1: Lagrangian Mechanics UPDATED
ACTUAL Exam Questions and CORRECT
Answers
L = T-V - CORRECT ANSWER - Lagrangian
the action functional of the system derived from L must remain at a stationary point throughout
the time evolution of the system. Classical paths extremise the action, S. - CORRECT
ANSWER - The Principle of Least Action
S [q] ≡ tf_ti∫ L dt - CORRECT ANSWER - The action
(∂L/∂q) - d/dt (∂L/∂q̇' ) = 0 - CORRECT ANSWER - Euler Lagrange eqn.
the classical eqns of motion for Lagrangian mechanics - CORRECT ANSWER - Euler
Lagrange eqn. definition
A: action of variation
D: differentiate (keeping q and e constant)
S: simplify
I: integrate (by parts)
E: equation! - CORRECT ANSWER - deriving EL using explicit variation
