## Chapter 11 - Vibrations and Waves release announcement

Giancoli Chapter 11 has been released! Waves and Vibrations are explained.

In this chapter you will find 3 hours and 4 minutes of videos giving answers to all your waves and vibrations physics questions (for the 6th Edition only, at the moment). Improve your grades and solve questions like a physicist with the techniques in these videos.

For the next little while I will be finishing the partially completed chapters, starting with chapter 7, then 9, and on to 18 and 19. After that I'll take a look at the chapter survey to see which one I should complete next.

## Chapter 10 has been released!

Fluids explained

In this chapter you will find 3 hours and 28 minutes of videos giving answers to the Giancoli fluids questions. Improve your grades and solve questions like a physicist with the techniques in these videos.

The photo for this chapter is of a water town in Johannesburg, South Aftrica. With Bernoulli's Equation you can calculate the required height of this tower to get a certain flow rate of water from a household faucet.

In the new year I'll be releasing many more chapters, and in the mean time, Happy Holidays!

## Rotational Motion Explained

Chapter 8 has been released!

In this chapter you will find 4 hours and 7 minutes of videos giving answers to all your rotational motion questions. Improve your grades and solve questions like a physicist with the techniques in these videos.

6th Edition focus

It's good news for most of you, but not-so-good news for 5th Edition user: I've decided to increase the speed of releasing chapters by focusing my efforts on the 6th Edition. The next chapter will have solutions posted only for the 6th Edition, and when all the 6th Edition chapters are complete, I'll come back to the 5th Edition if there's enough requests for it. I believe that a complete solution manual for most students is better than an incomplete solution manual for everyone. :) I apologize to the 5th Edition users, and rest assured this decision was not taken lightly, but the release process is slowed considerably by supporting two editions.

## Chapter 4 is complete

Newton's Laws explained! This is a challenging unit in your physics classes, but here you will find thorough answers to your questions. The 6th Edition alone has 4 hours and 30 min of video explaining all the Giancoli problems, and we also have all the solutions for the 5th Edition. Improve your grades and solve questions like a physicist with the techniques in these videos.

## October 2010 and Chapter 4

We're very happy to announce the release of Chapter 2 - Kinematics in One Dimension. If you have any questions about velocity or acceleration along a straight line, you'll find the answers in our solutions to Chapter 2. Check it out!

The next chapter I'm working on is Chapter 4 - Force and Motion: Dynamics.

## Sept. 2010 and chapter 2 is coming

Hello Everyone, I hope your new school year is off to a great start! At Checkmark Media, we're very happy about recent site updates that make it easier to subscribe to the specific chapters you need help with.

Currently I'm working on Chapter 2: Describing Motion: Kinematics in One Dimension so stay tuned for the announcement of its release.

## Rebuilt UBC website and created videos

I recently finished rebuilding UBC's Physics and Astronomy website C21 Physics Teaching for the 21st Century. This site is a resource for science teachers that illustrates connections between in-class concepts and real world examples. I also created three videos showing how to use a spreadsheet to simulate data with error, make a best fit line visually, and use chi-square analysis to fit data. This is a great resource for anyone with an interest in real-world science!

## Working with UBC Physics for teaching in the 21st century

Until the middle of June, updates on Checkmark Media will be slower as we are working with the UBC Physics department to add videos to their excellent wesite: Physics Teaching for the 21st Century. Check it out for in depth analysis of real world physics problems, like how does the efficiency of driving compare with cycling (and what if you take into account the energy used by a cyclist for their extra shower?).

## Solutions for Chapter 18

At long last we've posted solutions for another Chapter! Between having the Olympics here in Vancouver, and then leading a group of students to El Salvador during Spring Break to help build a house with Habitat for Humanity, it's been hard to find time to post solutions. In order to speed up the release of different chapters, I'm posting only selected problems from the sections we're covering in my classes. Chapters 19 to 21 will be the next chapters we cover, then we'll do chapters 2 to 4, and then we'll look at the results of the Chapter Survey to see which ones should be covered next. We'll focus on the even numbered questions at first and then after the popular chapters are finished, go back and fill in some of the gaps.
