Is there maximal value for kinetic energy ?

AI Thread Summary
Kinetic energy does not have a maximum limit; it can increase indefinitely with velocity. The classical formula for kinetic energy, Ek = mv²/2, applies until speeds approach the speed of light. At relativistic speeds, the kinetic energy must be calculated using the formula Ek = mc²/√(1 - v²/c²) - mc². As a particle's velocity approaches the speed of light, its kinetic energy approaches infinity. Thus, there is no upper bound on kinetic energy in physics.

Is there a limit on value of kinetic energy ?
Ek= \frac{mv^2}{2} maximal mass ?

Something like plank length , plank temperature ...etc

Short answer: No

Long answer: Kinetic energy is unlimited. But if you use really high speed you need to use the relativistic version:

\frac{{mc^2 }}{{\sqrt {1 - \frac{{v^2 }}{{c^2 }}} }} - mc^2

As you can see, if a massive particle travels at v=c, kinetic energy becomes ∞.
 

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 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...

Thread 'Effect of mass on the acceleration of an elastic pendulum?'

I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?
