A question About Gravity

Hi,
I have a few problems with gravity. When the actor jumps and lands on the floor it just keeps on bouncing up and down. When your in midair and hit the side arrows, the actor just fly's in the air. Also when the actor goes to the top of the scene and goes off the scene it appears on the bottom. How do I fix all those problems?
Thanks
