Also we learned about sound waves (not part of the e-m spectrum) We reasoned that sound travels much slower than light. _________________________________________________________________________________________________ Homework: (Due Wednesday, 11.11.09) 1. Read and take notes on section 1.3 in the text. 2. Go to the Teacherweb home page, click of the Quiz 4w icon, use the password: energyquiz4w, and submit your answers. ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 11.11.09 Day: Wednesday _____________________ In Class today we discussed the speed of sound waves. We were given that sound travels at a speed of 343 m/sec in room temperature air. We then converted this to 0.21 mi/sec (or about 1/5 mi/sec) We also realized that this is equivalent to 1mi/5 sec Obviously, sound travels much slower than light. The speed of light (in a vacuum) is 186,000 mi/sec This explains why you see an event before you hear it. _________________________________________________________________________________________________ Homework: (Due Wednesday, 11.11.09) 1. Answer questions # 1 - 19 on page 31 in the Waves, Sound, and Light textbook. 2. If you haven't already done so, go to the Teacherweb home page, click of the Energy Quiz 4w icon, use the password: energyquiz4w, and submit your answers. ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 11.12.09 Day: Thursday _____________________ In class today, we discussed and modeled transverse and longitudinal waves We also discussed and modeled sound waves using an air blaster toy. We reasoned that sound waves are longitudinal waves. Mechanical waves require a medium through which to travel. Electromagnetic waves do not require a medium - they can propagate through empty space. _________________________________________________________________________________________________ Homework: (Due Friday, 11.13.09) Take and submit the online quiz, "Wave quiz 1w", on teacherweb (password: quizroom201) ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 11.23.09 Day: Monday _____________________ In class today, we 1. Discussed Newton's First Law of Motion 2. We learned the DOF/SSA protocol to solve physics problems 3. We calculated the average velocity of a car rolling down a ramp 4. We calculated the final (maximum) velocity of the car _________________________________________________________________________________________________ Homework: (Due Tuesday, 11.24.09) In 'Motion and Forces" Textbook, Page 55, questions # 1 - 6 ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 11.30.09 Day: Monday _____________________ In class today, we 1. Discussed Newton's First Law of Motion 2. Discussed Newton's 2nd Law of Motion 3. We learned the real definition of acceleration (and role-played speedometers) 4. We learned 3 different ways to accelerate _________________________________________________________________________________________________ Homework: (Due Tuesday, 12.1.09) In 'Motion and Forces" Textbook, Page 61, questions # 4 - 6 ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 12.3.09 Day: Thursday _____________________ In class today, we 1. Discussed Newton's 2nd Law of Motion 2. We learned that if there is no (net) force, there is no acceleration. 3. We learned that if there is a (net) force, there is an acceleration. _________________________________________________________________________________________________ Homework: (Due Friday, 12.4.09) Complete the "Ice Guy" worksheet. ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 12.4.09 Day: Friday _____________________ In class today, we discussed your solutions to 'The Ice Guy Dilemma" Your solutions included: 1. Walking off the ice 2. Crawling 3. scooting 4. rolling 5. falling and sliding 6. jumping and sliding 7. Ice skating 8. spitting 9. strongly exhaling 10. swimming in the air 11. Stepping on the coins and walking 12. digging the coins into the ice and pulling himself forward 13. putting one foot into the bag and walking 14. sliding on the bag 15. reflecting the sun off the gold coins to signal the helicopter 16. swinging the bag overhead 17. swinging the bag in a vertical plane (like a propeller) 18. swinging the bag back and forth 19. throwing the bag and holding 20. throwing the bag and letting go ________________________________________________________________________________________________ Homework: (Due Monday, 12.7.09) Look up or discuss the word, "Momentum" ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 12.7.09 Day: Monday _____________________ In class today, we continued our discussion of whether the Ice Guy should throw his bag of coins (and let go) so he will be accelerated backward or hold on to the string so the bag will pull him forward. _________________________________________________________________________________________________ Homework: (Due Tuesday, 12.8.09) Complete the Momentum worksheet ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 12.8.09 Day: Tuesday _____________________ In class today, we observed a skate-boarder simulating the ice guy throwing the bag of coins and then throwing the coins and letting go. We then explored the concept of momentum. We performed several calculations involving momentum including a collision. _________________________________________________________________________________________________ Homework: (Due Wednesday, 12.9.09) Complete the "Ice Guy Dilemma" worksheet. ________________________________________________________________________________________________ _________________________________________________________________________________________________ Date: 12.14.09 Day: Monday _____________________ In class today, (Periods 1 and 2) we discussed Newton's 3rd Law of "action and reaction forces" the took the assessment quiz on Newton's Laws and Momentum. In periods 5 -7, we discussed the concept of gravity and began working on the formula for the force of gravity. _________________________________________________________________________________________________ Homework: (Due Tuesday, 12.15.09) Pick someone in the class and SPECULATE as to the force of gravitational attraction you experience due to their mass. Express your speculation in units of lbs.
