    Friction Vacuum
AI Thread Summary
In a frictionless environment, such as a maglev system, a vehicle must overcome its weight and the gravitational force acting on it when moving uphill. The key factor is the slope angle (A), which determines the additional force required to ascend. Specifically, the force needed to move uphill is equal to the weight of the object (W) multiplied by the sine of the slope angle (W.sin(A)). This discussion emphasizes the importance of understanding the forces at play in a vacuum-like scenario for effective vehicle design. The conversation seeks clarity on the physics involved in navigating elevation changes without friction.

Going uphill with no friction, think maglev, what forces would the mass/vehicle only have to overcome its weight... and gravity? I used the 'search' function but yielded no results.

Please feel free to discuss or to simply put me in the right direction.

Just to put things in context, I am trying to get a vehicle (similar to a maglev) down from a certain elevation and back up.

I apologize if it's an obvious question, shame on linguists for their lack of physics.

If the slope angle is A, and the maglev is exerting a force at right angles to the slope sufficient to prevent its landing, the additional force you need is one up the hill. If the weight of the object is W, the force you need to exceed is W.sin(A).
 

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...
