Misconception EGM015:

Motion energy depends on the effort required to move the object not the speed of the object. For example, an object rolling down a hill at 5 miles per hour will have a different amount of motion energy than an object rolling up a hill at 5 miles per hour or a person has a different amount of motion energy when walking through water than they do when walking through air at the same speed. For some students energy is associated with the difficulty with which an object is moved or how hard a person has to pull or push (Brook & Driver, 1984).
