Explanation:
A bicycle or car will keep moving unless the rider or driver applies a frictional force through the brakes to stop it. A driver or passenger in a moving car who is not wearing a seat belt will be thrown forward when the car suddenly stops because he remains in motion
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
