3. QuestionMultiple choice

What is relative velocity?

Please select an answer first.

Correct answer: C

The correct answer is The velocity of one object measured from the reference frame of another.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: Relative velocity compares motion between frames, often using v⃗A/B=v⃗A−v⃗B\vec v_{A/B}=\vec v_A-\vec v_B.
  3. Check direction and units: The correct answer is The velocity of one object measured from the reference frame of another.

Relative velocity compares motion between frames, often using v⃗A/B=v⃗A−v⃗B\vec v_{A/B}=\vec v_A-\vec v_B.

4. QuestionMultiple choice

In uniform circular motion, what continually changes?

Please select an answer first.

Correct answer: D

The correct answer is The direction of velocity.

  1. Identify the motion model: Determine whether the problem describes position, displacement, velocity, acceleration, a graph, a vector, or a specified motion scenario.
  2. Apply the kinematics relationship: Even at constant speed, changing velocity direction means the object has centripetal acceleration.
  3. Check direction and units: The correct answer is The direction of velocity.

Even at constant speed, changing velocity direction means the object has centripetal acceleration.

5. QuestionMultiple choice
