Circular Motion Quizzes & Trivia

Questions and Answers
  • 1. 
    Is it possible for an object moving with a constant speed to accelerate? Explain.
    • A. 

      No, if the speed is constant then the acceleration is equal to zero.

    • B. 

      No, an object can accelerate only if there is a net force acting on it.

    • C. 

      Yes, although the speed is constant, the direction of the velocity can be changing.

    • D. 

      Yes, if an object is moving it can experience acceleration.

  • 2. 
    Consider a particle moving with constant speed such that its acceleration of constant magnitude is always perpendicular to its velocity.
    • A. 

      It is moving in a straight line.

    • B. 

      It is moving in a circle.

    • C. 

      It is moving in a parabola.

    • D. 

      None of the above is definitely true all of the time.

  • 3. 
    An object moves in a circular path at a constant speed. Compare the direction of the object's velocity and acceleration vectors.
    • A. 

      Both vectors point in the same direction.

    • B. 

      The vectors point in opposite directions.

    • C. 

      The vectors are perpendicular.

    • D. 

      The question is meaningless, since the acceleration is zero.

  • 4. 
    When an object experiences uniform circular motion, the direction of the acceleration is
    • A. 

      In the same direction as the velocity vector.

    • B. 

      In the opposite direction of the velocity vector.

    • C. 

      Is directed toward the center of the circular path.

    • D. 

      Is directed away from the center of the circular path.
