define momentum?

Answer 1

An objects momentum is the product of its mass and velocity:

p = m * v

It is a vector quantity, in that it has magnitude and direction.

Answer 2

The product of mass times the velocity of an object is called momentum.

Answer 3

In classical mechanics, momentum (pl. momenta; SI unit kg m/s) is the amount of mass moving, which can be written as the product of the mass and velocity of an object.

p = m*v

Momentum pertains to the quantity of motion that an object possesses. Any mass that is in motion has momentum. In fact, momentum depends upon mass and velocity, or in other words, the amount of "stuff" that is moving and how fast the "stuff" is moving. A train of roller coaster cars moving at a high speed has a lot of momentum. A tennis ball moving at a high speed has less momentum. And the building you are in, despite its large mass, has no momentum since it is at rest.

Answer 4

In classical mechanics, momentum (pl. momenta; SI unit kg m/s) is the amount of mass moving, which can be written as the product of the mass and velocity of an object. For more accurate measures of momentum, see the section "modern definitions of momentum" on this page.

In general the momentum of an object can be conceptually thought of as the tendency of an object to continue to move in its direction of travel, unless acted on by a net external force. As such, it is a natural consequence of Newton's first and second laws of motion.

Momentum is a conserved quantity, meaning that the total momentum of any closed system (one not affected by external forces, and whose internal forces are not dissipative in nature) cannot be changed.

The concept of momentum in classical mechanics was originated by a number of great thinkers and experimentalists. René Descartes referred to mass times velocity as the fundamental force of motion. Galileo Galilei in his Two New Sciences used the term "impeto" (Italian), while Newton's Laws of Motion uses motus (Latin), which has has been interpreted by subsequent scholars to mean momentum.

If an object is moving in any reference frame, then it has momentum in that frame. It is important to note that momentum is frame dependent. That is, the same object may have a certain momentum in one frame of reference, but a different amount in another frame.

The amount of momentum that an object has depends on two physical quantities: the mass and the velocity of the moving object in the frame of reference. In physics, the symbol for momentum is usually denoted by a small p (bolded because it is a vector), so this can be written:

p=mv
where:

p is the momentum
m is the mass
v the velocity

Answer 5

Force exerted on an object over time equals momentum. That is,

F * dt = p

where F is force, dt is time interval, and p is momentum. Energy is defined as:

F * dx = E

where F is force, dx is position interval or distance, and E is energy.

These terms are general and apply not only to Newtonian physics, but quantum and relativistic as well. The problem with this definition of momentum:

m v = p

is that it's only true for Newtonian physics, but not anywhere else.

Given that F * dt = p and F * dx = E, we have

dF * dt = dp
dF * dx = dE

dividing the 2nd by the 1st, we have:

dx/dt = v = dE/dp

Again, an important relation that's true in Newtonian, Relativistic, and Quantum physics.

Answer 6

Momentum is the product of the mass of an object with its velocity.

Answer 7

momentum=massxvelocity

momentum is defined as the product of the mass and the velocity of a body.

Answer 8

An objects momentum is the product of its mass and velocity:

p = m * v
