We started off class with Mr manning hanging back papers such as daily questions, the previous lab we did or collisions, and he handed back the quizzes that we took yesterday. We then went over the quiz and answered questions on how to do some of the problems. Mr manning gave us the room number that we will be taking our midterm in. Which is room 128 for period 7.

We then were given the rest of the class to work on the review packet that goes along with the midterm next Thursday, 3rd block. The review guide goes over all of the following information. It starts with a sample problem where you need to give the application of Newtons 3 laws of motion in the problem and describe why it uses that law. There is a graph with a line of best fit and you need to explain the meaning of the slope and of the y intercept. Also, he has you write it into a word equation and use it to answer a question. You need to be able to describe XT, VT, FT, and AT graphs and explain what it tells you and also what its bounded area is telling you. You need to be able to draw free body diagrams and explain all the forces acting on them. There's also a lot of problems dealing with the equations that are on your orange equation sheet or on your physics t-shirt. The review guide is not required to be finished but is recommended to ensure you know the information for the test.

The picture is an example of an XT graph, which will be on the test. This graph has a positive position, a constant speed, and a negative direction
