Momentum.

The formula for kinetic energy is: KE = .5 * m *v^2

The formula for momentum is: p = m * v

If an object has kinetic energy, then both mass and velocity are non-zero, which implies that the momentum is also non-zero.

An object that has linear momentum must also have acceleration angular momentum. This will also influence the kinetic and potential energy present.

Does linear motion have angular momentum?

I believe that any particle in linear motion must also have some angular momentum because all particles have spin. In the case of a photon the spin, wavelength and angular momentum all vary with the relative linear velocity. So in my point of view time itself is the ratio between relative linear and angular momentum.


How does mass affect angular momentum?

Short answer: Angular momentum is proportional to mass. If you double the mass of an object, you double its angular momentum.Long Answer:Angular Momentum is a characteristic of rotating bodies that is basically analogue to linear momentum for bodies moving in a straight line.It has a more complex definition. Relative to an origin, one obtains the position of the object, the vector r and the momentum of the object, the vector p, and then the angular momentum is the vector cross product, L.L=r X p.Since linear momentum, p=mv, is proportional to mass, so is angular momentum.Sometimes we speak of the angular momentum about the center of mass of an object, in which case one must add all of the bits of angular momentum for all the bits of mass at all the positions in the object. That is easiest using calculus.It should also be said that the moment of inertia, I, is proportional to mass and another way to express angular momentum is the moment of inertia times the angular velocity.


The momentum of an object depends on what two factors?

For an object to have momentum, it must have mass and velocity.


What must be exerted on an object to change the angular momentum?

A torque.


Does every transfer decrease momentum?

No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.

How does an object with higher momentum move?

Momentum is the product of velocity and mass - so to have a "higher momentum", the object must either be more massive, or it must move faster.


To have momentum an object must be?

Momentum = m v (mass, velocity). If either one is zero, momentum is zero. So in order to have momentum, an object must have both mass and speed, in the frame of reference.

What does the impulse-momentum theorem state?

Impulse equals change in momentum. "Apex" The final momentum of any object (or collection of objects) must equal to its initial momentum plus any impulse imparted to the object (or collection of objects).


Does every transfer decrease momentum?

No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.


What is momentum the measure of?

If an object is at rest it has inertia, which has to be overcome to make it move. When an object is moving in a straight line at a constant speed it has momentum, which must be overcome to slow or stop the object


What is one way to increase the momentum of an object?

Momentum is of two kind. One is linear momentum and the other is angular momentum. Linear momentum is defined as the product of the mass and the velocity. Hence a vector quantity. To change the momentum of a given body with its mass constant, its velocity is to be changed. Velocity change could be made by changing its magnitude or direction or both. Angular momentum is the product of moment of inertial and the angular velocity. Same manner, angular momentum is also a vector quantity as angular velocity is a vector quantity. Most of us think that moment of inertia of a body about any prescribed axis is also a vector quantity. It is totally wrong as far as my approach is concerned. Moment of inertia is a scalar quantity. So to change the momentum, some force can be applied by allowing a moving body to collide with. Angular momentum can be changed by applying torque on it. Torque colloquially saying is a turning force. Moment of effective force about an axis is termed as torque.


In order for a small object to have a large momentun the object needs to be stationary true or false?

False. The momentum of an object is given by the mass times the velocity of the object. Hence, a low-mass object must have a large velocity to have a large momentum.


What do you need to know to determine momentum?

To find the momentum of an object you must know the mass of the object and the velocity at which it travels. Example: A 50kg man runs at 10m/s. What is his momentum? Momentum = Mass x Velocity 50 x 10 = 500 kgm/s
