Momentum

AI Thread Summary

In collisions involving rolling objects, both linear and angular momentum must be considered to accurately describe the system. The conservation of momentum equation, m1u1 + m2u2 = m1v1 + m2v2, can be expanded to include angular momentum by incorporating the moment of inertia and angular velocity. This integration allows for a comprehensive analysis of scenarios where an object rolls, such as a ball influenced by water flow. It is essential to combine linear and angular momentum equations rather than treating them independently for a complete understanding of the dynamics involved. Overall, the conservation principles apply to both types of momentum in these complex interactions.

If 2 molecules collide, m1u1+m2u2 = m1v1+m2v2. However let's say the object hit rolls. How would that factor be dealt with in terms of momentum

By including the angular momentum: moment of inertia times angular velocity.

can you combine an equation with linear and angular momentum or do you have to do it independently? e.g in the case of a flow of water causing a ball to roll

Thread 'Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?'

Here is what I tried This question was actually asked in one of our engineering entrances. The answer was 1D. My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
