Science Assessment ~ Topics ~ Force and Motion ~ Misconception FMM102

Constant force produces constant speed. Under the influence of a constant force, objects move with constant velocity (Champagne et al., 1980).

Items that test for misconception FMM102 in this project (Original Project) and key idea ()
Item ID Number	Item Description	How Often the Misconception was Chosen
FM093002	A cart that is being pushed with constant force can move faster than the person pushing it if the force of the push is greater than the force of friction on the cart.	54%
FM090002	A wagon that is being pulled with a constant force can move faster than the person pulling it if the force of the pull is greater than the force of friction on the wagon.	50%
FM089002	A sled that is being pulled with a constant force can move faster than the person pulling it if the force of the pull is greater than the force of friction on the sled.	36%
FM011005	The speed of a sailboat will continue to increase the entire time the force of the wind pushing it forward is greater than the force of the water slowing it down.	36%
FM092002	A box that is being pushed with a constant force can move faster than the person pushing it if the force of the push is greater than the force of friction on the box.	30%
