🟢 8: W 2/11 - ↩️ Pivot ballistic pendulum lab
Today, we'll look at another lab in ↩️ Pivot Interactives called "Ballistic Simple Pendulum Challenge." This is a classic physics problem which will give us the opportunity to think through the different problem solving methods we have learned in this class up until this point. Traditionally, ballistic pendulums are used to measure the velocity of fast-moving projectiles such as bullets. After making measurements using a model, we will explore the differences between the expected and actual results. We'll have some time next class to finish this lab.
Homework: QUIZ on Impulse and Momentum in 1-D next class - Thursday, February 12th. Ballistic Pendulum Lab Quiz on Friday, February 20th. Finish the ↩️ Pivot lab by Thursday, February 19th at 10pm. Remember, no late work accepted in ↩️ Pivot.
🟩❗8: Th 2/12 - momentum in two dimensions
🟩❗8: Th 2/12 - momentum in two dimensions
QUIZ on Impulse and Momentum in 1-D TODAY!
Today, we'll remember that momentum is a vector and discuss momentum problems in two-dimensions. The discussion will brief and touch upon our previous experience with two-dimensional vectors. We'll do the first problem from this Momentum 2-D presentation.
Then, we'll do problem solving involving 2-D collisions.
Homework: No Homework Weekend. Finish the ↩️ Ballistic Pendulum Pivot lab by Thursday, February 19th at 10pm. Remember, no late work accepted in ↩️ Pivot. Ballistic Pendulum Lab Quiz on Friday, February 20th. Momentum Unit Assessment on Monday, February 23rd.
Optional extra practice: 📖 textbook collision problems: #35, 39, 63. , pages 2 and 3 in Momentum Packet. (SOLUTIONS to Cons Momentum CompuSheet & SOLUTIONS to Momentum Practice Problems p 3)
Here's a really good video showing the full calculations involved in a complex 2-D collision:
💚 8: W 2/18 - create a momentum and energy problem
💚 8: W 2/18 - create a momentum and energy problem
Today, now that you've already done some problem solving, you will collaboratively come up with your own problem with a scoring guide. The problem should involve both energy and momentum. You'll create a detailed scoring guide for the problem you create. The problem with scoring guide is due by the end of the period.
