Calculating Angular Momentum: Axis of Rotation Explained

Click For Summary
Angular momentum is calculated based on the axis of rotation, which is crucial for determining both moment of inertia and angular velocity. The equation for angular momentum, expressed as L = Iω, highlights the dependence on the chosen axis. The moment of inertia varies with the axis, affecting the overall angular momentum. The infographic in the linked Wikipedia article illustrates how angular momentum is represented as a vector in three dimensions, emphasizing the importance of the rotation axis. Understanding these relationships is essential for accurate calculations in physics.

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
