Hi folks, Today we spent time covering the new concept of momentum.  We also did a lab today where the students were able to see the effects of mass on momentum. Happy holidays everyone!!!!   For your first homework assignment of 2020, please do the following questions.  I've provided the answers in an attached pdf. 1.  What is the definition of momentum? 2.  How is momentum different than inertia? 3.  If something's mass increases does it's momentum get larger or smaller? 4.   If something's velocity decreases does it's momentum get larger or smaller? 5.  Which has more momentum, a squirrel traveling at 15 mph or a Honda traveling at 15 mph?  Why? 6.  Which has  more momentum, a bowling ball moving at 20 mph or a bowling ball moving at 5 mph?  Why? 7.  Which has more momentum a walrus or a penguin?  Why? 8.  In today's lab, what was the point of the car that just sat on the track? 9.  In today's lab, when y...

Hi folks, Today we wrapped up our unit on Newton's Laws by putting them to good use.  The students had a challenge this week to create the fastest balloon powered vehicle that they could.  It was quite a tricky challenge but everyone gave it a good shot and we saw some really nice designs.   For homework this week, I want you to think about the car that was made in class and write, at least, one sentence describing how the following physics concepts applied to your car.  (Some of the answers may seem redundant but I want to make sure you consider certain things about the balloon cars.) What did inertia have to do with your car? 2.  Apply Newton's second law to the car? (Be sure to use F, M and A in your answer.) 3.  Apply Newton's second law again, in a different way.   (Be sure to use F, M and A in your answer.) 4. What did mass have to do with the Ballon Car Challenge? 5. How did Newton's 3rd law relate to the baloon car? 6.  Name 3 places ...

Hi folks, Well, today we moved on from Newton's first and second law on to Newton's 3rd Law. For homework this week, I want you to watch  this video    It's a video of amazing people doing amazing (and perhaps ridiculous) stunts.   While you are watching the video, I want you to keep your mind on physics.  There are a ton of great examples of the concepts we've been working on these past few weeks.  I've listed many of the concepts we've been working on below.  What I want you to do is watch the video and list the best examples you can find of these concepts.  Please give a short description of what's happening in the video and why it's a good example of the concept.  I'll do the first one for you to get you going.  1.  Gravity:  Example: the folks jumping off the building.   It's a good example because gravity pulls them down.  Without gravity they would just sit there in mid-air and it wouldn't be much of a stunt. ...
