Three laws of motion

The three laws of motion, formulated by Sir Isaac Newton, describe how objects move: 1. **Inertia**: An object at rest stays at rest, and an object in motion remains in motion at a constant speed and direction, unless acted upon by an outside force. 2. **Acceleration**: The acceleration of an object depends on the net force acting on it and its mass; more force means more acceleration, and heavier objects accelerate less for the same force. 3. **Action and Reaction**: For every action, there is an equal and opposite reaction; when one object pushes or pulls another, both experience equal force in opposite directions.
