bicycle gears and going uphill
Posted: Sat Feb 02, 2019 9:29 am
My daughter's in the 3rd grade and we're trying to put together a science project that involves gears and going uphill.
Does anyone have a resource that could conceptually and graphically help her/us describe why it's easier to go uphill on a lower gear? All of the research we've come across seems a bit too mathematically and physics advanced.
I think we're going to do a variation on the jack and jill project that is listed under the project ideas.
I believe the hypothesis is that with the same force, the energy output to go uphill on a lower gear is less than on a higher gear??? Are we on the right track?
Help??? And thanks.
