Grade 7 Science – Acceleration Quiz
Instructions: Answer the following questions. For multiple choice, circle the
correct answer.
Section A: Multiple Choice (1 mark each)
1. What is acceleration?
a) The speed of an object
b) The change in position
c) The rate of change of velocity
d) The time taken to travel
2. An object is accelerating if:
a) It moves in a straight line at a constant speed
b) Its direction or speed changes
c) It stays at rest
d) It moves in a circle at a constant speed
3. If a car speeds up from 10 m/s to 30 m/s in 4 seconds, what is its
acceleration? a) 5 m/s²
b) 10 m/s²
c) 20 m/s²
d) 40 m/s²
4. Which of the following is an example of deceleration?
a) A rocket lifting off
b) A car coming to a stop
c) A plane taking off
d) A train moving at a constant speed
Section B: True or False (1 mark each)
5. Acceleration can be negative.
6. If an object is not moving, it still has acceleration.
7. A change in direction is a form of acceleration.
8. Acceleration is measured in meters per second squared (m/s²).
Section C: Short Answer (2 marks each)
9. Define acceleration in your own words.
10.A bicycle goes from rest to 6 m/s in 3 seconds. Calculate its acceleration.
11.Explain why a car turning around a corner at a constant speed is still
considered to be accelerating.
