Question

A particle is moving on a straight line path with constant accleration directed along the direction of instantaneous velocity. Which of the following statements are false about the motion of particle ?
A. the average velocity is less than the average speed
B. the average velocity is equal to the instaneous velocity
C. the distance covered is equal to the magnitude of displacement
D. the particle may reverse the direction of motion.

Answer 1

Correct Answer - A::B::D
Average velocity can not be compared with average speed as when body is moving with constant acclertion along a straight line , the average velocity cannot be equal to instantneous velocity. The particel moving with uniform acceleration along strainght line cannot revese the direction of its motin.
