Physics

Newton Second Law of Motion

Calculate force from mass and acceleration.

F = m × a

Formula Explanation

The net force on an object equals its mass multiplied by acceleration.

Variables Explained

F = Net force in newtons; m = Mass in kilograms; a = Acceleration in m/s².

Solved Example

Find the force on a 5 kg object accelerating at 2 m/s².
F = 5 × 2 = 10 N.

Exam Tip

Use the net force and SI units.
