Laws of Motion

The laws of motion are Newton's three fundamental principles that describe how forces affect the motion of objects. They explain why objects stay at rest or keep moving, how force produces acceleration, and why every act…

• Newton's first law: a body stays at rest or in uniform motion unless acted on by a net external force.
• Inertia is the tendency of a body to resist change in its state of rest or motion.
• Inertia depends on mass — greater mass means greater inertia.
