In physics, the momentum of an object is the amount of energy it has moving in a direction. It is a product of its mass (weight) and its velocity (speed and direction) as in (momentum = Mass times velocity). Momentum changes when speed is increased or decreased, its direction changes, or its mass changes.
An example of changing momentum is an object in space such as a meteor falling to the earth. Gravity can make it come down faster increasing its momentum. Atmospheric friction heats up the object causing some of it to burn away reducing its mass and decreasing its momentum.
Another example of momentum is a snowball rolling down a snow covered mountain. Gravity pulling it down increases it speed (velocity) and momentum. Rolling down in snow, it accumulates snow, gets larger, increasing in weight (mass) and momentum.

Momentum is the measure of?
velocity
What is the difference between a small momentum and a large momentum?
The larger the momentum, the harder it will be to stop it. Thus, the larger the force needed to decelarate the object. Since momentum is directly proportional to the velocity, the larger the momentum, the larger the velocity.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
What is momuntum?
Momentum: A measure of the motion of a body equal to the product of its mass and velocity.
How do the mass and velocity of a moving object affects its momentum?
As the velocity decreases, the momentum increases. Mass is the matter inside of something and momentum is how hard it is to stop something. Therefore momentum needs mass to function because without mass there would be no momentum. So think of the sentence above like this: velocity ( a measure of momentum) decreases, the momentum (including mass inside an object) goes up therefore making the mass increase while the velocity decreases.
What is the calculation of momentum?
Momentum of a particle is the measure of quantity of motion in its and is given by product of its mass and velocity. That is p = mv ,if m and v are known ,momentum can be calculated.
When a car increases its velocity its momentum?
When something increases in velocity, its momentum would increase because momentum is equal to its mass * velocity. This means that the momentum and velocity are proportional, so twice the velocity is twice the momentum, and so on.
What would be the momentum if the velocity were tripled?
Momentum is mass multiplied by velocity - so it is proportional to the velocity. If the velocity triples then so does the momentum
How velocity affect momentum?
if velocity increases, so does momentum. and vice versa momentum = mass x velocity increasing mass or velocity or both will increase momentum
How does velocity effect momentum?
if velocity increases, so does momentum. and vice versa momentum = mass x velocity increasing mass or velocity or both will increase momentum
Does momentum have a direction?
Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.
How do you determine mass using momentum and velocity?
Momentum = (mass) times (velocity)mass = (Momentum) divided by (velocity)
