This Week in Physics
For Monday please finish assignment 3. We’ll go over this and do our goal packets on Monday in class. For Tuesday please take notes on PODCAST 4: Power. We go over this and will then do assignment 4 together in class. On the day after we do assignment 4 we will take a quiz over the topics of power and the law of conservation of mechanical energy. This quiz will be worth twice the points of a normal quiz. Finally we will complete the Conservation of Energy Lab. Next up? Momentum!
Cool Science of the Week
Or, rather, hot science of the week. Scientists this past week released 2016 climate data that shows that, once again, we’ve set another record for the hottest year ever. The global average temperature last year was 1.7 degrees Fahrenheit higher than the average for the entire 20th century, and in some locales (notably near the poles) this average was around four degrees higher! Obviously this results in melted sea ice, which has reached its lowest values in thousands of years. (Melting sea ice is a major topic that we should dive into another time! Check out 2017 compared to 2016 in the second graph below!)
