2/19 AP: More momentum problems.
It looks like I’ll be back on Thursday. Still a rough throat, but the doc thinks I’ll be ready by then. I’ll probably have a wireless mic so I don’t have to strain my voice 😊 . You might also find these instruction helpful. I hope to post some videos…Read More
2/18 AP: Conservation of momentum book problems
Book reading/review Review 6.2 Conservation of Momentum, pages 166-168 Read 6.3 Collisions, pages 168-175 Pay particular attention to the Problem-Solving Strategy method described on page 173. Problems (pages 182-184) Remember that only when a collision is described as elastic can you use conservation of kinetic energy. 6.2 Conservation of momentum…Read More
2/13 AP: p and K spreadsheet calculations
Today you will finish your spreadsheet calculations. Remember, momentum is a vector, so some of your velocities will be negative. Be sure to include these, and that they match the relative directions of your carts. Start with one trial and: Use formulas in the spreadsheet to calculate p, K, Δ…Read More
2/12 AP: Final momentum lab day
OK, unless I get hit by a truck, I will be back on Thursday. Today, please work together to help all students complete their data collection and analysis Data analysis should include: Description of each type of collision/explosion you created. A list of the percent momentum and percent kinetic energy…Read More
2/11 AP: More on momentum
My lengthy illness (severe sore throat, doc says it’s not coronavirus, but I did get tested for strep today) has presented an opportunity that I have always wanted to do, but never had the nerve to go through with: Set a class to work on a topic and let them…Read More
2/10 AP: Momentum lab spreadsheet
Hi all. I’m out for another day or two (extreme sore throat, no, not caronavirus!) From the feedback I’ve received on Remind, it looks like most groups have completed, or are successful at gathering, the data. Please take Monday to complete gathering data and entering it into a spreadsheet. I’m…Read More
2/7 AP Phys: Analyzing data
Data collection Please finish data collection for both collisions an explosions. Remember that an explosion uses the spring on one cart, and both carts start with zero momentum. Data analysis Analyze all your trials, calculating the momentum and kinetic energy changes for each scenario. If you would like, you can…Read More
2/6 AP: Collecting momentum data
Your goal today is to collect pre- and post- collision data for both of your carts in four different variations (e.g. changing the mass, changing the velocity, changing the direction of the cars).
2/5 AP: Tips on Vernier photogates
Tips to support data collection for yesterday’s lab. Photogates The Vernier Photogates use a beam of light to detect objects between the two ‘arms.’ LoggerPro identifies the gate state as “Open” or “Closed.” Open implies that nothing is blocking the light beam Closed implies there is something blocking the light…Read More
2/4 AP: Impulse and momentum labs; 1 dimension
These labs will take about three days to complete. Tuesday will be preparing/practicing. Wednesday will be completing Part 2 and 3. Thursday will be sharing your trends/conclusions with the class, where we will look for overall trends/conclusions. Prelab discussion (much yesterday) Part 1: Qualitative construction of momentum Part 2: Collision…Read More
