RIGID BODY PHYSICS
This is used in Blender to have objects bounce off one another without deforming. Select an object, go to the Physics Properties tab within the Properties panel and select the Rigid Body button. Do this for any objects that are to collide within the scene. By default, all objects with Rigid Body Physics applied to them will fall under gravity. To view this, simply tap the space bar to begin the animation. Opening the Timeline panel allows for this playback to be manually controlled. To have an object interact but not fall under gravity, change its Type from Active to Passive within the Physics Properties tab.
BOUNCINESS
The Surface Response section contains a Bounciness value. For Bounciness to have an effect on the interaction between two objects it needs to be added to both objects.
ROTATION
A collision can also be dramatically altered by the orientation of objects relative to one another. To change the rotation of a selected object, press the R key, move the mouse and press the mouse button to commit the change.
