Situation 10

The slider moves to the right and its velocity is decreasing linearly
(constant acceleration)

Result:

Correct Newtonian answer (B): 10%
Correct Aristotelian answer (E): 17% or
(G): 48% (322 students)
Comment:

An interesting result.1. It shows again that a decreasing velocity seems to be more difficult to explain than an increasing one.
2. The dominance of G answers demonstrates, how much the two terms, velocity and driving force, are interrelated for our students. A decreasing positive velocity seems to need a decreasing but positive force and not just a decreasing force which is negative from the beginning.
