It is now time to be sure we know how to do all the parts of the Rocket Project. We want to calculate not only its average velocity, but also its velocity on take off and impact. We would like to know its acceleration on take off, and thus the force on it. We would also like to make graphs of its motion.
First, we need to know a little bit about falling objects.
Watch this video HERE. Its a bit long (16 minutes) but after seeing it you will know how to calculate many of the things we need for our rocket, such as finding its height from the time it is in the air.
Take notes on the equations used, and be prepared to show them at the start of class.
Second, we'll be making graphs of motion. Check out THIS video. Then make your own graph of motion, and be prepared to show it at the start of class. Don't spend a great deal of time on this - a quick rough graph is fine. For example, you could graph the motion of your car when it drives out of your drive way - when does it speed up, slow down, stop? You can do position vs time or velocity vs time.
Good job! We'll be working on the Rocket project in class. Remember that you are still responsible for keeping up the reading, one section at a time.
