Todays class was basically a review of what we did on Friday. We started off by doing the questions out of the text book which asked us to find the displacement and velocity of different graphs.
- Displacement- find the area of the graph by using either 1/2bh (triangle) or lw (rectangle). Once you find the area add them together and that will give you the total dispacement. Remember if the graph has changed direction (gone below the x- axis) the area has to be subtracted.
- Velocity- finding the velocity of a specific point can simply be read off the graph. To find the velocity between two points you must first find the displacement or area of the graph, than by dividing that answer by the amount of time between the points it will give you the velocity.
Lastly after we were all finished the questions from the text book we were to complete the Assignment 4 Handout which was based upon the same types of questions.
