The motion energy of an object does not depend on the mass of the object (Herrmann-Abell & DeBoer, 2009, 2010).

Items that test for misconception EGM011 in this project (ASPECt) and key idea (The amount of kinetic energy (motio…)
Item ID Number	Item Description	How Often the Misconception was Chosen
EG080002	When comparing two bike riders with different amounts of motion energy, the only way to know which one is riding faster is to also know the weight (mass) of each.	57%
EG025002	In order to know which of two objects is moving faster, you need to know the weight (mass) of each object in addition to the motion energy.	52%
RG177001	When a girl and skateboard move at the same speed, the girl has more kinetic energy because the she weighs more than the skateboard.	47%
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.	38%
EG006006	When a person is riding a bike, the person has more motion energy than the bike because the person weighs more than the bike.	30%
EG002003	For two pinecones falling at the same speed, the pinecone with more mass has more motion energy.	30%
EG007003	The motion energy of an object depends on the speed and mass of the object.	27%
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.	18%
EG009004	For two objects that are traveling at the same speed, the object with more motion energy weighs more.	16%
EG078002	When comparing two cars traveling at the same speed, the car that has more motion energy weighs more than the car that has less motion energy.	10%

Items that test for misconception EGM011 in this project (ASPECt) and other key ideas
RG174001	Kinetic energy is proportional to mass, so when a moving object has its mass increased by two the kinetic energy of that object increases by two. (Item uses bar graphs.)	44%
RG002003	Kinetic energy is proportional to mass, so when a moving object has its mass decreased by half the kinetic energy of that object decreases by half.	26%
RG001004	Doubling the speed would have the bigger impact on increasing the kinetic energy (motion energy) of a moving object because kinetic energy increases with the square of the speed	18%
RG081002	Kinetic energy is proportional to mass, so when a moving object has its mass increased by two the kinetic energy of that object increases by two.	14%
RG176001	Kinetic energy is proportional to mass, so when a moving object has its mass increased by two the kinetic energy of that object increases by two.	13%
