Energy Homework

The homework can be located here.

I included some examples of open-ended questions.

Potential and Kinetic Energy

Here's the homework for today. This is due on Wednesday. There are no exceptions. Please do this on a separate sheet of paper. The questions are as follows:

1. 1. How much kinetic energy does a 4 Kg cat have while running at 9 m/s?
2. 2. What is the mass of an object moving with a speed of 4 m/s and a kinetic energy of 2000 J?
3. 3. A 400 Kg car has 1.8 x 10⁵ J of kinetic energy. How fast is it moving?
4. 4. How fast is a 3 Kg toy car with 20 J of kinetic energy moving?
5. 5. A student runs to physics class with a speed of 6 m/s. If the student has 880 J of kinetic energy, what is her mass?
6. 6. What is the speed of a 1200 kg car moving with a kinetic energy of 15 kJ

Energy Poster

A few of you said that the poster was helpful, so I've decided to post it up here.

Scientific Notation For Juniors and Freshman

For the next unit, you will need to know scientific notation. I have included a chapter from Physics Demystified for your reading pleasure. There are questions at the end of this chapter that will be assigned.

THE QUESTIONS ARE 6-9 ON PAGE 48!!! THEY ARE DUE FRIDAY FOR THE FRESHMAN AND MONDAY FOR THE JUNIORS!!!

IT'S FOUR MULTIPLE CHOICE QUESTIONS ON SCIENTIFIC NOTATION.

Junior Homework

Just a reminder:

THE LAST DAY TO MAKE UP ANYTHING IS THIS TUESDAY!!!

There is also a homework that is due on Tuesday. IT MUST BE IN TUESDAY!!!

Here's a link to it in case you weren't in or lost the sheet.

Tuesday, January 10th, 2012

Hey Ya'll.

Freshman Physics... Look over the "practice problems" worksheet Mr. Kolb gave out at the end of class today.  Do your best to complete it.  Remember that all retakes and make-ups must be completed by the latest Tuesday January 24th.  Your midterm will be on Monday January 30th.

AP... Linksssssssss! Magnetism Presentation (*.pdf), Magnetism Practice Problems, Magnet and Compass Simulation

The following is a video from Khan Academy talking about how we understand centripetal acceleration. Remember: Acceleration is a Change in Velocity. Velocity has magnitude and direction.

The following is a video we watched in class. It is important to understand why these demonstrations happen:

The solution to the classwork can be found here.

Uniform Circular Motion!!!

This week we are covering uniform circular motion. I will be handing out a worksheet here to use with the simulation below.

Click to Run

Some questions you should keep in mind are as follows:

What is the angular velocity of the ladybug?

What is the Linear / Tangential Velocity of the ladybug?

What is the acceleration of the ladybug?

You should also read this handout by clicking here. Pay close attention to the "Real-Life Applications" section.

The solutions for our classwork problem can be found here.

HOLIDAY BREAK HOME WORK!!!!!!!! JUST DO IT!!!

Hey everyone.. below you will see your assignments we EXPECT you to complete over the holiday break.  Its broken down by classes:

Freshman Physics:  This packet is a review of all the things we've covered so far, there is nothing new, it is just practice.  Complete all of the "example" parts.  It will count as a TEST grade and it must be turned in on Wednesday, January 4th. Winter Packet .  Also, here is a .pdf of the slide show we've been using in class UCM Slideshow

Junior/Senior Physics:  This packet is a review of all the things we've covered so far, there is nothing new, it is just practice.  Complete all of the "example" parts.  It will count as a TEST grade and it must be turned in on Tuesday, January 3rd. Winter Packet

AP Physics:  You know what you have to do... Here are the links. AP Winter Packet , AP Equation Sheet , Physics for Dummies , AP Electric Current and Circuits Chapter Presentation ,
AP Electric Current and Circuits Practice Problems , Khan Academy: Physics .  Sorry, I couldn't upload the textbook.  For those of you that have borrowed the text, use it!

New Policy Changes That Affect Everyone

Policy Changes - Starting After Break

1) In order to retake the test, you must show proof of studying. Proof of studying consists of:

a. A pre-test worksheet to be submitted prior to the test that day.

b. A pre-retake worksheet to be submitted prior to the retake that day.

2) Labs must be done on an individual basis. Everything must be typed with the exception of the calculations.

a. Procedure (Whatchadid)

b. Observation (Whatchasaw)

c. Calculations (Whatchadid with Whatchasaw)

d. Conclusion (Whatchalearned from Whatchadid with Whatchasaw)

3) Blogs

a. Blog posts must be done before the next class.

b. Starting January, blogs will be checked the day that they are due at 3:00pm.

c. The blogs must be written with attention to grammar, spelling, and clarity.

d. The rubric for blogs will be as follows:

i. Comprehension (15 points)

1. The student does not comprehend the blog assignment.

2. The student shows marginal comprehension of concepts.

3. The student shows comprehension of the subject.

4. The student shows mastery of the subject.

ii. Clarity (10 points)

1. The student was not coherent.

2. The student shows 1 or 2 disconnected ideas.

3. The student shows ideas but does so with disconnect.

4. The student’s ideas flow and are well-interconnected.

iii. Creativity (5 points)

1. The student plagiarized ideas from un-cited sources.

2. The student did not properly cite a source.

3. The student connected outside sources properly to the ideas expressed.

4. The student came up with original ideas based on the information.

Freshman Physics

We did a great activity on Tuesday involving dragging texts. This is what I want for Thursday:

1) Procedure (Whatchadid)

2) Observations (Whatchasaw)

3) Calculations (Whatchadid Wit Whatchasaw)

4) Conclusions (Whatchalearned From Whatchadid Wit Whatchasaw)

Write on your blog:

Explain Newton's 3 laws using original examples of events that occur during a typical school day at East Side.

 

This blog will be due on Monday, December 19th, 2011

 

Nerf Lab for the Freshman!!!

This is what I want you to write for your lab:

The Goals: You were trying to find out Muzzle Velocity and Force of Ejection. What are these?

1) What was your plan to figure out Muzzle Velocity and Force of Ejection? What was your procedure? Give me lots of details!!!

2) What did you find? Include your data!!! What was the Muzzle Velocity and the Force of Ejection? Which launcher was more powerful (i.e. the Force of Ejection was greater)? Which launcher has the greater Muzzle Velocity? If you only had time to test one launcher, give more details such as how the range is affected by the Muzzle Velocity.

This lab should be 2-3 pages (including your original data). Everyone should submit their own lab report! This is due on Monday!!!

AP Physics

AP Physics Blog Assignment:

This is all the physics you know thus far: kinematics, dynamics, momentum, & energetics. Your mission is to launch a projectile from the roof of East Side High School to Central Park in New York City. Explain how you would accomplish this. Also explain the difficulties in doing so. Could this replace the United States Postal Service? Why or why not?
