State newton's first law of motion and give an example also

Newton's first law of motion is as follows:
A body continues to be in the state of rest or of uniform motion until an external unbalanced force acts on it. 
It is also known as the law of inertia. Inertia is the property owing to the mass of a body which expresses a body's unwillingness to change its state of motion or rest.
For ex:
A moving car comes to rest only by applying brakes.
A satellite or any foreign body keeps on moving in outer space until external force is applied to stop it.
