What Are Some Good Websites for Physics Practice Questions?

Click For Summary
For physics practice questions, several websites are recommended, including Khan Academy, which offers video tutorials and a variety of practice questions across numerous topics. Physics Forums serves as an online community where users can seek help from experts and access tutorials and study guides. The Physics Classroom, already noted for its tutorials, also provides interactive simulations, practice problems, and quizzes. These resources can effectively supplement learning and enhance understanding of physics concepts. Utilizing these sites can significantly aid in mastering physics topics.

Could someone please direct me to any good sites with tutorials for physics
i have been using the phytsics classroom one, which is excellent, but need something which is more practice questions now

Thanks guys :cry: :confused: :eek:
 
Physics news on Phys.org
Which topic do you wish to learn more about in particular? I think google would be a good choice first...
 


Hi there! I'm glad to hear that you have been finding the Physics Classroom tutorials helpful. It's always a good idea to supplement your learning with additional resources. Here are a few websites that I recommend for physics tutorials:

1. Khan Academy (https://www.khanacademy.org/science/physics): This is a great resource for both video tutorials and practice questions. They cover a wide range of topics and have a user-friendly interface.

2. Physics Forums (https://www.physicsforums.com/): This is an online community where you can ask questions and get help from experts and other students. They also have a section specifically for tutorials and study guides.

3. Physics Classroom (https://www.physicsclassroom.com/): This website offers more than just tutorials. They have interactive simulations, practice problems, and quizzes to help you solidify your understanding of physics concepts.

I hope these suggestions are helpful for your studies. Good luck with your physics journey! Don't hesitate to reach out if you have any other questions.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
