What is Newton’s First Law?
An object at rest will stay at rest unless acted on by an unbalanced force. An object in motion will stay in motion at the same speed and in the same direction unless acted on by an unbalanced force. Simplified, an object moving, will continue moving, unless something stops it. An object not moving, will stay not moving, until something moves it. This is also known as inertia.

How does this apply to wearing seat belts?
Newton's law states that an object will continue moving in the same direction at the same speed until stopped. So if you are in a car traveling 35 mph, you and the car are traveling at the same speed. If you are in the car and hit a wall, normally the seat belt would stop you with the car if it suddenly decelerated. However, if you are not buckled up, you will continue to move 35 mph towards the windshield. This is well illustrated by the following GIF:
