## Newton's Laws

**"Bodies will continue to move with a uniform velocity (which includes being stationary) unless acted on by a resultant force."**

This means that if a body changes speed or direction a **resultant** force must be acting on it.

**"Resultant force is equal to the rate of change of momentum."**

This forms the basis of Newton's equation, **F=ma.** This equation actually comes from the idea of momentum, which can be found in the **Principles of the conservation of momentum Learn-it.**

The direction of the acceleration is always in the same direction as the unbalanced force.

**"Every force has an equal and opposite force acting on another object."**

This can all sound difficult to understand, but let's look at the laws in a simple example.

**Putting all three laws together:**
