Law of Motion states that the net force acting on an object equals its mass multiplied by its acceleration: F = m × a. Force is measured in Newtons (N), where 1 N = 1 kg × 1 m/s².

This equation is the basis for classical mechanics. From it, you can calculate any variable: mass = F/a, acceleration = F/m. If you know the force applied and the object's mass, you know exactly how it will accelerate.

Types of Force

Gravitational force (weight): F = m × g, where g ≈ 9.81 m/s² on Earth. A 70 kg person weighs 70 × 9.81 = 687 N. Normal force: The perpendicular force a surface exerts on an object resting on it. Friction: F = μ × N, where μ is the coefficient of friction and N is the normal force. Tension: Force transmitted through a rope or cable. Applied force: Any external force applied directly to an object.

Real-World Force Calculations

A car of 1,500 kg accelerating at 4 m/s² requires a net force of 6,000 N from the engine (after accounting for friction). A crane lifting a 2,000 kg load must exert at least 19,620 N (2,000 × 9.81) just to hold it steady, plus more to accelerate it upward. Sports: a baseball pitched at 90 mph accelerated over ~0.05 seconds from the pitcher's hand experiences roughly 200 N of force.
