Physics Unit 4

So, we started Unit 4 today, and we started off with learning how to use the DAT, VAT, and VAD graphs on objects that are moving both up or down and left and right. In other words, we are learning how to use the equations on stuff that is either being thrown or dropped. The idea of graphing two different things at once was a really terrifying idea for me, but now, while it is still very terrifying, using the equations on them isn't as difficult as I thought it would be.

We had a lab today which involved shooting a little plastic ball out of the object in the picture above. The reason for this lab was to practice solving for the two equations on both distance and height, since the ball was moving forward and down at the same time. This lab along with all the other practice problems that we had were really helpful and I gained a stronger understanding of what to do. Unfortunately, while my group's lab practice wasn't very accurate, we were very precise and hit the same area every time we tried shooting the ball.
