You are going to need a car and someone to drive you around (an empty parking lot would be good for most of this). Hang a washer or a spoon or something kind of heavy from the ceiling in your car with a piece of string, it must be able to swing freely (you can hold the string with your hand but your hand must be held up against the ceiling). Notice how the weight moves as the car moves. Pay particular attention to how far and in what direction the weight swings when you:
1) Maintain a steady speed that is slow.
2) Maintain a steady speed that is fast.
3) Start of from a stop with the weight not moving and then accelerate slowly.
4) Start of from a stop with the weight not moving and then accelerate quickly.
5) Maintain a steady speed with the weight not moving and then decelerate slowly
6) Maintain a steady speed with the weight not moving and then decelerate quickly
7) Maintain a steady speed with the weight not moving and then turn slowly.
8) Maintain a steady speed with the weight not moving and then turn quickly
Why do so many people get ejected from cars when they are in an accident and not wearing a seat belt?
Lab reports must include four parts: hypothesis (a statement of the specific things you expect to happen in the experiment), method (a detailed description of what you did), data & observations ( a detailed listing of what you saw, and an organized data table for any numerical data you collected), and Conclusions. The conclusions should state your major findings, discuss if what you found supported or did not support your hypothesis, and connect what you learned in lab to the topics studied in class that week. You must complete all parts of each lab and the lab write up for full credit. Each lab report is worth 20 points.
