if work done by a conservative force is positive the select the correct option(s).
(a) potential energy will decrease.
(b) potential energy may increase or decrease.
(c )kinetic energy will increase.
(d) kinetic energy may increase or decrease.

Text Solution

Verified by Experts

The correct Answer is:
A, D
`DeltaU =-W`
so, if work done by conservative force is positive then `DeltaU` is negative or potential energy will decrease. But there is no straight forward rule regarding the kinetic energy.
