1. Any particle which moves in uniform circular motion (i.e. constant speed) must have ZERO net force acting on it
II. If a non-zero net force acts on a particle, the particle's velocity will change.
III. If frictional forces are present, Newton's second law (Ēnce = mā) is no longer exactly true
O All of the above are true
O All are false
O Only II is true
O Only III is true​
