2. On Earth, gravity affects everything we do. We can’t predict how our usual objects will react in space.That’s why NASA did a project called ” Toys in space “ and we’ll show you how these toys reacted Anton Madalina si Balaita MaraColegiul National

3. Gravity:On earth,every toy is affected to some extent by the pull of gravity Gravity:On earth,every toy is affected to some extent by the pull of gravity Energy conservation:Every object has Kinetic Energy.An astronaut trying to move a toy in space must find a source for the energy needed by the toy Energy conservation:Every object has Kinetic Energy.An astronaut trying to move a toy in space must find a source for the energy needed by the toy Anton Madalina si Balaita MaraColegiul National

4. Microgravity:In space toys experience “weightlesness” or “zero gravity” Microgravity:In space toys experience “weightlesness” or “zero gravity” Momentum conservation:Objects in action have momentun.In a collision,momentum is conserved.When one object loses momentum another one has to gain it Momentum conservation:Objects in action have momentun.In a collision,momentum is conserved.When one object loses momentum another one has to gain it Anton Madalina si Balaita MaraColegiul National

5. Inertia:Objects in motion tend to stay in motion and objects at rest tend to stay at rest.An astronaut must exert a force to cause a toy to change its motion. Inertia:Objects in motion tend to stay in motion and objects at rest tend to stay at rest.An astronaut must exert a force to cause a toy to change its motion.

9. Anton Madalina si Balaita MaraColegiul National In space, the yoyo will not sleep because there is no force to stop it. If the string is Released on the way out, the yoyo will wind up its string while moving forward.

10. Anton Madalina si Balaita MaraColegiul National 1.They stick and begin to spin around their joining points 2.We push another marbel into the chain 3.The whole chain will oscilate 4.If enough marbles are added,the chain will move so wildly that the two ends make a circle

11. In space the “Rat Stuff” could not stay on the wall long enough to work.Astronauts had to use hand cream in order to make the toy sticky enough to work properly. Anton Madalina si Balaita MaraColegiul National

12. Magnetism is the same in space as it is on Earth,so the wheel does stick to the track.By slinging the wheel sideways in a circular arc the wheel starts by using a combination of inertia and centripetal force Anton Madalina si Balaita MaraColegiul National
