What to Focus On

  • Work is done only when force causes motion.
  • Energy is the capacity to do work.
  • Work done = Force × Distance moved in the direction of force.

  • The S.I. unit of energy is joule.
  • 1 cal = 4·2 J (nearly).
  • 1 kcal = 1000 cal.

  • Mechanical energy has two forms: potential and kinetic.
  • Heat energy comes from burning fuels.
  • Light energy makes objects visible.

Common Mistakes to Avoid

Energy and work are the same thing.

If a force is applied, work is always done.

Joule is the unit of force or distance.
