7th Edition Solutions 6th Edition Solutions Global Edition Solutions

Features

  • 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!!!

As a Physics Instructor for the first time at a Community College, I found this resource incredibly helpful for my students and I highly recommend it to anyone using Giancoli's Textbook.

We are missing a squared sign for C in the equation

wait but isn't the arclength not the diameter itself though? wouldn't you have to set it to 2pi (because you found the arclength of the crater it would be 180 degrees) and then solve for r, and follow up with multiplying it by 2?

Giancoli 7th Edition, Chapter 3, Problem 24

By cmorales on Thu, 11/01/2018 - 14:22

I have some arguments from trigonometry students and their teacher reasoning that for #24 (chapter 3) the answer would be 0. I know this text states on page 63 that Sin2theta is 1 but their reasoning being supported by the calculator is convincing. Would you be able to give more insight to this question?
Thank you.

Hi cmorales, thank you for your question. The textbook question asks "What is the maximum horizontal range of your gun?". The gun is able to shoot, since we're given data about how long a shot straight up takes to return to the gun. This data is useful to determine the initial velocity that's possible for the gun. With that initial velocity in mind, we can calculate the maximum possible range, and it will certainly be more than zero. The angle at which the range is maximum is $45^\circ$, and taking the sine of two times that gives "one", which is the greatest possible sine value of any angle. Keep in mind that we're maximizing horizontal range, not vertical height... I'm just guessing at where the misunderstanding might be...

Oh I’m sorry, I didn’t realize I had the global edition

No worries, and thanks for letting me know that solved the problem!

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: https://www.giancolianswers.com/giancoli-physics-7th-global-edition-chap.... If not, I'd be curious as to what the ISBN is for your copy of the textbook.

Best wishes,

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
