For a ball traveling over a frictionless hill, the steepness of the path is the most important factor affecting the ball’s speed and motion energy (Duit, 1981).

Items that test for misconception NGM043 in this project (Original Project) and key idea (Regardless of what happens within a…)
Item ID Number	Item Description	How Often the Misconception was Chosen
NG094002	Assuming no energy transfer between a ball and the track it is moving in, the amount of energy the ball has after it goes over a hill will be the same as before it went over the hill because the total amount of energy in the system did not change.	44%
NG095002	The total amount of energy a ball has does not change after it goes down and up a dip because the total energy of the system (ball and track) does not change (assuming no energy transfer between the ball and the track and the ball and the air around it).	37%
NG092002	Assuming no energy transfer between a ball and the track it is moving in, the amount of energy the ball has after it goes over a hill will be the same as before it went over the hill.	18%
NG096002	The total amount of energy a ball has does not change after it goes down and up a dip because the total energy of the system (ball and track) does not change (assuming no energy transfer between the ball and the track and the ball and the air around it).	15%
