Question

Determining the area underneath which of the following curves is a viable method for determining the work done on an object?

A. Kinetic Energy vs. Elapsed Time

B. Force vs. Elapsed Time

C. Force vs. Change in Displacement

D. Potential Energy vs. Kinetic Energy

Answer 1

Ans is C

as work done = force* Displacement in the direction of force

If force is constant the its a rectangle

If force is variable it is a triangle or area under the curve
