Week 8

This week we took a look at unbalanced forces. We took 3 masses of the same weight and balanced them on a table. 2 masses were hanging off the edge of the table and when we let go of the third weight, we were asked, what direction will the string pull when we let go of the third weight. We also looked at center of mass. We did multiple experiments to do this. We took 4 people, sat them in chairs to see if they would balance. They laid on each others knees and we pulled away the chairs and all of them balanced. It was pretty cool. We also looked at when picking up a chair. We did it first without being against the wall.Then we tried it against the wall and it was much harder to pick up the chair. Another experiment we tried was moving our legs, when against the wall, we could not balance ourselves.Also we tried picking up a pencil and we could not do it while against the wall. All of these experiments had a purpose and that purpose is to see what effects the way we do things and why does our center of mass change
