AI Thread Summary

The discussion centers on the equation for kinetic energy, specifically questioning the derivation of mv^2 and the absence of the 1/2 factor. The participant initially calculated kinetic energy as (1/2)mv^2 but is confused about how the simplified form mv^2 is achieved. Clarification is provided that the mv^2 term results from combining two instances of (1/2)mv^2. The conversation references the rotational kinetic energy formula to illustrate the point. Understanding the context of combining terms is essential for grasping the equation's derivation.

Homework Statement

How did they get mv^2? Where did the 1/2 go? I tried working out the equation below the question and I ended up getting (1/2)mv^2.
Look at the image to see. It's the rotational kinetic energy formula.

Their mv² came from combining ½mv² + ½mv²

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:
