  • Answer all questions.
  • Section A: choose the one correct answer for each multiple-choice question.
  • Section B: answer in the spaces provided; show all necessary working.
  • Give numerical answers to 3 significant figures where appropriate, with units.
  • The acceleration of free fall near the Earth is 10 m/s².
  • The use of a calculator is permitted.

Original practice material written for the MOE Combined Science (Physics) syllabus. It is not an official MOE or school examination paper. Chapter 2 (speed and velocity, average speed, acceleration, distance-time and speed-time graphs, free fall).

Section A: Multiple-choice questions[10 marks]

Choose the one correct answer for each question.

  1. 1

    A runner completes 400 m in 50 s. Her average speed is

    1. A8.0 m/s
    2. B12 m/s
    3. C20 m/s
    4. D0.125 m/s
    ( )
  2. 2

    Uniform acceleration means the

    1. Aspeed is constant
    2. Bvelocity changes by equal amounts each second
    3. Cdistance is the same each second
    4. Dacceleration is zero
    ( )
  3. 3

    On a distance–time graph, a straight sloping line represents

    1. Arest
    2. Bconstant speed
    3. Cuniform acceleration
    4. Ddeceleration
    ( )
  4. 4

    A speed–time graph rises steadily from 0 to 16 m/s over 8.0 s, then stays at 16 m/s for a further 4.0 s. The total distance travelled is

    1. A64 m
    2. B80 m
    3. C128 m
    4. D256 m
    ( )
  5. 5

    A coin is dropped from rest (ignore air effects). After 2.0 s its speed is about

    1. A5.0 m/s
    2. B10 m/s
    3. C20 m/s
    4. D40 m/s
    ( )

Section B: Structured questions[20 marks]

Answer all questions in the spaces provided. Show all necessary working.

  1. 1

    A delivery van travels 18 km in 20 minutes, rests for 10 minutes, then travels a further 12 km in 30 minutes.

    1. (a)

      Calculate the total distance and total time of the journey, in km and hours.

      [2]
    2. (b)

      Calculate the average speed for the whole journey, in km/h.

      average speed =km/h[1]
    3. (c)

      Explain why the 10-minute rest is included in the calculation of average speed.

      [2]
    4. (d)

      State how the average speed would differ if the rest were excluded, and name what that quantity is sometimes called.

      [1]
  2. 2

    A escalator carries a shopper: the shopper walks 20 m in 25 s while the escalator is stationary, then stands still while it carries her 20 m in 40 s.

    1. (a)

      Calculate the shopper's walking speed and the escalator speed, in m/s.

      [2]
    2. (b)

      State which of the two speeds is a velocity measurement and why.

      [1]
    3. (c)

      The shopper then walks up the moving escalator. Estimate her speed up the slope, with a reason.

      [2]
  3. 3

    A cyclist)s journey has three stages: accelerating uniformly from rest to 10 m/s in 20 s; riding at a steady 10 m/s for 50 s; decelerating uniformly to rest in 30 s.

    1. (a)

      Calculate the acceleration in the first stage.

      acceleration =m/s²[2]
    2. (b)

      Calculate the distance covered in each of the three stages.

      [3]
    3. (c)

      Calculate the total distance and the average speed for the whole journey.

      average speed =m/s[4]
