Question

Please help me with this question.

Thank you!

Prelab 3: The following graph shows how a constant force, in this case gravity, acts over a distance: F = mg y=h a.) Show that the indicated area under the force curve is just the potential energy stored in the object by the force 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.)

Explanation / Answer

a) Area under the curve = Area of the highlighted rectangle = mg * (hf - ho) = mgh = U

b) In SI system, unit of the 'length' of the rectangle is meter (m). Unit of the 'height' of the rectangle is kg-ms-2 or Newton (N). Unit of the area under the curve is kg-m2s-2 or Joule (J).
