FIRST LAW: INERTIA
Newton's first law, also called the law of inertia, states that an object remains at rest or continues in uniform motion unless it is compelled to change by the action of an external force. The object’s tendency to remain at rest or maintain a constant speed is called inertia and its resistance to deviation from inertia varies with its mass. It takes a physical effort -- a force -- to overcome inertia for a person to get out of bed in the morning. A bicycle or car will keep moving unless the rider or driver applies a frictional force through the brakes to stop it. A driver of or passenger in a moving car who is not wearing a seat belt will be propelled forward when the car suddenly stops because he remains in motion. A fastened seat belt provides a restraining force on the passenger’s or driver’s motion.SECOND LAW: FORCE
Newton’s second law defines the relationship between the change in the speed of a moving object -- its acceleration -- and the force acting upon it. This force equals the object’s mass multiplied by its acceleration. It takes a smaller extra force to propel a small yacht at sea than to propel a supertanker because the latter has a greater mass than the former.
THIRD LAW: ACTION AND REACTION
Newton’s third law states that there are no isolated forces. For each force that exists, one of equal magnitude and opposite direction acts against it: action and reaction. A ball thrown onto the ground exerts a downward force. The ground in response exerts an upward force on the ball making it bounce. A person is unable to walk on the ground without the ground’s frictional force. When he takes one step forward, he exerts a backward force on the ground. The ground responds by exerting a frictional force in the opposite direction allowing the walker to move forward as he takes a further step with his other leg.
