WebJul 10, 2024 · You're never going to derive the curvature in a Newtonian derivation, since it happens in flat space. The best you can do is to note that you have some constant; you have to compare with the actual relativistic equation to identify it as the curvature.

Curvature and Radius of Curvature Differential Calculus

WebCurvature is computed by first finding a unit tangent vector function, then finding its derivative with respect to arc length. Here we start thinking about what that means. … WebCurvature is about the speed by which this tangent vector turns. As this is a purely geometric concept time t should not enter into the definition. This means that we have to measure this speed with respect to arc length s. The polar angle of the tangent vector is given by θ ( t) = arg ( z ˙ ( t)).

And the derivative of the y component of one minus cosine t, y prime of t, is gonna be, derivative of cosine is negative sine so negative derivative of that is sine, and that one goes to a constant, and ... WebThe curvature, inertia, and polarisation drifts result from treating the acceleration of the particle as fictitious forces. The diamagnetic drift can be derived from the force due to a pressure gradient. Finally, other forces such as radiation pressure and collisions also result in drifts.

"WebCurvature (symbol, $\kappa$) is the mathematical expression of how much a curve actually curved. It is the measure of the average change in direction of the curve per unit of arc. Imagine a particle to move along the circle from point 1 to point 2, the higher the number of $\kappa$, the more quickly the particle changes in direction. This quick change in … " - Curvature derivation
