    Inertia Mass
AI Thread Summary
Inertia is directly proportional to mass, meaning that an object with more mass has greater inertia. This implies that the larger the mass, the more it resists changes to its state of motion. While the effects of inertia are well understood, the fundamental reasons behind it remain unclear. Ongoing experiments at facilities like the LHC may provide further insights into this phenomenon. Overall, the initial assumption that more mass equates to more inertia is correct.

Which object has more inertia and why? The one that has more mass or less mass? I am asking this because I am not sure about this, but if I had to guess I'd say that the object with more mass has more inertia because its affected less by other objects than the object with less mass, well that's mine opinion so please correct me if I am wrong.

Inertia is proportional to mass.
 


So the bigger the mass the bigger inertia is? Does that mean that i am right?

If you were to say "more" mass, you would be correct.
 


However, be aware that inertia is a phenomenon that is NOT understood with respect to it's foundation.
That is: We fully understand it's effects, but not the cause.

Perhaps the experiments at LHC and other facilities can help.
 

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?
