What is the definition of velocity?
- distance travelled per unit time
- product of acceleration and change in time
- product of frequency and wavelength
- rate of change of displacement
Show answer and explanation
Answer: D. rate of change of displacement
Velocity is the rate of change of displacement.

A surveyor's device emits a pulse of light. The light is reflected from a wall 150 m away.
What is the total time taken for the pulse to travel from the device to the wall and then back to the device?
- 0.05 ns
- 0.10 ns
- 0.50 μs
- 1.0 μs
Show answer and explanation
Answer: D. 1.0 μs
t = 2d/c = (2×150)/(3.00×10⁸) = 1.0×10⁻⁶ s = 1.0 μs.

An object is moving with initial velocity u. The object then moves with uniform acceleration a for time t until it reaches final velocity v.
Which equation describes the motion of the object?
- u = v − 2at
- u = v − at
- v = u + at²
- v = u + 2at²
Show answer and explanation
Answer: B. u = v − at
Rearranging v = u + at gives u = v − at.

An object is projected from horizontal ground at a velocity of magnitude u and angle θ to the horizontal. It hits the ground at a time t after it is projected. Assume air resistance is negligible.
Which statement does not describe the motion of this object?
- The horizontal component of the object's velocity is constant and has the value ucosθ.
- The horizontal distance travelled by the object is tucosθ.
- The time taken for the object to reach maximum height is t/2.
- The vertical component of the object's velocity is constant and has the value usinθ.
Show answer and explanation
Answer: D. The vertical component of the object's velocity is constant and has the value usinθ.
The vertical component changes throughout the flight due to gravity, so it is not constant.

One object moves directly from P to R. In a shorter time, a second object moves from P to Q to R (Q not on the line PR). Which statement about the two objects is correct for the journey from P to R?
A They have the same average speed.
B They have the same average velocity.
C They have the same displacement.
D They travel the same distance.
- They have the same average speed.
- They have the same average velocity.
- They have the same displacement.
- They travel the same distance.
Show answer and explanation
Answer: C. They have the same displacement.
Displacement depends only on the start and end points (P and R), so it is the same for both objects regardless of path or time taken.

A train, initially at rest at a station, has a uniform acceleration of 0.20 m s⁻² until it reaches a speed of 20 m s⁻¹. It travels for a time at this constant speed and then has a uniform deceleration of 0.40 m s⁻² until it comes to rest at the next station. The distance between the two stations is 3000 m. What is the time taken by the train to travel between the two stations?
- 75 s
- 150 s
- 230 s
- 300 s
Show answer and explanation
Answer: C. 230 s
Accelerating: t₁ = 20/0.20 = 100 s, distance = 1000 m. Decelerating: t₃ = 20/0.40 = 50 s, distance = 500 m. Remaining distance at constant speed = 3000 − 1500 = 1500 m, t₂ = 1500/20 = 75 s. Total = 100+75+50 = 225 s ≈ 230 s.
