Week 5: Universal Gravity, 2-D kinematics
Day 1: 2D mechanics (no trig).
Before class
- Do PS #4, on main website – First Question is Revision of MT#1 (answers and comments are posted on main website). But it’s not due until Tuesday, tomorrow. I added a last question about the string breaking ball.
- It is a good idea to read through the problem set before seeing the videos so you know where the information
- See the video on 2D work
- See video on 2D momentum transfer
- Read 3.6 and see video: Boat on the River Problem Solution Explained
- PS#5 is posted. It is due next Monday.
In Class
- Talk about projects – Project proposal due by midnight this Friday, April 29.
- PS #4 due
After Class
Day 2: (Inclined Plane)
Before class
- Finish PERFECT MT#1.
- See this video on estimating vector components again if you like. It was assigned for last Thursday, but is worth looking at again (in my opinion).
- See this video about the mass on the inclined plane
- See this video of work on an inclined plane.
In Class
- MT#1 corrections Due
After Class
Day 3:
Before class
- I wrote up solutions for MT#1. Please check them out on the main page.
- See video on Universal Gravity and Inverse Square Law
- Veritassium music gravity video
- See video on Inclined Plane using Only Energy (no kinematics at all!)
- From Textbook: Read the first half of section 6.5, up to (but not including) example 6.6
- I added a question to PS #5 (posted on main website), so there are 6 questions now.
In Class:
Big Exam #3
Get Feedback Cards for Tomorrow
After Class
Day 4: (Universal Gravity)
Integrate force to find potential energy for gravitational potential energy (graphs).
Use Conservation of energy in order to find velocity at different distances from a planet.
Before class
- Veritassium about Newton’s 3rd and gravity
- Escape Velocity
- Gravitational Potential Energy Graphs
- Fill out feedback cards for class.
- By midnight this Friday, your group will post a proposal for the group video project. The link is on the main webpage
After Class
Please see updated problem set including today’s class work due Monday.
