Newtons three laws are how you describe movement, and that is life. His first law is "Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." An example of this law is, if you where riding a skateboard and you fly forward off the board when hitting a curb or rock or other object that abruptly halts the motion of the skateboard.
The second law says, "The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector." This is the most important law out of the three. The law states that the acceleration of an object is dependent upon two variables, the net force acting upon the object and the mass of the object. As the mass of an object is increased, the acceleration of the object is decreased.
The last law is, "For every action there is an equal and opposite reaction." Basicly it means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs, equal and opposite action reaction force pairs. Think of it as if we step off a boat onto the bank of a lake; as we move in the direction of the shore, the boat tends to move in the opposite direction
