Students are introduced to Newton’s three laws of motion – Newton’s first law of motion (inertia), Newton’s second law of motion (F=ma) and Newton’s third law of motion (for every action, there is an equal and opposite reaction).
Concept: Newton’s third law
The last of Sir Isaac Newton’s three laws of motion, Newton’s third law says “For every action there is an equal and opposite reaction.”
The two equal and opposite forces that the two objects exert on each other are called the action-reaction pair.
