  1. The Nature of a Force A push or pull on an object (starting text page 312)

  2. Isaac Newton Discovered 3 Laws Of Motion in the 1600’s Newton’s Laws of Motion

  3. Newton’sFirst Law of Motion • An object at rest will stay at rest unless an unbalanced object acts upon it • An object moving at a constant velocity (speed) will continue to move at that speed unless an unbalanced forces stops it • This law is also called the Law of Inertia. • Inertia- the desire for an object to resist change in motion. Or the desire for an object to stay in place

  4. Newton’sSecond Law of Motion The net force of an object is equal to the product of its acceleration and mass. F= m x a You can change acceleration by changing the mass a= F m

  5. Newton’s Third Law of Motion • Every action has an equal but opposite reaction • If one object exerts a force on another object, then the second object will exert a force in the opposite direction
