  1. Name newton's laws of motion
    • ƒÞ Law of Inertia
    • ƒÞ Law of Acceleration
    • ƒÞ Law of Action-Reaction
  2. What is the law of inertia
    A body remains at rest or in constant linear velocity except when compelled by an external force to chang it stae
  3. What is the law of acceleration?
    The linear acceleration of a body is directly proportional to the force causing it, take place in the smae direction in whihc the force acts, and is inversly proportional to the mass of the body
  4. What is the the law of action reaction
    For every force there is an equal and opposite directed force.
  5. what is (p) a symbol for
    Radius of gyration
  6. What is the Radius of gyration
    distance between the axis of rotation and the center of mass
  7. What is (I)
    mass moment of inertia
  8. what is the formula for Mass moment of inertia (I)
    (I) = mass X p2
  9. What is the formula for Force
    Force = mass X acceleration
  10. What is the formula for torque
    Torque (moment) = I X angular acceleration
  11. Momentum
    Momentum = mass X velocity
  12. Impulse
    Impulse = force (T) X time
  13. Work
    Work = F (T) X displacement
  14. Power
    Power = work / time
  15. Linear power
    = F X d/t (or velocity)
  16. Angular power
    Angular power = T X angular velocity (ù)
