Study Notes
Newton's Laws of Motion
- A body remains in its state of rest or uniform motion unless acted upon by an external force.
- The time rate of change of momentum equals the force acting on a body.
Interaction of Forces
- When two bodies exert forces on each other, the forces have equal magnitude but opposite direction.
History of the Laws of Motion
- The three laws of motion were first stated by Sir Isaac Newton.
- Newton used the laws of motion to investigate and explain the motion of the Moon, the tides, and the behavior of comets.
