🟢 5: M 2/26 - momentum review
Today, we'll have a review day for momentum. You may work on 📖 Mastering Physics problems due soon and find additional problems to study for the next unit assessment.
Optional extra practice: pages 2 and 3 in Momentum Packet. (SOLUTIONS to Cons Momentum CompuSheet & SOLUTIONS to Momentum Practice Problems p 3)
Optional Grade Insurance: Two optional opportunities to raise your grade are below. Both assignments are due on Wednesday, February 28th Friday, March 1st at 10pm, ABSOLUTELY no late work on these extra assignments, no exceptions. ABSOLUTELY NO LATE WORK WILL BE ACCEPTED.
Optionally try some more advanced 2-D momentum problems in this OPTIONAL 📖 Mastering Physics "Extra Credit - Ch 9 - 2-D Collisions" problems: #38, 73 (plus colliding balls problem).
For an additional good grade in the lab category, complete this optional lab in ↩️ Pivot Interactives called "2D Collisions." Only complete and good quality submissions will receive the extra grade.
Homework: 📖 Mastering Physics "Ch 9 - 2-D Collisions" due tomorrow at 10pm. Study for Unit Assessment on Work, Energy, & Momentum on Thursday, February 29th Monday, March 4th. We'll start the next unit before then.
🟩 5: T 2/27 - explosion lab (1)
Today, we'll be exploring the conservation of momentum in explosions. We will try to determine the outcome of a (very safe) "explosion" of two carts in an in-person verification activity. The lab has two parts:
In the first set-up, two carts of different known masses are placed touching each other on a track. When you push a button on one of the carts, they will explode apart from each other. You must figure out where on the track to place the carts so that they reach opposite ends of the track at the exact same time. After doing the calculation, you'll perform the experiment to verify your results.
In the second set-up, you'll use a similar set-up to determine the unknown mass of a bag of sand.
If you are absent, email me to ask me to open up the make-up in ↩️ Pivot Interactives called "Exploring Momentum and Impulse: Cart Push Off" which is due on Wednesday, February 28th Friday, March 1st at 10pm for anyone who was absent on Tuesday.
Homework: New policy - no late work will be accepted after the unit assessment. Very neatly write up your solutions to the first part of the lab for in-person submission at the beginning of class on Friday, March 1st. Unit Assessment on Work, Energy, & Momentum on Thursday, February 29th Monday, March 4th. We'll start the next unit before then.
