Question

What is the extended work-energy theorem including non-conservative forces?
Options
A W_nc = ΔKE
B W_nc = ΔPE
C W_nc = ΔKE + ΔPE = E_f - E_i
Correct Answer
D W_nc = 0
Correct Answer

Option C is the correct answer.

Detailed Explanation

When non-conservative forces are present, the work done by them equals the change in mechanical energy: W_nc = ΔKE + ΔPE = (KE_f + PE_f) - (KE_i + PE_i).

Hint

Non-conservative work changes the total mechanical energy.
