Force, Work, Power and Energy

  • Second law of motion

    • The second law of motion says, when a force F is subjected to a body of mass m, an acceleration a is gained by the body in the direction of the force and the magnitude of acceleration is directly proportional to the F and inversely proportional to the m.

    • Rate of change of momentum ∝ Applied unbalanced force

    • Direction of change in momentum is the same as the direction of unbalanced force

F = ma

Unit of force is Newton

1 N = 1 kg × 1 m / s2

  • Linear or translation motion
  • Rotationa…
