Physics 1

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

    vx = vosinθ
  4. Resultant force
  5. Gravitational force
  6. Torque


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



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


     anything above that is kinetic friction
  11. Potential energy
  12. Total mechanical energy
     = constant

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


    units: kg m/s
  18. Impulse


  19. Elastic collisions - objects dont stick
    • objects dont stick. Momentum and KE are conserved.
  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.
