## Main Question or Discussion Point

I was wondering, since i've heard it said so many times. They space probes use gravitational slingshots. Okay, I get it, a probe goes around a planet or something, and when it goes around the other side, its faster right? Well...how exactly does it work?

1: How does a Gravitational Slingshot work?

2: How much faster does the slingshot make the object?

3: Does the object go on at the speed the slingshot gives it forever? (In space, i thought you never slow down since there is no friction.)

4: Is there some mathematical formula for this? If so, what is it? thanks!

5: anything else you can tell me about it helpful? ANYTHING about gravitational slingshots really will help!
