material problems

Say I have an object Such as a shpere,and a plane as the ground.When I add I add materials to the the sphere, evrything is fine but if i add materials to the ground and push “P”,the ball wont bounce…HELP!!! please.

For the plane; go to shading (F5) then on the right, click the Material Buttons. In the materials tab there should be a little button named “DYN”, click it and in the settings that come up set restitution to a higher level.

The higher the restitution for the plane, the higher your ball will bounce.

I dont understand this one

“shpere” is it?

hmmm…
