Answer #1:
An Example of momentum is when a Big truck rolls down a hill, and then a little
car rolls down a hill. The Truck goes faster because it had a larger mass which
gave it more momentum.
===============================
Answer #2:
The answer above illustrates a classic misunderstanding of gravity ... one that
was debunked roughly 500 years ago, but is apparently so appealing to human
senses that it refuses to die. The simple fact is that if nothing interferes with
them, then the smallest lightest objects and the biggest heaviest objects all
fall at the same rate.
Neglecting the change in the position of the earth, the truck slides down the
hill at the same speed as the car, or any other frictionless object. The size of
the trucks wheels does matter slightly, as larger wheels possess much more
angular momentum, which is sort of like a measure of how much additional
inertia an object has due to its resistance to rotation. Another error illustrated
above is the belief that mass and momentum are the same thing. While
momentum is proportional to mass, other factors are involved as well.
Momentum in Classical physics is given as follows: momentum = mass * velocity. This is inaccurate, however, if we wish to use momentum to model energy
transfers in collisions (which is mostly what it is used for). A more accurate
formula would be something like:
momentum =
{ (rest mass + extra mass due to motion) * velocity } + momentum due to wave properties.
where the momentum due to wave properties is given by:
plank's constant/wavelength for light and some other mediumless waves.
An example illustrating the usefulness of momentum as a concept in physics is
the idea of a solar sail, whereby a spacecraft could propel itself by reflecting
light off of giant mirrored sheets, sailing on a solar wind. This is only possible
because light has momentum and a portion of that momentum would be
transferred to the ship as the light bounced off/was reflected by/was absorbed
by the sail.

What is an example of low momentum?
Momentum = Mass x Velocity (p=mv)Of course an object at rest would have no momentum no matter what the mass is (velocity = 0 so momentum = 0).Playing volleyball with a balloon might be something that would be considered low momentum. You can hit it as hard as you like, but it has so little mass that its momentum can hardly overcome the air resistance.You might push a small car at, say 1/4 MPH, and it would have relatively little momentum.However a train traveling at the same 1/4 MPH would still have a lot of momentum.
State and explain the law of conservation of momentum?
The law of conservation of momentum is Newton's 3rd law' The vectors sum to zero: 0 = F1 + F2 = dp1/dt + dp2/dt = d(p1 + p2)/dt =0. Thus, p1 + p2 = a constant, thus, the conservation of momentum.
Does the p in p mv mean position?
No it does not. It represents momentum.
Momentum of a system is conserved only when?
When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.
When objects collide the totol inital momentum equals the total final momentum is what?
law of conservation of momentum
What is one example of conserved momentum?
One example of conserved momentum is a collision between two objects where the total momentum before the collision is equal to the total momentum after the collision. This is known as conservation of momentum.
An example of momentum?
Momentum is motion. When a car is moving it is exhibiting momentum. A young professional getting promotions is experiencing momentum.
What is an example of an object with a momentum of zero?
An object at rest has zero momentum. For example, a stationary rock on the ground has zero momentum because both its mass and velocity are zero.
What is a example of a momentum of zero?
An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.
What is and example of conservation of momentum?
In an isolated system the total momentum of a system remains conserved. For example If you fire a bullet from Gun , bullet go forward with some linear momentum and in order to conserve the linear momentum the gun recoils
Is an example of conservation of momentum?
Elastic collision.
What is an example of an event when momentum is not conserved?
An example of an event when momentum is not conserved is when two ice skaters on frictionless ice push off each other. When they push off, one gains momentum in the opposite direction, causing the total momentum of the system to change from the initial state. This violates the principle of conservation of momentum.
What is the best example of transfer of momentum?
In an isolated system the total momentum of a system remains conserved. For example If you fire a bullet from Gun , bullet go forward with some linear momentum and in order to conserve the linear momentum the gun recoils
What is an example of a momentum problem?
An example of a momentum problem could involve calculating the momentum of a moving object by multiplying its mass by its velocity. For instance, if a car with a mass of 1000 kg is travelling at a velocity of 20 m/s, its momentum would be 20,000 kg*m/s.
What is example of visible momentum?
An example of visible momentum is a moving car accelerating on a highway. As the car gains speed and covers more distance in a short amount of time, you can visually see the momentum it possesses. The increase in speed and movement of the car are clear indicators of its visible momentum.
Billiard balls colliding is an example?
An example of the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant before and after a collision.
Give two examples showing the conservation of momentum give one example where momentum is not conserved?
Momentum like mass will always be conserved in any process. Momentum is the product of mass and velocity of the object. It is symbolically denoted as p=m*v where p = momentum, m = mass and v = velocity
