Question

Average speed is (less than / greater than /equal /none of these) average velocity, for a body travelling in uniform circular motion

Answer 1

Greater than...

Explanation:

Average speed is the ratio of total distance by TOTAL time taken. As average velocity depends on displacement and displacement can be zero if the object returns to initial position . ... Whereas displacement is zero as source and destination is same. Hence A body can have zero average velocity but not zero average speed. So, Average speed always greater than average velocity, for a body travelling in uniform circular motion.

Answer 2

Answer:

Explanation:

When a body travels along a circular path of constant radius with a constant ... In a uniform circular motion, velocity of a particle is not constant but its speed is ... be moving with variable speed or non-uniform speed if it covers equal distances ... actual speed of the car may be less than or greater than the average speed
