Newton's First Law Of Motion
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
Newton's second law is one of the most important laws you'll learn. The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
The 3rd Law Of Motion
The Third Law is concerned with how objects push on each other and exchange momentum when they interact. The third law states that for every force there is an equal and opposite force.
