When work done on a particle is positive, then its

A

KE increases

B

KE decreases

C

KE remains constant

D

momentum increases

Text Solution

Verified by Experts

The correct Answer is:
A, D
According to work energy theorem
Work `= K_(f)-K_(i)` , when work done is positive.
This shows `K_(f)gt K_(i)`. Hence , option `(a)`.
When KE increase it mean `upsilongt u.`So` p_(f)gt p_(i)`
Hence, option `(d)`.
