Unit 7 Part 2

In class today we had a lab which was super awesome and we also learned more about momentum which was quite interesting. We also learned how more in depth about the Conservation of Momentum Law. This law basically states that momentum never disappears it is always transferred when colliding. This law was proven not only in our lab today but also when Cam and Mr Blake were passing the ball around on the reduced friction and zero friction surfaces.

In the lab what we needed was one air track which two carts that would be attacked would sit on. These two carts both had a sail thing at the top. What we had to do was shoot one sail with a nerf dart and measure the velocity of the carts. Record all the data and then use that data to help us solve a number of equations. I thought the carts wouldn't move but surprisingly they actually did move pretty quick, the quickest one moved at 0.54 m/s.

The second example was when Cam and Mr Blake were throwing the ball at each other. As you could see when Cam through the ball momentum from the ball going forward also caused him to go backwards. Same with Mr Blake when he caught the ball he went flying backwards because of the momentum pushing.
