pHeT 8.7

Investigate collisions on an air hockey table. Set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum

conserved? Is kinetic energy conserved? Vary the elasticity and see what happens.

I cannot open this PHeT, my computer just says Unidentified Developer, cannot open this file.

What do you suggest I do? Thanks so much!

I just opened the document and it works fine on my computer. Your computer should give you the option to override its decision to not open the file, but it appears that it isn't giving you the option.

You can skip this exercise, though it might be beneficial for you. You could try it on a public computer on campus, when the opportunity arises.
