AAAS Science Assessment ~ Topics ~ Force and Motion ~ Misconception FMM128

When a force acts on a moving object in the direction opposite the object’s direction of motion, the object will move at a constant speed the entire time (AAAS Project 2061, n.d.).

Items that test for misconception FMM128 in this project () and key idea ()
Item ID Number	Item Description	How Often the Misconception was Chosen
FM055004	The speed of a sailboat will continue to decrease the entire time the force of the water slowing it down is greater than the force of the wind pushing it forward.	26%
FM098002	A moving snowmobile will slow down the entire time that the force of the wind moving toward the snowmobile is greater than the force moving the snowmobile forward.	14%
FM095001	A moving object will slow down the entire time that a force that opposes its motion is greater than the force pushing or pulling it forward.	14%
FM097002	A snowmobile sliding across a lake with its engine turned off will move slower and slower the entire tme it is sliding across the lake.	13%
FM096001	A hockey puck that is sliding across the ice will move slower and slower the entire time it slides across the ice.	13%
