Difference between Classical Momentum and Relativistic Momentum

AI Thread Summary
In classical physics, momentum is defined as p=mv, where m is the rest mass. In relativistic physics, momentum is similarly defined, but m refers to the relativistic mass. The discussion highlights the confusion experienced by a college junior adjusting to a new physics curriculum, particularly regarding Lorentz Transformations. The student seeks clarification on whether these transformations affect velocity or are solely related to mass changes. Overall, the conversation emphasizes the transition from classical to relativistic concepts in physics.

Classical Physics states that:

p=mv

So, for special relativity, would momentum be defined in the same manner except m is now equal to the relativistic mass instead of the standard 'rest mass' as used in the classical equation?

Exactly,that's how momentum is defined for relatvistic systems...

What level of eduation do u have??

Daniel.
 
I am a junior in college. I just switched to a new university and my physics 3 professor is Russian and speaks 5% english... so I am feeling very uneasy about what we have learned so far. The Lorentz Transformations have thrown me through a loop. But as I find that more and more of my answers are correct that my confidence in this material is growing.

My main reason for asking this question was to ensure there wasnt any of the Transformations that had to apply to the velocity or anything of that nature. I was pretty sure it was just the mass change... but as I said... very iffy on the whole relativity thing at the moment. :biggrin:
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
