Transcript

  • 1. Force & Motion 3
  • 2. Weight and Mass
    • Mass is the measure of the inertia of an object and depends on the amount of matter the objects contains
  • 3. Weight and Mass
    • Weight is the force of gravity acting on an object
  • 4. Weight and Mass
    • An objects weight is the product of the mass and acceleration due to gravity acting on it
    • W = m  g
    • F = m  a
    • g = 9.8 m/s²
  • 5. Newton’s 3 rd Law
    • Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object
  • 6. Newton’s 3 rd Law
    • Force exists in pairs
    • Action and Reaction
  • 7. Newton’s 3 rd Law
    • THINK
    • If a marble were moving 100 times faster then a shopping cart, which would be easier to stop?
  • 8. Newton’s 3 rd Law
    • The action and reaction forces do not always act on the same object
  • 9. Newton’s 3 rd Law
    • Momentum = the object’s mass  objects velocity
    • M = m  v
    • Measured in kg-m/sec
  • 10. Newton’s 3 rd Law
    • Conservation of momentum
    • If no net force acts on a system, then the total momentum of the system does not change
  • 11. Newton’s 3 rd Law
    • Conservation of momentum
    • In a closed system, the loss of momentum of one object equals the gain in momentum of another object
