LÖVE

I'm trying to make a platform game.

Can anybody give me some example values for the gravity, object masses, etc. to give a world where objects can bounce off other objects?

I can't seem to figure it out, all the worlds I create are very slow, and objects only bounce very slightly.

make a test setup where the key values are changeable while it is running and then play with it until you get what you like.

earth's gravitational acceleration is about 9.8m/s or 32ft/s
trying making objects have very low mass
