Does Eddy Current Braking on Roller Coasters Involve Constant Acceleration?

AI Thread Summary
Eddy current braking on roller coasters does not involve constant acceleration; instead, the braking force varies with speed. As the speed increases, the eddy currents generated are stronger, resulting in greater deceleration. This means that the deceleration is not uniform, leading to a variable rate of change in speed. The discussion also touches on the concept of "jerk," which refers to the rate of change of acceleration, suggesting that this too is not constant during the braking process. Overall, the braking mechanism is complex and depends on the speed of the coaster.

Hey, I am not from an english-speaking country, so excuse my art of writing english please:rolleyes:

My question is about the eddy current brake that is used by for example the roller coaster.
Does anyone know whether this brake procedure happens with constant acceleration?

For instance, when a free-fall tower breaks by using magnetic induction. Is there a constant acceleration or not?

nobody can help me?
 
Eddy current will be proportional to the time derivative if flux of magnetic induction. This time derivative of flux will be proportional to speed if a permanent magnet is used (or an electromagnet of constant field strength). The braking force will be proportional to Eddy current which will be higher at hiher speed. So deceleration will be stronger at higher speeds.
 
Does this mean that the time derivative of the deceleration is constant(I think this is called jerk?)
 
I think so, approximately.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
