2.) The following graph shows how a constant force, in this case gravity (mg), acts over a distance (y): F F = mg 0. y 0. y = h, y = h, a.) Show that the shaded area under the force curve is just the potential energy stored in the object by the force AU = mgAh %3D (Hint: What is the area of a rectangle?) b.) What units does the "length" of the rectangle have? What units does the "height" of the rectangle have? What units does the area under the curve have? (You will use this result in Part I of the lab.)
