If a particle moving in a vertical straight line is

A

moving up and speeding up then its acceleration must be upward.

B

moving up and slowing down then its acceleration must be downward.

C

moving down and speeding up then its acceleration must be downward.

D

moving down and slowing down then its acceleration must be upward.

Text Solution

Verified by Experts

The correct Answer is:
a,b,c,d
When velocity and acceleration are in the same direction then magnitude of velocity increses. When Velocity and acceleration are along the opposite direction then magnitude of velocity decreases.
