Newton's Three Laws of Motion:
Newton's three laws of motion may be stated as follows:
1)Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
2)Force equals mass times acceleration [ f=ma ]
3)For every action there is an equal and opposite reaction.
Newton's three laws describe the relationship between the motion of objects and forces acting on the objects. Motion is produced by a force, which can be thought of as a push or a pull.
Newton's First Law says that an object in motion will stay in motion or an object at rest will stay at rest unless acted on by a force. In other words, force is necessary to change the speed or direction of a moving or still object. This is also known as the law of inertia. All objects with mass have inertia, which is resistance to change in direction.
Newton's Second Law is F=ma, or force = mass x acceleration. It says that a force acting on an object will accelerate is by an amount that's proportional to the force and inversely proportional to its mass. Force in this case is the vector sum of all forces acting on the object, and the acceleration produced in a vector quantity in the direction of the force.
Newton's Third Law says that when an object exerts a force on another object, the second object also exerts a force on the first object that is equal in magnitude an in the opposite direction. These two forces are called action and reaction forces. Motion of objects is thus produced by pairs of forces, as a force can only be applied to an object by a second object. These pairs of forces produce propulsion, for example people walking, car tires moving on roads and the thrust of rockets.
