i dont mean to open a physic class here but to enquire any available, i mean tested planet simulation
So that a 500g basket ball can bounce like it suppose to be, a 3kg stone will not bounce, and a 1kg wooden box can bounce but not as high as the basket ball
It depends not only on gravity and mass, but also on the properties of the bodies. I.e. a 500g basket ball bounces, but a 500g stone doesn't.
I'm not much into Box2D but I think you can apply a force to make e.g. a basket ball bounce in a collision callback?
For modelling a basketball, it's easier to just give its shape a high restitution. It will make the ball "bouncy" without having to use collision callbacks at all.
