Tuesday 5/4/21
students are took Unit 4 Exam
watch this video developing the concept of conservation of momentum
watch this video for homework showing how to use the mass-velocity block (momentum charts) to solve problems
work Unit 5H Momentum/Impulse Practice 1 . Upload a scan/pic of your work to Google Classroom. If you have questions about how to do the assignment after watching the video, ask them in the Google Classroom thread.
Today's Recording
Wednesday 5/5/21
discussed solutions to Unit 5H Momentum/Impulse Practice 1
discussed a different approach to solving the same problems from Unit 5H Momentum/Impulse Practice 1
Thursday 5/6/21
held nominations for the momentum unit - pooballs was selected as a unit for momentum
worked multiple examples of momentum conservation problems using both the mass-velocity method and the equation method
discussed what would happen if we only choose one of the two objects colliding as our system (momentum is not conserved...change in momentum brought about because of an external force from the other object!)
Friday 5/7/21
reviewed what would happen if we only choose one of the two objects colliding as our system (momentum is not conserved...change in momentum brought about because of an external force from the other object!)...impulse causes change in momentum
discussed various examples of impulse=change in momentum
Monday 5/10/21
projectile warmup with finding vf and pf at bottom of flight from horizontal cliff launch
introduced conservation of momentum in 2D
Tuesday 5/11/21
vertical launch from edge of cliff warmup...find p_bot
completed 3rd example of conservation of momentum in 2D
general unit review
students worked on MasteringPhysics 7s
Wednesday 5/12/21
students take momentum test today
