What to Focus On

  • Dot product: A · B = AB cos θ
  • Work: W = Fd cos θ
  • Work is scalar and may be positive, negative, or zero

  • Work-energy theorem: change in kinetic energy equals work done by net force
  • For constant force: Kf − Ki = W
  • The theorem follows from Newton’s Second Law

  • K = 1/2 mv2
  • Kinetic energy depends on mass and speed
  • Kinetic energy is scalar

Common Mistakes to Avoid

Work is done whenever a force is applied, even if there is no displacement.

Work done by action-reaction forces must always be equal and opposite.

Positive work means the force must be large, and negative work means the force is bad or incorrect.

Memory Tips

Work and energy have the same dimensions and unit

Power and its unit

No work is done in three special cases

Positive and negative work
