Giancoli Solutions on Video

Learn physics easily with guided practice.

7th Edition Solutions 6th Edition Solutions Global Edition Solutions


  • 1,930 video solutions for all regular problems in Giancoli's 7th Edition and 1,681 solutions for most regular problems in the 6th Edition.
  • Final answer provided in text form for quick reference above each video, and formatted nicely as an equation, like $E=mc^2$. This is useful if you are in the library or have a slow internet connection.

  • Pen colors make the step-by-step solutions clear. Red is used to illustrate algebra steps, and to substitute numeric values in the final step of a solution. When a solution switches to a new train of thought a different pen color emphasizes the switch, so that solutions are very methodical and organized.
  • Solutions are classroom tested, and created by an experienced physics teacher.
  • Videos are delivered with a high performance content delivery network. No waiting for videos to load or buffer.
  • Pause, rewind, repeat, and never miss what is being said.

Mr. Dychko, your answers and videos helped raise my grade from failing to a B and I really appreciate your website for that. Physics does not come naturally to me by any means and to be able to use your website to pass my class means more to me than words can describe. Chegg wasn't sufficient and my professor wasn't available for extra help, so I consider your website to be the sole reason I passed my class. Thank you.

The videos were extremely helpful. You can play them over and over and pause them to review. The narrator explained the steps beautifully and provided details on performing the algebraic manipulations. Different colored pens made it easy to differentiate steps. My Physics teacher often moved through the material very fast in class. The videos allowed me to review areas I found difficult as many times as I needed. Giancoli Answers was a wonderful learning tool for understanding Physics.

Hello Mr Dychkko,

You are absolutely incredible!! Thank you immensely for sharing your wealth of knowledge with the rest of the world. Your videos have helped me get through physics in college, and I could not have passed my classes without you. Your step-by-step explanations were always so easy to follow, and helped me understand why we would go about a question a certain way. Thank you for helping me develop better skills to improve as a student! It is very apparent that you truly care about both physics and helping students learn and I wish more professors were like you! Once again, thank you so much and best of luck on all of your future endeavors!!!

This is not problem 13, 7th edition

By Mr. Dychko on Thu, 10/18/2018 - 13:02

Hi ragnarlaki, thanks for the comment. This is #13 in my copy of the 7th Edition. Are you using the "Global Edition", perhaps? Solutions for that are here: If not, I'd be curious as to what the ISBN is for your copy of the textbook.

Best wishes,
Mr. Dychko

For part c, how can you be certain to use 233.33 m/s as your velocity if this is the velocity give by the problem for the lowest point of the loop? I solved the problem by using 6.0g as my radial acceleration (i got the correct answer but I'm not sure why). Thank You.

Oops I misread the part where it said "same speed".

what about the 1/2's? don't they cancel?

By Mr. Dychko on Thu, 10/18/2018 - 13:04

Hi maizer01, thanks for the question. Are you referring to the 1/2 in front of each kinetic energy term in part b)? They don't cancel since 1/2 is not a common factor of all terms. There is a potential energy term which is not multiplied by 1/2, which means 1/2 is not a common factor.
All the best,
Mr. Dychko

On this problem, the equation for elastic collisions is vA - vB = v'A - v'B, but why is the one on #25 negative for the final velocity (v') side?

Wait! Nevermind - got it.

Hey, would you be able to put up the solution for question 13 of the chapter? It was a question on the number of electrons transferred after charge transfer.

There is a mistake in the video. Although the text is correct when talking about the permeability constant you say 4pi x 10^-4 as the text shows, the correct number is 4pi x 10^-7

By Mr. Dychko on Thu, 10/18/2018 - 13:10

Thank you very much ZreLL, I've added a note to the quick answer mentioning this error.
All the best,

Your welcome. Thank you for all the help with physics.

Giancoli 7th Edition, Chapter 6, Problem 38

By chaegyunkang on Sat, 09/22/2018 - 07:03

For part a, I made the kinetic energy zero thinking that the initial state would be when he was stationary on top of the platform (with only gravitational potential energy). Why is it wrong to use this as my initial state? I do understand how you made your initial state as the moment the person jumps off the platform.
