    Inertia Origin
AI Thread Summary
Inertia is not a force but rather a property of matter that describes its resistance to changes in motion. When an observer feels a force during acceleration, it is due to the application of an external force, such as electromagnetic interactions between particles. Acceleration involves changes in velocity, which can occur through variations in speed or direction, leading to the sensation of force. The underlying cause of mass, which relates to inertia, is still not fully understood, with theories suggesting the Higgs particle's interaction with the Higgs field as a potential explanation. Ultimately, the discussion highlights the complexities surrounding the concepts of inertia and mass in physics.

Hi, so i have a fairly good understanding of most of the concepts relating to inertia. but my question is what is the force felt by the observer while accelerating. for example the force gravity can be described as space bending into shapes around the body of mass, the other can be described as the exchange of quantum particles and other such as centripetal force as simply felt because we want to be traveling in a straight. so once again what is the causes the force of inertia.

And what exactly have you understood here?

There is no "force of inertia". If you are sitting in a car that accelerates from 0 to 60 mph, I presume that you will want to accelerate with it! And that requires that a force be applied to you. If you are really concerned about "quantum particles" then it is a matter of electro-magnetic forces. The electrons in the seat push against the electrons in your body.

Acceleration is defined as a change in velocity. Velocity has components speed and direction. If you change either the speed or the direction then you change your velocity and that means you are accelerating. So the force you feel when rotating is also a "force felt by the observer while accelerating".
 
Perhaps what you are really asking is "What gives objects mass"?

The short answer is we don't know. One theory is that it's caused by the Higgs particle interacting with the Higgs field.

or perhaps you wan to know the source of inertia...

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?
