1/28 Physics Class update and homework due 2/5

Hi folks,

Today we took a look at the concept of impulse.  Impulse is what causes momentum to change.  We also did a lab today where we found out how much impulse a device imparted on a Hot Wheels car.  

Also for homework this week is a scavenger hunt.  I want you to find two examples of all the concepts written below.  So 14 pictures in total.

Rules:

They must all be different.   

They must all be photos you have taken with a camera (not images from the internet).

They can be things that you just come across or you can set up situations that exemplify the concept.

Write a sentence for each one indicating why that photo is an example.

Videos are allowed if you wish.

You can print out the photos to hand in or you can email them to me.

1.  Newton's First Law

2.  Newton's Second Law

3.  Newton's Third Law

4.  Momentum

5.  Impulse

6.  Acceleration

7. Inertia


Also, answer the following questions regarding today's lab

1.  What procedures did you use to find the impulse of the Hot Wheels car shooter thing?  Please describe the steps you took.  The measurements you took. And the calculations you did.

2.  Since we were looking for impulse of the device, and impulse is Ft, why didn't we measure force or time of the device?


3.  What procedure did you follow to calculate/predict the velocity of the car with the extra mass?


4.  Since mass increased during the second set of trials, what did you expect velocity to do?


5.  Take a look at this experiment in terms of Newton's second law
  1. What is the force, the mass and the acceleration here?  
  2. How would the change of mass affect the acceleration?  
  3. What do the three settings have to do with Newton's second law?

4/29 Physics update and homework due 5/6

Hi folks, Today we took a bit of a deeper look into light and began our unit on optics.  We will do more with optics next week. For homework this week…I've changed my mind.  :) Remember that extra credit assignment I was talking about in class, well let's make it homework with extra credit possibilities.   Here's the scoop.  Take a look at this article by Randal Monroe from his What If blog.    https://what-if.xkcd.com/3/   You'll see how he uses different physics concepts and applies them to real world things even though the situation is fictional.  (Unless somewhere out there Yoda really is hanging out on some swamp planet…it's possible.)   Now you do it.  Pick any book, movie, comic or video game and apply some of the things we've learned this year.  I've included one of my ex-students papers for example.  It's very good be sure to take a look. For homework, Apply at least 5 different physics concepts to the situation. ...

Caerus Summer Mini-Class in July

Image
Hi everyone, I hope everyone is having a great summer.  I've been enjoying catching up on some reading and doing some much needed house/yardwork. Most of you are may already aware of the following free class but I'd like to invite you all personally.  If anyone would like to hang out with us next Saturday afternoon and enjoy a really fun class, we'd love to see you.  Also, please bring a friend!  Do you know anyone who might be interested in taking a fantastic English, Math, History or Science class?  If so, bring them along (or forward them this email….or both)!   Last but not least, we'd really appreciate it if you would take the time to pass this down any group lists of Facebook groups you may be on.  Here's the link to the website.   http://www.caerusacademy.com/free-july-mini-class.html Thanks again everyone.  Hope to see you next week!
