Sorry my english is not too good

ok, so now do I tell the teacher she is teaching the class wrong or just let it go

Its not the actual physics class, but a physics unit in a regular science class. Also, i made some typos in my last post, which i edited; i meant to say air resistance instead of gravity. of course gravity has an effect inside a vacuum (:

one third of a football field is a little more than 88 ft. Also, the average running speed is about 20fps

I would say that force=mass x acceleration (not nessesarily the acceleration of gravity though) gravity accelerates objects at 9.8m/s/s one joule=one Newton/metre air resistance has an effect outside a vacuum

I am currently in eighth grade science, in a physics/energy unit. My teacher does not seem to know what she is doing, and I question her knowledge of what she is teaching. Here are some of the formulas and theories she insists are true: -force(N) =mass x 9.8m/s/s -The force gravity exerts...
