Tīmeklis2024. gada 8. aug. · The kinetic energy is. Therefore. and. On substituting these in Equation we obtain. This is one form of Lagrange’s equation of motion, and it often helps us to answer the question posed in the last sentence of Section 13.2 – namely to determine the generalized force associated with a given generalized coordinate. Tīmeklis2024. gada 8. aug. · Example 13.9. 1. Imagine that we have a particle than can move in one dimension (i.e. one coordinate – for example its height y above a table - suffices to describe its position), and that when its coordinate is y its potential energy is. (13.9.1) V = m g y. Its kinetic energy is, of course, (13.9.2) T = 1 2 m y ˙ 2.
