Today in class:
Video on acceleration
Video (mythbusters) on vector addition
We drew a motion map of a dropped object and used its position-time and velocity - time data to determine acceleration due to gravity ("g") on the Earth. We found a number of (-) 10m/s/s. We will be using this value in class since you can use it without a calculator, but the accepted value of acceleration due to gravity at Earth's surface is -9.81m/s/s.
I handed out a worksheet that is due on Thursday and gave time to work on it or to work on / ask questions on labs which are due tomorrow.
