Science Assessment ~ Topics ~ Energy: Forms, Transformation, Transfer, and Conservation ~ Misconception EGM054

When comparing two objects, the object that has more motion energy, weighs more (has more mass) regardless of the speed of the two objects (AAAS Project 2061, n.d.).

Items that test for misconception EGM054 in this project (ASPECt) and key idea ()
Item ID Number	Item Description	How Often the Misconception was Chosen
EG024002	In order to know which of two objects weighs more, you need to know the speed of each object in addition to the motion energy.	28%
EG079002	When comparing two runners with different amounts of motion energy, the only way to know which one weighs more is to also know how fast each is running.	21%
EG076002	A basket ball has more motion energy than a boy when the ball is moving through the air and the boy is standing still.	13%
EG012003	A ball has more motion energy than a person when the ball is moving and the person is not moving.	13%
