The 20 questions

  1. Acceleration is calculated as change in velocity divided by:

    • Total mass
    • Initial speed
    • Time taken
    • Distance travelled

  2. What is the standard unit of acceleration?

    • m2/s
    • m/s2
    • N/kg
    • m/s

  3. An object that slows down is said to be:

    • Decelerating
    • Stationary
    • Accelerating uniformly
    • At terminal velocity

  4. Near the Earth's surface, a freely falling object has an acceleration of about:

    • 9.8 m/s
    • 0.98 m/s2
    • 9.8 m/s2
    • 98 m/s2

  5. What is zero when a falling object reaches terminal velocity?

    • Speed
    • Air resistance
    • Weight
    • Resultant force

  6. What does the gradient of a velocity-time graph represent?

    • Speed
    • Distance
    • Acceleration
    • Force

  7. A car speeds up from 0 to 12 m/s in 4 s. Its acceleration is:

    • 3 m/s2
    • 8 m/s2
    • 48 m/s2
    • 0.33 m/s2

  8. A cyclist slows from 8 m/s to 2 m/s in 3 s. The magnitude of her deceleration is:

    • 0.4 m/s2
    • 3 m/s2
    • 6 m/s2
    • 2 m/s2

  9. An object accelerates from rest at 2 m/s2 for 5 s. Its final velocity is:

    • 10 m/s
    • 2.5 m/s
    • 0.4 m/s
    • 25 m/s

  10. A typical car accelerating gently from rest has an acceleration of roughly:

    • 0.002 m/s2
    • 200 m/s2
    • 20000 m/s2
    • 2 m/s2

  11. An object starts from rest and accelerates uniformly at 2 m/s2 over 25 m. Its final speed is:

    • 25 m/s
    • 5 m/s
    • 10 m/s
    • 50 m/s

  12. A vehicle moving at 20 m/s decelerates uniformly at 4 m/s2 until it stops. Its stopping distance is:

    • 80 m
    • 5 m
    • 200 m
    • 50 m

  13. A ball is dropped from rest. Its speed reaches 49 m/s after about:

    • 5 s
    • 9.8 s
    • 49 s
    • 0.2 s

    • 48 m
    • 84 m
    • 120 m
    • 36 m

  16. (HT only) The area under a velocity-time graph for a constant 5 m/s over 8 s is:

    • 8 m
    • 5 m
    • 13 m
    • 40 m

  17. What does a horizontal line on a velocity-time graph indicate?

    • Zero acceleration
    • Deceleration
    • Zero speed
    • Constant acceleration

  18. A ball falls from rest, ignoring air resistance. Its velocity after 2 s is about:

    • 4.9 m/s
    • 39.2 m/s

    • Car B
    • Both equal
    • Cannot tell
    • Car A
