Question

When force and displacement act along same direction, then

• A. K.E. of body must remain constant
• B. K.E. of body must decrease
• C. K.E. of body must increase
• D. P.E. of body decreases

Answer 1

The correct option is C K.E. of body must increase

According to Work Energy Theorem:
Work done = $\Delta K.E.$

So, if work done is positive, then kinetic energy must increase.
