TuitionGoWhere Practice Paper — Answer Key (Version 5)

Subject: Physics H1 | Level: A-Level | Topic: Mechanics | Total Marks: 60

Section A: Kinematics & Dynamics

Q1. [1 mark]
Velocity = gradient of displacement–time graph. From $t=4$ to $t=7$ , displacement constant at $20\ \text{m}$ → gradient = 0.
Answer: $0\ \text{m s}^{-1}$ (or stationary).
Teaching note: Horizontal line on s–t graph means no change in position → zero velocity.

Q2. [2 marks]
Answer: Displacement is the distance moved in a specified direction from a fixed reference point (or: shortest vector from initial to final position).
Marks: [B1] distance/magnitude, [B1] direction / vector nature.
Common trap: Stating “distance” only (no direction) loses 1 mark.

Q3. [2 marks]
Use $s = ut + \frac{1}{2}gt^2$ , $u=0$ :
$s = 0 + \frac{1}{2}(9.8)(3.0)^2 = 4.9 \times 9 = 44.1\ \text{m}$ .
