WebMar 5, 2024 · There would be no harm done if you prefer to write Ek, Ep and E for kinetic, potential and total energy. I shall stick to T, U or V, and E. Now, instead of writing F = ma, we write, for each generalized coordinate, the Lagrangian equation (whose proof awaits a later chapter): [Math Processing Error] http://complex.gmu.edu/www-phys/phys705/notes/003%20Derivation%20of%20Lagrange%20equations%20from%20D%27Alembert.pdf

WebApr 11, 2024 · Such an equation will be useful because it can allow us to determine specific formulas for x(t). To derive the Euler-Lagrange equation, introduce some function η(t) that satisfies η(a) = η(b) = 0 and let ε be a real number variable that we can dial up and down. Then define the function X(t) as follows: X(t) = x(t) + ε η(t). how to watch echl
