Question

A body moves from rest with a constant acceleration. Which one of the following graphs represents the variation of its kinetic energy $K$ with the distance travelled $x$?

• A. Diagram
• B. Diagram
• C. Diagram
• D. Diagram

Answer 1

The correct option is B Diagram

When body moves under action of constant force then kinetic energy acquired by the body will be equal to the work done by the all the forces act on the body.
$K.E.=F\times S$

$\therefore K.E.\propto S$ ( If $F$ = constant )
So the graph will be straight line.

Final answer: (c)
