Choose the CORRECT statement(s) :

Options:(select one or more)

Answer:

C, D

Solution:

The work-energy theorem counts every force acting on the system - external and internal, conservative and non-conservative: their total work equals $Δ K E$ - (C) correct.

Since conservative work is $- Δ U$ , the same theorem reads $W_{e x t} + W_{n c} - Δ U = Δ K E$ - (D) correct. (A) and (B) leave out force classes.

Ans. (C,D)
