- 1. The force of attraction between any two masses is:
- (a) tension
- (b) magnetism
- (c) gravitation
- (d) friction
- 2. In F = Gm₁m₂/r², the force is inversely proportional to:
- (a) r²
- (b) m₁
- (c) G
- (d) r
- 3. The weight of a body is given by:
- (a) g/m
- (b) ma only
- (c) m/g
- (d) mg
- 4. The value of g near the Earth's surface is about:
- (a) 9.8 m/s²
- (b) 1.8 m/s²
- (c) 10.8 m/s²
- (d) 8.9 m/s²
- 5. What is the difference between mass and weight?
- 6. State Archimedes' principle.
- 7. State the universal law of gravitation and define the gravitational constant G.

- 1. (c) gravitation — It is the gravitational force.
- 2. (a) r² — It varies inversely with the square of the distance.
- 3. (d) mg — W = mg.
- 4. (a) 9.8 m/s² — g ≈ 9.8 m/s².
- 5. Mass is the amount of matter (constant); weight is the gravitational force on it (W = mg), which varies with g.
- 6. A body immersed in a fluid experiences an upward thrust equal to the weight of the fluid it displaces.
- 7. Every object attracts every other object with a force F = Gm₁m₂/r², directly proportional to the product of their masses and inversely proportional to the square of the distance between them. G is the universal gravitational constant — the force between two unit masses placed one unit distance apart — with value about 6.67 × 10⁻¹¹ N·m²/kg².
