An object moves in a circular path at a constant
speed. Compare the direction of the object's velocity
and acceleration vectors.
Both vectors point in the same direction.
The vectors point in opposite directions.
The vectors are perpendicular.
The question is meaningless, since the
acceleration is zero.
When an object experiences uniform circular
motion, the direction of the net force is:
in the same direction as the motion of the object.
in the opposite direction of the motion of the
object.
is directed toward the center of the circular path.
is directed away from the center of the circular
path.
Is it possible for an object moving with a constant
speed to accelerate? Explain.
No, if the speed is constant then the
acceleration is equal to zero.
No, an object can accelerate only if there is a
net force acting on it.
Yes, although the speed is constant, the
direction of the velocity can be changing.
Yes, if an object is moving it is experiencing
acceleration
