Science Assessment ~ Topics ~ Force and Motion ~ Misconception FMM125

When a force acts on a moving object to slow the object down, the object will slow down for a while and then move at a lower constant speed (AAAS Project 2061, n.d.).

Items that test for misconception FMM125 in this project (Original Project) and key idea ()
Item ID Number	Item Description	How Often the Misconception was Chosen
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.	39%
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.	23%
FM069005	Use of tables of speed versus time, and information about forces acting on an object, to determine the object's speed at various times.	21%
FM103001	Use of tables of speed versus time, and information about forces acting on an object, to determine the object's speed at various times.	19%
FM101001	If an object is moving forward, and a force pushing it backward is greater than a force pushing forward, the object will slow down, stop, and then begin to move faster and faster in the opposite direction.	18%
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.	15%
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.	10%
FM096001	A hockey puck that is sliding across the ice will move slower and slower the entire time it slides across the ice.	8%
