What does the work-energy theorem state regarding the work done by a variable force?
A
The work done is equal to the change in kinetic energy of the system.
B
The work done is independent of the path taken by the system.
C
The work done is always zero for a closed system.
D
The work done can be calculated using only the initial and final velocities.
Correct Answer
Option A
Detailed Explanation
The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy, as expressed in K_f - K_i = W for variable forces.
