Why pulling your arms in causes you to go faster?

When you are spinning there is a force called angular momentum that keeps you spinning and the angular momentum forms a ratio with the size of the object that is spinning so as you bring your arms inward, your size decreases increasing your angular momentum which spins you faster.


What keeps a spinner spinning?

It is conservation of [angular] momentum.


Conservation of angular momentum means that a spinning body tends to?

... to continue spinning.


What has angular momentum?

Anything that's spinning, rotating, tumbling, or traveling in a closed path around something else, has angular momentum.


What energy is spinning tops?

a spinning top has bothRotational kinetic energy and angular momentum in play as it spins...


How a yo-yo works?

A yo-yo has two kinds of kinetic energy, so it has two kinds of momentum and angular momentum. So anything that's spinning around likes to keep on spinning so its angular momentum stays the same.


What is the name of the mechanism that produces the amount of torque?

An angular force would produce a large torque like angular momentum of a spinning wheel.


What is the name of the mechanism that produces the greatest amount of torque?

An angular force would produce a large torque like angular momentum of a spinning wheel.


Why a bicycle cannot be balanced without moving?

The wheels of a bicycle will resist changes in their angular momentum when they are spinning, but will not when they are,


Do all objects have a momentum?

No. An object has momentum only if it is in motion..There are two kinds of momentum: linear momentum(or translational momentum), and angular momentum (or rotational momentum)..Linear momentum is a vector quantity and is calculated as mass x velocity (p = mv). Therefore, if an object's velocity is zero, then it has no linear momentum, but if an object is in motion, then it does have linear momentum..VERY IMPORTANT NOTE: Velocity, and therefore linear momentum, is always relative to the frame of reference. For a more complete discussion about velocity, see the related answer, referenced below, entitled 'How to Find Velocity'..Angular momentum is a pseudovector quantity that describes the momentum of an object that is spinning or rotating in place. An object has angular momentum only when it is spinning, or rotating about an axis. When an object is not spinning or rotating, then it does not have angular momentum..It is possible for an object to have only linear momentum, only angular momentum, or both angular and linear momentum. Note that this discussion falls apart in quantum mechanics, so we are only discussing classical physics - that is, every day observable objects, and not light particles (photons), electrons, or other quantum particles..All objects do have inertia, which is a resistance to a change in its momentum.


What is the difference between angular velocity and angular momentum?

angular momentum and angular velocity


What is gravitational force and angular momentum?

No one knows WHAT it is, but its the "force" that causes all matter to attract all other matter. Angular momentum is a measure of how much work it would take to make something stop spinning.
