1Which of the following is a vector quantity?

A.Displacement

B.Distance

C.Speed

D.Time

Explanation: Vector quantities have both magnitude and direction. Displacement is the straight-line distance and direction from start to finish, so it is a vector. Distance, speed and time are scalars.

2A pupil walks 30 m east, then 40 m north. What is the magnitude of the resultant displacement?

A.50 m

B.70 m

C.10 m

D.35 m

Explanation: Using Pythagoras on perpendicular components: sqrt(30^2 + 40^2) = sqrt(900 + 1600) = sqrt(2500) = 50 m. This is a classic 3-4-5 triangle scaled by 10.

3A cyclist travels 1200 m in 5 minutes. What is the average speed in m/s?

A.4 m/s

B.240 m/s

C.0.25 m/s

D.6 m/s

Explanation: Convert time to seconds: 5 min = 300 s. Average speed = distance / time = 1200 / 300 = 4 m/s.

4A car accelerates from 8 m/s to 20 m/s in 4 s. What is its acceleration?

A.3 m/s^2

B.5 m/s^2

C.7 m/s^2

D.12 m/s^2

Explanation: a = (v - u) / t = (20 - 8) / 4 = 12 / 4 = 3 m/s^2.

5On a speed-time graph, what does the area under the line represent?

A.Distance travelled

B.Acceleration

C.Average speed

D.Final velocity

Explanation: Speed multiplied by time gives distance. Geometrically, the area under a speed-time graph equals distance travelled regardless of shape (rectangles, triangles or combinations).

6A trolley accelerates uniformly from rest, reaching 10 m/s in 5 s, then travels at 10 m/s for 10 s. What total distance has it covered after 15 s?

A.125 m

B.150 m

C.100 m

D.75 m

Explanation: Acceleration phase: triangle area = 0.5 x 5 x 10 = 25 m. Constant-speed phase: rectangle area = 10 x 10 = 100 m. Total = 25 + 100 = 125 m.

7Which statement best expresses Newton's first law of motion?

A.An object stays at rest or moves at constant velocity unless acted on by an unbalanced force

B.Force equals mass times acceleration

C.For every action there is an equal and opposite reaction

D.Heavier objects always accelerate faster than lighter ones

Explanation: Newton's first law (the law of inertia) states that an object's motion will not change unless an unbalanced (resultant) force acts on it. Balanced forces produce no change in velocity.

8A 6 kg object experiences an unbalanced force of 24 N. What is its acceleration?

A.4 m/s^2

B.0.25 m/s^2

C.144 m/s^2

D.30 m/s^2

Explanation: Using F = ma, rearrange to a = F / m = 24 / 6 = 4 m/s^2.

9An astronaut has a mass of 70 kg. What is her weight on Earth where g = 9.8 N/kg?

A.686 N

B.70 N

C.7.14 N

D.9.8 N

Explanation: Weight W = mg = 70 x 9.8 = 686 N. Weight is a force measured in newtons and depends on the local gravitational field strength.

10A car of mass 1200 kg has a driving force of 4800 N and a friction force of 1200 N. What is its acceleration?

A.3 m/s^2

B.5 m/s^2

C.4 m/s^2

D.0.33 m/s^2

Explanation: Resultant force = 4800 - 1200 = 3600 N. Then a = F / m = 3600 / 1200 = 3 m/s^2. The friction force opposes motion and must be subtracted.

National 5 Physics Study Tips from Top Performers

1Work through past papers from sqa.org.uk under timed conditions — the multiple-choice section is short and rewards fluency with the relationships sheet

2Memorise the relationships sheet symbols and units; many marks are awarded for correctly substituting numbers with units

3Practise rearranging formulas such as v=fλ, V=IR and Eh=cmΔT before exam day so you can pivot quickly between unknowns

4Revise the assignment skills (uncertainty, control of variables, conclusion) alongside content — the 20 assignment marks affect your overall grade
