Scalar Vector

AI Thread Summary

The discussion revolves around the operations involving dot and cross products in vector mathematics. It clarifies that a dot product results in a scalar, while a cross product yields a vector. The addition and subtraction of vectors maintain the vector nature of the result. Participants emphasize understanding how these operations interact, particularly in mixed expressions. The thread seeks guidance on determining the outcomes of specific vector operations.

Addition and subtraction of anything always results in the same thing.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
