Can anyone recommend a good set of gears that can be used in my high
school
Physics/Advanced Physics classes? I'm looking for something that is
durable
and can be easily interchanged to see the effects of the different
arrangements.
Have you considered bringing a 21-speed bicycle to class?
Bicycle gears meet the definition of gears, and they can
be easily interchanged.....
Also the relevance to students' lives is pretty obvious.
