Displacement
1. When an object is moving at constant speed, which of the following is always true?
- A. Distance is greater than displacement
- B. Distance is less than displacement
- C. Distance is equal to displacement
- D. There is not enough information available
View answer and explanation
Answer: D. There is not enough information available
At constant speed, distance equals the total path length while displacement is the straight-line change of position, so their relation depends on the shape of the path. If the path is straight, they are equal; if it curves or reverses, distance exceeds displacement. Since the path is not specified, there is not enough information to compare them.
Momentum
2. Two objects of equal mass move in opposite directions with equal speeds. What is the total momentum of the system?
- A. Zero
- B. Half the momentum of one object
- C. Twice the momentum of one object
- D. Cannot be determined
View answer and explanation
Answer: A. Zero
The two momenta are equal in magnitude but opposite in direction (m v and -m v), so their vector sum is zero. Total momentum is a vector sum, not a sum of magnitudes.
Acceleration
3. A body is in equilibrium when it has ______?
- A. Uniform speed
- B. Uniform acceleration
- C. Both a and b
- D. Zero acceleration
View answer and explanation
Answer: D. Zero acceleration
A body is in equilibrium when the net force acting on it is zero, and it is not changing its motion. This means that the body is either at rest or moving with a constant velocity (uniform speed), but not accelerating.
About this unit

Common questions about Force and Motion practice
How many Force and Motion MCQs are available on DIFF. MDCAT?
The current Force and Motion question bank contains 1,127 practice MCQs across 8 topics. This is the bank size, not the length of one test. Choose your topics and a question count from 1 to 180, limited by the questions available in those topics.
Which topics does the Force and Motion quiz cover?
The selectable topics are Displacement, Velocity, Motion Graphs, Acceleration, Projectile Motion, Newton's Laws, Momentum, Collisions. Use Select all for a broad chapter drill, Clear to start a focused selection, or choose individual topics. Questions are drawn from your chosen topics, so you can target a weak concept before returning to a wider test.
How do I build a custom Force and Motion test?
Open the chapter builder, select one or more topics, enter your question count, and choose Tutor Mode or Timed Exam. The available-question total updates with your selection. Start Test generates a shuffled drill; you do not have to follow a fixed Quiz 1 or Quiz 2 sequence.
What is the difference between Tutor Mode and Timed Exam?
Tutor Mode gives feedback and an explanation after you choose an option, and you can change or clear that choice. Timed Exam runs a countdown and keeps explanations hidden until submission. Both modes let you move between questions, use the paper map, and submit for a complete review.
How do I review and download my Force and Motion quiz?
Select Submit Quiz, then Submit & View Explanations. The review includes every question in your test, all options, your selection, the marked correct answer when a key is available, and the explanation. Download PDF saves a paginated review; Download Review saves an HTML copy you can open in a browser. The review also includes DIFF. MDCAT community links.
How should I use Force and Motion MCQs to improve?
Start with a short tutor drill on one of these topics: Displacement, Velocity, Motion Graphs. Read the explanation for incorrect and uncertain answers, revise the relevant textbook section, and retry before taking a timed drill. Compare your reasoning with the answer key rather than memorising the option letter.
