First Law (Inertia) An object at rest stays at rest. An object in motion continues in motion unless acted on by a net force. Example: A soccer ball won’t move until you kick it.
Second Law (F = ma) Force = Mass × Acceleration Explains how much force is needed to move objects. Example: Pushing an empty cart vs. a full cart.
Third Law (Action–Reaction) For every action, there is an equal and opposite reaction. Example: A rocket pushes gases down, gases push rocket up.
Summary 1st Law: Inertia 2nd Law: Force and acceleration 3rd Law: Action–reaction Newton’s Laws explain everyday motion!
