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.

p = mv
So one way to "increase" momentum of an object is to increase it's velocity relative to whatever you're (wisely) plotting to smash it in to.
Another method is to increase its mass, while keeping its relative velocity unchanged.
More interestingly, if you started playing with the Gravitational constant of the universe in spacially selective ways, you could probably increase momentum there to. Sadly, my Graviton distortion field device continues to cause plagues and floods in parts of the world and is thus not ready for this use. Sorry.

answer2:
Increase the momentum by a Force impulse, Fdt= dP.
(The effect of that is to increase the object's speed.)

∙ 12y agoMomentum is equal to an object's mass multiplied by its velocity. So, p=mv. In order to change the momentum of an object, then, either the mass must change or the object must accelerate (change in SPEED, not change in direction).

Why do you need momentum?
Momentum is defined as the "Mass in Motion". It is a Vector quantity. It depends on two variables (Object Mass and Velocity) . Its direction is same as objects velocity direction. In physics momentum is required to specify the motion of the object . If two bodies of same masses having different velocities have different momentum , in a similar way bodies of different masses having same velocity have different momentum. So , in order to describe the motion of object clearly one of the tool in classical mechanics is momentum
Which can be described as in an isolated system momentum is always conserved?
Briefly, the only way for an object to change its momentum is by transferring momentum to another object - in other words, the other object will receive a change in momentum in the opposite direction.
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.
Example of ways increasing friction?
Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
How do collision exemplify the law of conservation of momentum?
The vector sum of momenta before and after the collision is the same. One way to visualize this is that if one of the colliding objects changes its momentum (mass x velocity) in one direction, then the other colliding object must needs change its momentum in the opposite direction - by the same amount, except for the direction.
What are two ways you can increase the accelaration of an object?
There's only one way and that is to increase the force acting on it.

When you throw an object on another object it breaks the first one why?
Momentum and the fact that one object is sitting on something that prevents it from moving or 'bouncing' away from the force. It isn't always going to happen that way, though most of the time it would be true.

Does the speed at which an object passes by a planet effect the amount of gravity it experiences?
If the object has more speed, the effect of the planet's gravity is less significant, which is what I sense you wanted to know. The only factor affecting the amount of gravity experienced is the object's distance from the planet. The magnitude of the gravitational attraction between two masses is inversely proportional to the square of the distance between the masses, so if you double the distance, the attraction is one fourth of what it was. The trajectory of the passing object is determined by adding the vectors of the planet's gravity and the object's momentum. Momentum is the product of velocity, which is speed + direction, and mass. Therefore, if you increase either the speed or the mass, you increase the momentum, making it harder to change the object's speed or direction. It also means that a huge mass moving slowly can have the same momentum as a small object at a tremendous speed. It can be equally difficult to stop a slow freight train and a bullet.The closer the object's momentum is to zero, the more direct its acceleration toward the center of the planet is, and the closer the object's momentum is to infinity, the more it seems like the planet has no gravity at all by comparison.BTW, the way I remember when to use 'affect' and when to use 'effect' is by remembering that one's a verb and the other's a noun and that cause and effect are both nouns.
Define the momentum of a moving object?
Momentum is a quantity that describes both the mass and the velocity of an object. To find out the momentum of a given object, multiply the object's mass (kg) by its velocity (m/s).Think of it this way: momentum is sort of the "strength" of an object's motion. An object that has a lot of momentum will be harder to stop than an object that has less momentum.Which is harder to stop, a bowling ball or a golf ball? Well, if they are moving at the same velocity, the bowling ball will be tougher to stop, because it has more mass.How about if you have two 7 kg bowling balls that are both rolling toward you, but one is rolling at 0.5 m/s and the other is rolling at 10 m/s? You'd better get out of the way of the 10 m/s ball--it'll break your ankle! :-)This is why NFL linebackers are so large--it's tougher to stop a massive object in motion than a less massive object. :-)
When two object is move in opposite direction one will have positive and other have negative momentum why?
Momentum is defined as a vector quantity; this means that the direction matters. Only if it is defined as a vector quantity do you have something called "conservation of momentum", which makes it very interesting for physics.
