At the most elementary level what causes particles to have momentum?

AI Thread Summary
Momentum is defined as the product of mass and velocity, represented by the equation p = mv, and it fundamentally relies on inertia. The underlying reason for mass having inertia remains unknown, prompting discussions about the Higgs particle, which is theorized to provide a mechanism for particles to acquire mass through interaction with a Higgs field. Some participants express skepticism about this explanation, noting that even prominent physicists like Hawking share doubts. The Large Hadron Collider (LHC) is expected to contribute to resolving these questions about mass and inertia. Overall, the nature of momentum and its relationship with mass and the Higgs particle continues to be a topic of significant inquiry in physics.

What is momentum? At the most elementary level what causes particles to have momentum? Also, does the higgs particle concern only a possible explanation for gravity or momentum as well?

\vec{p}=m\vec{v}
Just that.
 


Momentum is nothing without inertia.
Why does mass have inertia ? Nobody knows.
The Higgs particle is an attempt to find a mechanism for particles getting inertia. the suggestion is that there is an all-encompassing field (or two, or three...) whose quantum is the Higgs boson.
particles start with no inertia or mass, then they eat a few Higgs and get mass.
Don't think so.
I'm in good company, Hawking also doesn't think so.
The LHC may resolve this question.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
