- 17. Multiple ChoiceIs 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 accelerationABCD - 18. Multiple ChoiceAn 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 zeroABCD - 19. Multiple Choice

- 25. Multiple Choice
Two riders sit at positions X and Y. Do they have different periods of rotation and why / why not?
No, because they have the same tangential velocity.
No, because they take the same amount of time to complete 1 loop.
Yes, because they have different tangential velocities.
Yes, because they have different masses probably.
