Worked practice questions

For a round trip from home to school and back, displacement equals:

  1. Zero
  2. Twice the distance one way
  3. Same as distance
  4. Cannot be calculated
Show answer and solution

Correct answer: A. Zero

Displacement is the straight-line vector from start to end. A round trip ends where it started, so displacement is zero, even though distance is nonzero.

Acceleration is defined as:

  1. Change in distance per time
  2. Change in velocity per time
  3. Velocity divided by mass
  4. Speed divided by distance
Show answer and solution

Correct answer: B. Change in velocity per time

a = Δv / Δt. SI unit: m/s². Velocity changes can be in magnitude, direction, or both.
