Potential energies, on the other hand, are way of easily calculating howa
conservative force will change a KE if an object changes position. Thatis
difficult, if not impossible, for a student to associate with a concrete
image.

B) Student pilots have an _easier_ time estimating their height (PE)
than their airspeed (KE).
