accelerationAcceleration(m/s²)9.81

How It Works

Newton's Second Law of Motion

Force equals the product of mass and acceleration.

Formula

F = m * a

The SI unit of force is the newton (N), equivalent to 1 kg * m/s².

Worked Example

Find the force on a 10 kg object accelerating at 9.81 m/s².

mass = 10acceleration = 9.81
  1. 01F = m * a
  2. 02F = 10 * 9.81
  3. 03F = 98.1 N
