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 (Original Project) and key idea (If a force acts on an object in the…)
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%
