Angular Momentum

The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…

Moment of a Force

The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…

Textbook Question

Chapter 11, Problem 58PCE

A student on a piano stool rotates freely with an angular speed of 2 95 rev/s The student holds a 1.25-kg mass in each outstretched arm 0.759 m from the axis of rotation The combined moment of inertia of the student and the stool, ignoring the two masses is 5.43 kg · m². a value that remains constant (a) As the student pulls his arms inward, his angular speed increases to 3.54 rev/s How far are the masses from the axis of rotation at this time considering the masses to be points? (b) Calculate the initial and final kinetic energies of the system

Helicobacter pylori (H. pylori) is a helically-shaped bacterium that is usually found in the stomach. It burrows through the gastric mucous lining to establish an infection in the stomach's epithelial cells (see photo). Approximately 90% of the people infected with H. pylori will never experience symptoms. Others may develop peptic ulcers and show symptoms of chronic gastritis. The method of motility of H. pylori is a prokaryotic flagellum attached to the back of the bacterium that rigidly rotates like a propeller on a ship. The flagellum is composed of proteins and is approximately 40.0 nm in diameter and can reach rotation speeds as high as 1.50 x 103 rpm. If the speed of the bacterium is 10.0 μm/s, how far has it moved in the time it takes the flagellum to rotate through an angular displacement of 5.00 * 10² rad?
