The second equation is the definition of angular momentum. To get from the first equation to the second equation, try writing out the vectors r and p in component form and taking the cross product. Then use the definitions of I and omega to show that both expressions are equivalent. In summary, to prove the given statement, write the vectors in component form, take the cross product, and use the definitions of I and omega to show the equivalence.

You mean get from the second equation to the first equation? The second equation is the definition of angular momentum.

Anyway, try writing out the vectors r and p in component form and taking the cross product. Then use the definitions of I and omega to show both expressions are the same.

Yes!
 

1. How do I approach proving a physics question?

The first step in proving a physics question is to understand the question and the concepts involved. Make sure you have a good grasp of the relevant equations and principles before attempting to solve the problem.

2. What are the key components of a physics proof?

A physics proof typically involves using mathematical equations and logical reasoning to demonstrate the validity of a hypothesis or theory. It may also involve experimentation and data analysis to support the proof.

3. What strategies can I use to prove a physics question?

One strategy is to break down the question into smaller, more manageable parts and work through them systematically. Another strategy is to use analogies or real-world examples to help understand and visualize the problem.

4. How do I know if my proof is correct?

You can check your proof by verifying that it follows the laws of physics and is consistent with known principles and equations. It can also be helpful to have someone else review your proof for any errors or oversights.

5. What should I do if I am struggling to prove a physics question?

If you are having difficulty proving a physics question, don't be afraid to seek help from a teacher, tutor, or fellow student. It can also be beneficial to review similar problems or practice with similar equations to strengthen your understanding and problem-solving skills.
