There are two kinds of "overhead projectors"

Opaque and transparency.
The opaque is probably what you are thinking of. The ones schools use are quite large boxes (I used one at Theatre/Theater and Bindlestiff Studios to create billboards for productions)
There are smaller ones like the Artograph I got from Pearl that only handle 7x7 inch images.
I haven't been able to find the old-fashioned box-monsters online. All I can find are the modern compacts like the Buhl Mark IV Opus. A thousand dollars! Argh!
Try eBay and Google looking for Opaque Overhead Projector. Your local library may even rent them.
Hope this helps.

    I have done a survey and over 80% responded yes to the above question. In order to prove it, I need to use physics to prove it.

    I just want to know if you have any safe and suitable ideas which can allow students of the class to experiment this. I need to know the design of the experiment, variables, procedure and how and what will the graphs be?

    Thanking You

    • The most obvious way to increase speed would be to decrease air resistance- duck your head behind the wind shield , tuck you elbows in to your sides. As far as gravitational forces, your seating position would not change …cts for acceleration with different designs that reflect good and bad wind resistance. I know- set up a car racing track and attach different bonnets to the front of either car on the track and have them race each other.
