Key Topics to Revise

1

1. Work and its conditions

  • Work is done only when force is applied and the body moves through some distance in the direction of the force.
  • No work is done if a force is applied but the body does not move.
  • No work is done if no force is applied and the body is at rest or moving with constant velocity.

2. Units and relation of work with energy

  • The SI unit of work is newton-metre or joule.
  • Energy has the same unit as work, joule.
  • Energy is the ability to do work.

3. Mechanical energy: potential energy and kinetic energy

  • Mechanical energy is the energy a body has because of its position or motion.
  • Potential energy is energy possessed by a body raised above the ground.
  • Potential energy depends on the weight of the body and its height above the ground.

4. Forms of energy and their examples

  • Energy is found in many forms: mechanical, thermal, light, electrical, magnetic, sound, and nuclear.
  • Thermal energy gives the sensation of hotness flowing into the body and coldness flowing out.
  • Light energy enables us to see things.
