An air track is used as a model for momentum because the air hovering beneath the track minimizes friction, allowing objects to move with almost no resistance. This setup allows for more accurate measurements of the conservation of momentum in collisions and interactions between objects.
What else can I help you with?
Which is not a force weight air friction resistance momentum?
Momentum is not a force. Momentum is a property of a moving object that depends on its mass and velocity. Forces, such as weight, air resistance, and resistance, act upon objects to change their momentum.
In the verification of conservation of momentumwhy is it better to make use of an air track rather than a trolley system?
An air track provides a nearly frictionless surface for objects to move on, allowing for more accurate measurements of momentum conservation. This eliminates the need to account for frictional forces when analyzing the motion of objects, making it a better choice for verifying conservation of momentum compared to a trolley system which would have more sources of friction.
What is the name of the model used to describe air circulation?
The model commonly used to describe air circulation is the Hadley cell model. This model explains the global pattern of atmospheric circulation, including the movement of warm air towards the poles and cool air towards the equator.
Under what circumstances is momentum not conserved?
Momentum is not conserved when external forces act on a system, such as friction or air resistance, causing a change in the total momentum of the system.
How air friction affect momentum?
Air friction acts as a force that opposes the motion of an object, causing a decrease in its velocity. This decrease in velocity results in a decrease in the object's momentum over time. Essentially, air friction reduces the momentum of an object by transferring some of the object's kinetic energy into heat energy as it moves through the air.
What are the uses of a linear air track?
A linear air track is typically used in the study of motion in physics. Depending of the different tracks available, different experiments can be conducted. These range from proving the conservation of momentum (m1*u1 + m2*u2 = m1*v1 + m2*v2), to finding the rate of acceleration (a = difference in velocity/difference in time).

What are the physics principles in working of a roler coaster?
Firstly, gravity. Roller coasters work by dragging the train to the top of the track, then letting it roll down using the acceleration of gravity. Momentum takes it back up to the top of the next bump, having to overcome rolling friction all the way through the track. Upset stomachs are caused by the inertia and momentum of your insides. Every bit of the track involves momentum, velocity, acceleration, air resistance, etc... Stopping at the end is just an application of friction through the breaks.
What effect does running around a track have on momentum?
During Track and Field meet, momentum can be observed almost everywhere. Especially in the field events (jumping events and throwing events) where maximizing momentum is the key to performing well. In throwing events such as javelin, shot put, hammer and discus, competitors get to apply force to the object for a brief moment of time. After that, forces acting on the objects are all against the forward motion (i.e. gravitational force, air friction…). At this point momentum is all that is left to keep it going forward.

How are hot air balloons used to track weather?
they can follow clouds or storms.

Why running starts are importantin some sport?
well for example with the high jump in track a running start gets your momentum going so it is a little bit easier to get your body up in the air and over the bar.
What forces act against momentum?
I don't see how anything can "act against momentum"; momentum is always conserved. If there is friction, the movement of the object will be slowed down; but in this case, momentum is transferred to the air, or whatever is slowing down the object in question. Total momentum will be conserved.
