A ball rolling on a frictionless horizontal surface will:
A
Speed up continuously
B
Move in a circular path
C
Slow down and stop
D
Continue moving at constant velocity
Correct Answer: Option D — Continue moving at constant velocity
Explanation:
On a perfectly frictionless horizontal surface, no external horizontal force acts on the ball, so according to Newton's first law it continu...
On a perfectly frictionless horizontal surface, no external horizontal force acts on the ball, so according to Newton's first law it continues moving indefinitely at a constant velocity in a straight line.
