1. The SI unit of work is the:
- (a) joule
- (b) newton
- (c) watt
- (d) pascal
2. Work done is given by:
- (a) F ÷ s
- (b) m × v
- (c) F × t
- (d) F × s
3. Kinetic energy is given by:
- (a) mv
- (b) mgh
- (c) ½mv²
- (d) Fs
4. The potential energy of a body at height h is:
- (a) ½mv²
- (b) Fs
- (c) mgh
- (d) mg
5. When is no work said to be done by a force?
6. State the law of conservation of energy.
7. Show that for a freely falling body, the total mechanical energy is conserved.

1. (a) joule — Work is measured in joules (J).
2. (d) F × s — W = F × s (force along displacement).
3. (c) ½mv² — KE = ½mv².
4. (c) mgh — PE = mgh.
5. When there is no displacement, or when the force acts perpendicular to the displacement.
6. Energy can neither be created nor destroyed; it only changes form, and the total energy remains constant.
7. At the top, the body has maximum potential energy (mgh) and zero kinetic energy. As it falls, height decreases (PE falls) while speed increases (KE rises). At each point, the loss in PE equals the gain in KE, so the sum PE + KE stays constant. Just before hitting the ground, all the energy is kinetic and equals the original potential energy — total energy is conserved.
