force week

This week in science we talked about force. force is a push or a pull on an object. so when an object holds up another, the force would be the earth pulling on the frame, and the nail holding up the frame.
We learned this just from experimenting and drwing force diagrams. We drew on the white board and different hypothesises to our experiments we drew out. we knew it was the earths force and not gravity.
these ideas are used in real life because, astronauts dont float all the way to earth because of its pukl when theyre on the moon, the moon just pulls them in. Also when the atsrounauts come close enough to the earths atmosphere the force pulls them in because there is nothing to hold them up, unless they are leaving earth with there rockets puling them out.
