Equations of Motion

[ 1 Votes ]

The following physics revision questions are provided in support of the physics tutorial on Equations of Motion. In addition to this tutorial, we also provide revision notes, a video tutorial, revision questions on this page (which allow you to check your understanding of the topic) and calculators which provide full, step by step calculations for each of the formula in the Equations of Motion tutorials. The Equations of Motion calculators are particularly useful for ensuring your step-by-step calculations are correct as well as ensuring your final result is accurate.

Equations of Motion Revision Questions

1. An object moving linearly at 27 m/s comes to rest in 9 s after decelerating uniformly. What is the acceleration and the distance travelled by the object?

  1. Acceleration = 3 m/s2; Distance = 121.5 m
  2. Acceleration = -3 m/s2; Distance = 243 m
  3. Acceleration = 3 m/s2; Distance = 243 m
  4. Acceleration = -3 m/s2; Distance = 121.5 m

Correct Answer: D

2. An object is thrown upwards at 18 m/s. What is the height from the ground and the magnitude of the object's velocity after 2 s? For convenience, take the magnitude of the gravitational acceleration equal to 10 m/s2.

  1. Height = 16 m; |Velocity| = 2 m/s
  2. Height = 32 m; |Velocity| = 4 m/s
  3. Height = 18 m; |Velocity| = 2 m/s
  4. Height = 16 m; |Velocity| = 4 m/s

Correct Answer: A

3. An object falls from 80 m above the ground. What is the vertical distance the object has travelled during the last second of motion? For convenience, take the magnitude of the gravitational acceleration equal to 10 m/s2.

  1. 45 m
  2. 35 m
  3. 40 m
  4. 10 m

Correct Answer: B
