The total amount of momentum in a closed system is constant. Some examples of closed systems include: marbles colliding or two bumper cars bouncing off each other. Momentum is the mass of an object multiplied by its speed. If two cars collide, the momentum of the system (car one plus car two) is the same after collision as it was before collision. Each car might have a different speed after colliding, but the total momentum is the same, it does not increase or decrease. This is known as conservation of momentum.

Richard Garriott demonstrates how magnets act in space using two magnets to see if, in microgravity, they interact with each other the same way they do on the surface of the Earth; if magnetic forces act at a distance; and where do they point. Magnetism is one of the fundamental forces. A magnet is a material or an object that produces a magnetic field that extends out from a magnet and can exert a force at a distance. A compass uses a magnet that can spin easily and can be used to determine directions. The Earth has a magnetic field that caused it to act like a giant magnet.

i wonder what they do, when their not working up there, can they use the internet lol, or maybe they have like dvds or something, lol or gameboy!
cool videos. could be used as phisics lessons
I WANNA GO TO SPACE
I never thought about how the magnets would behave in a spacecraft, this is amazing to see. Thanks !
xD must be funny
I want to learn more about the Bermuda Triangle!!!! It must be fun in space 😉
OMG I Love to go there. It looks like he is doing magic.
there must be very intelligent people watching these vids
wow this is much better demonstration then what we did in school 😀
sooooooooooo cool!
Thanks for posting this 🙂
that looks like so much fun 🙁
