  1. Velocity
    Image Upload 2
  2. Acceleration
    Image Upload 4
  3. X and Y components of initial velocity
    vy = vocosθ

    vx = vosinθ
  4. Resultant force
    Image Upload 6
  5. Gravitational force
    Image Upload 8
  6. Torque
    Image Upload 10

    • r = distance between fulcrum and force
    • θ = angle between force and lever arm
  7. Centripetal force
    Image Upload 12
  8. Centripetal acceleration
    Image Upload 14
  9. Kinetic friction
    Image Upload 16


    • μk = coefficient of kinetic friction
    • Fn = normal force
  10. static friction
    Image Upload 18

    Image Upload 20 anything above that is kinetic friction
  11. Potential energy
    Image Upload 22
  12. Total mechanical energy
    Image Upload 24 = constant

    • When there's no friction/air resistance
    • Image Upload 26
  13. Work done by non conservative forces
    Image Upload 28
  14. Work
    W = Fdcosθ
  15. Power
    • Image Upload 30 
    • J/s = watts
  16. Work Energy theorem
    Image Upload 32
  17. Momentum
    Image Upload 34

    units: kg m/s
  18. Impulse
    Image Upload 36

  19. Elastic collisions - objects dont stick
    • objects dont stick. Momentum and KE are conserved.
    • Image Upload 40
    • Image Upload 42
  20. Inelastic collisions
    • Kinetic energy is lost in the form of heat, light or sound therefore final KE is less that initial.
    • Momentum is conserved
  21. Completely Inelastic collisions
    • Objects stick together
    • Kinetic energy is not conserved. 
    • Momentum is conserved, objects have the same velocity after combining.
