Gravity is the pulling force that the earth exerts on us all. It is the reason why we don’t fly off the earth as well. The gravity on the moon is very much less than that present on the earth. That is because gravity is dependent on the mass of the body. So it is easy for astronauts to jump big distances with small leaps on the moon.

In space there is no gravity at all. That is why when an astronaut comes out of his space craft he tends to float around with no direction to his drift. There is no wind in space to blow him around either. So he uses his own jet engines to propel himself around.

You don’t need to be out of this world to experience gravity, the lack of gravity and to have fun with it. Kids use gravity in games every day. Here’s a few things that they do. You might already be doing a few of these activities and not know that you were employing gravity. Or you may find a fun new game to play. Check it out and think up of more things that you can do with your friends.

Remember all objects exert some amount of gravity. The one which has a bigger mass will have a bigger gravitational force. That is why the sun pulls the planets around it and the planets can pull the satellites. In this case size does matter quite a bit.
