Unit 7 Blog Post #7

Today in the second day of unit 7, we reviewed momentum. We turned in our lab activity we did yesterday. Mr. Blake went over it answering questions about the lab activity. We did a physics momentum worksheet. We had to find the momentum of 2 bumper cars before and after they collide. The bumper cars collided in different ways, similar to the collisions in our lab activity yesterday. We then did a lab practical. The lab practical was similar to the lab activity we did yesterday. We got the carts lined up and attached them to each other by the pins. We then got a dart gun and shot sail on top of the cart. This  pushed the cart forward through the photogate. We did that five times and found the average. Right before lunch, we did a water balloon activity. Sparks and I gently threw a water ballon to each other slowly getting farther away. After lunch, we reviewed more momentum problems preparing for the test we have tomorrow. Then we got together with our group to discuss our egg project.

In this picture, Gio, Sparks, and I are doing our lab practical. The momentum of the bullet pushed the carts to pass through the photogate.
