A car travels along a road at x, where x is 15 m / s due north.
Which term describes x?
- acceleration
- scalar
- speed
- vector
Show answer and explanation
Answer: D. vector
15 m/s due north has both size and direction, so it is a velocity, which is a vector quantity.
Oct/Nov 2025 · Paper 1 · General physics
Quantities can be described as scalar or vector.
Which row shows scalar quantities and vector quantities?
- scalar: displacement, force, temperature — vector: distance, weight, mass
- scalar: displacement, mass, force — vector: distance, weight, temperature
- scalar: distance, force, weight — vector: displacement, mass, temperature
- scalar: distance, mass, temperature — vector: displacement, force, weight
Show answer and explanation
Answer: D. scalar: distance, mass, temperature — vector: displacement, force, weight
Distance, mass and temperature have magnitude only (scalars); displacement, force and weight also have direction (vectors).

A student determines the density of a solid metal cube.
Which pieces of equipment does the student use?
- a balance and a force meter
- a balance and a ruler
- a micrometer and a measuring cylinder
- a ruler and a measuring cylinder
Show answer and explanation
Answer: B. a balance and a ruler
Density needs mass and volume: the balance gives the mass and the ruler gives the side length, from which the volume of a cube is calculated.

Three forces of 3 N, 11 N and 2 N act on a block. Together they give a resultant force of 6 N to the right.
One additional force is now applied to the block so that the resultant force on it becomes 3 N to the left.
Which additional force produces this resultant force of 3 N to the left?
- 3 N to the left
- 9 N to the left
- 6 N to the right
- 13 N to the right
Show answer and explanation
Answer: B. 9 N to the left
The resultant must change from 6 N right to 3 N left, a change of 9 N in the leftward direction, so the extra force is 9 N to the left.
Oct/Nov 2021 · Paper 1 · General physics
Which quantity is a vector?
- speed
- force
- mass
- distance
Show answer and explanation
Answer: B. force
Weight/force has both magnitude and direction, so it is a vector; speed, mass and distance are scalars.

An underwater diver moves from the ocean (denser water) to a fresh water lake (less dense water). In which position does the diver experience the smallest pressure due to the water: point A (shallow, ocean), point B (deep, ocean), point C (shallow, lake), or point D (deep, lake)?
- A (shallow, ocean)
- B (deep, ocean)
- C (shallow, lake)
- D (deep, lake)
Show answer and explanation
Answer: C. C (shallow, lake)
Pressure due to a liquid = ρgh, so pressure is smallest where both depth and density are smallest — the shallow point in the less dense lake water, point C.
