How is momentum defined and is it different than velocity?

momentum is defined as p(momentum)=m(mass)*v(velocity). Thus, momentum is not the same as velocity becuase an object's momentum is dependent on its mass and velocity. Two objects traveling at the same speed but with extremely different masses will have very different momentums.

Calculatively, momentum is calculated as mass * velocity. It is very different than velocity in terms of units and in terms of concept.

mass*velocty=momentum(kg*m/s) like the other replies said, it's different from velocity but they're definitely related. if there's no velocity, there also can't be any momentum.

Momentum is the mass of a particle multiplied by its velocity. Momentum takes into account the mass of a particle in addition to its velocity.

Momentum is defined as p=mv (mass x velocity). The main difference between momentum and velocity is that momentum takes into account the mass of the object involved, where velocity does not.

Like previous answers mentioned, momentum is mass * velocity. So, if an object is moving at a slow velocity but has a large mass, it can still have a substantial momentum.

Momentum depends upon the variables mass and velocity (p=mv), while velocity is displacement and time.

The formula for momentum is p(momentum) = mass * velocity. Momentum is the quantity of motion that an object has, and it takes into account mass and velocity, while velocity is the rate of change of the position of an object.

Momentum also takes into account mass of an object, and defines how much force or energy it takes to move or stop an object. The heavier the object is, the more momentum it has.

momentum, p, is defined as mass (kg) multiplied by velocity (m/s): p=mv

velocity is used to define momentum

velocity is used to define momentum

Momentum refers to the quantity of motion an object has and is equal to mass times velocity.
