URGENT HELP PLS 1. Given a force-displacement curve as shown in the figure, what does the area of the region enclosed by the curve represent?

A. The force acting on the object

B. The displacement of the object

C. The magnitude of the coefficient of static friction

D. The work done on the object by the force

Explanation:

work done is equals to force into displacement in the direction of force

Ans: D

chemical properties of thing

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
