Re: Pushing a car uphill



Bath scale -- that's smart. I was going to suggest attaching a scale, etc. to a
strong (exact physical description) spring and pull. Is there a difference in
the perception between pulling and pushing for this experiment?

(The change in momentum is greater, so one might expect the task to seem
harder to do.)

I suspect that you (and the guys) are exerting about the same FORCE
but for differing amounts of TIME in the two situations. Exerting the
same force is often taken to mean 'just as easy'.

Get a set of bathroom spring scales to help quantify the force. And
use a stopwatch to get a handle on the delta t.

Let us know the results.
