Multiple Choice
Which statement is correct when an object experiences uniform circular motion;
direction of speed is uniform
velocity is constant
magnitude of velocity is not uniform
its speed is constant
2.
Multiple Choice
Is it possible for an object moving with a constant speed to accelerate?
No, if the speed is constant then the acceleration is equal to zero
Yes, although the speed is constant, the direction of the velocity can be changing
No, an object can accelerate only if there is a net force acting on it
Yes, if an object is moving it can experience acceleration
