1. Topic: Force and Motion
a. Question:
i. A penguin is pushed off a cliff by another penguin. Describe the forces on
the penguin after it leaves the cliff but before it hits the water?
1. Only the force of the earth’s gravity on the penguin
2. Only the force the penguin got from being pushed off the cliff
3. Both the force of the earth’s gravity on the penguin and the force
the penguin got from being pushed off the cliff
4. Neither the force of the earth’s gravity on the penguin nor the force
the penguin got from being pushed off the cliff
ii.
Correct Answer
1
b. Misconceptions
i. Answer Choices: 2, 3
ii.
FMM114: An impelling force (impulse or impetus) can become part of an
object. For example, the force involved in throwing or hitting an object
becomes part of the thrown or hit object (McCloskey, 1983; Fischbein et
al., 1989).
2.Item ID : Item FM054002
a. Question
i. What are the forces acting on the balloonist in the picture? (consider the
man and the chair to be one object)
1. Only the pull of the rope on the tire
2. Only the pull of earth’s gravity on the tire
3. Both the pull of the rope on the tire and the pull of earth’s gravity
on the tire
4. Neither the pull of the rope on the tire nor the pull of earth’s
gravity on the tire
ii.
Correct Answer
3
b. Misconceptions
i. Answer Choices: 2, 4
ii.

(AAAS Project 2061, n.d.).

3.Item FM075004:
a. Question
i. In the drawing below, the arrows labeled Force 1 and Force 2 represent
two forces acting on an object. The directions of the arrows show the
directions of the forces, and the lengths of the arrows represent the
strengths of the forces. Which answer choice shows an object being acted
upon by forces that do NOT add up to zero?

4. Item FM074005:
a. In the drawing below, the arrows labeled Force 1 and Force 2 represent two
forces acting on an object. The directions of the arrows show the directions of
the forces, and the lengths of the arrows represent the strengths of the forces.
i. Correct Answer
1. C
ii.
Misconceptions
1. Answer Choice: A
2. FMM115: Students add forces without considering the direction
of the forces, i.e., they add absolute values of the forces (AAAS
Project 2061, n.d.).
iii. Answer Choice: B
1. FMM116: When force arrows are used to represent opposing
forces, students think the greater force wins so that the total force
is equal to the value of the greater force (AAAS Project 2061,
n.d.).
iv. Answer Choice: D
1. FMM094: Two forces in opposite directions will cancel each
other no matter what their strengths are (diSessa, 1993).
