A: ### Quick Answer

**As explained by Hyperphysics, angular momentum is calculated by finding the product of the moment of inertia and the angular velocity of a rotating body or system.** The moment of inertia with respect to an axis is the product of the mass times the distance from the axis squared, and angular velocity is the rate of change of angular displacement.

Einstein Online defines angular momentum, for an object orbiting a central point, as the product of the object’s mass times its distance from the axis times the velocity at which it orbits around the center. Angular momentum is understood as the momentum of rotation, or an object’s resistance to change in rotation. Angular momentum is a vector quantity requiring both magnitude and direction. The direction of the angular momentum vector is the same as the axis of rotation of the object using the right-hand rule, explains Real World Physics.

Encyclopædia Britannica states that the total angular momentum for a given object or system isolated from external forces is a constant, which is known as the law of conservation of angular momentum. The units for angular momentum are kilogram meters squared per second (kg ? m2 / sec). A child’s yo-yo builds angular momentum as the string unwinds and the spool spins, causing the yo-yo to continue spinning after reaching the end of the string, states HowStuffWorks.

## How do you calculate the max height equation?

A:The maximum height of a projectile is calculated with the equation h = vy^2/2g, where g is the gravitational acceleration on Earth, 9.81 meters per second, h is the maximum height and vy is the vertical component of the projectile's velocity. If the angle of launch or the velocity of the projectile are not known, these quantities can be derived.

## How do I calculate shear stress?

A:

Full Answer >**Shear stress is calculated by dividing the force exerted on an object by that object's cross-sectional area.**Shear stress is one of the three primary stresses present in nature, which also includes tension and compression. This form of stress is the result of forces applied parallel to a surface. Typically, the symbol for a given stress is the Greek symbol "tau," or "τ."Filed Under: - Q:
## How do you calculate muzzle velocity?

A:

Full Answer >**According to Pyramid Air Gun Mall, muzzle velocity is calculated by multiplying the grain of the bullet or pellet being fired from the gun by the feet per second the bullet travels after being fired.**Divide this number by 450,240 to calculate muzzle velocity. The final number is a constant derived by two times the acceleration of gravity by 7,000, which is the number of grains in a pound.Filed Under: - Q:
## What is the moment of inertia of a cylinder?

A:The moment of inertia of a solid cylinder is equal to one half of the mass multiplied by the square of the radius. This equation should be used to find the cylinder's moment of inertia with respect to the z-axis, or the plane parallel to the cylinder's height.
