Study Notes
Newton's Laws of Motion
- Sir Isaac Newton formulated the three laws of motion.
First Law (Law of Inertia)
- Inertia refers to an object's tendency to resist changes in its motion, remaining at rest or continuing to move with a constant velocity unless acted upon by an external force.
Second Law (Force and Acceleration)
- The second law describes the relationship between an object's mass, acceleration, and the applied force.
- Force (F) is equal to the mass (m) of an object multiplied by its acceleration (a), i.e., F = ma.
Third Law (Action and Reaction)
- The action-reaction pair associated with Newton's third law of motion states that for every action, there is an equal and opposite reaction.
- When object A exerts a force on object B, object B simultaneously exerts an equal and opposite force on object A.
