alleryIn uniform motion, how does instantaneous velocity vary with time?
AIt drops rapidly
BIt drifts rapidly
CIt does not vary
DIt doubles rapidly
Answer & Solution
Correct answer: C. It does not vary
1. Uniform motion is defined by an unchanging velocity.
2. Every instant therefore reads the same.
3. For uniform motion, velocity is the same as the average velocity at all instants.
4. So the answer is it does not vary.
