Question

Is the following statement correct about the total kinetic energy and total potential energy of non-conservative mechanical systems?

For non-conservative mechanical systems with external forces, the Lagrange dynamic function L can be defined as the sum of the total kinetic energy of the system and the total potential energy of the system.

Answer 1

For non-conservative mechanical systems with external forces, the Lagrangian dynamic function L can be defined as the difference between the total kinetic energy of the system and the total potential energy of the system, not the sum. Therefore, the statement is false.
