A force changes an object's kinetic energy from 65 J to 130 J. Calculate the work done by the force.

The work done ($W$) by a force is equal to the change in kinetic energy ($\Delta KE$).

$$W = \Delta KE = KE_{\text{final}} - KE_{\text{initial}}$$

Given:
Initial kinetic energy ($KE_{\text{initial}}$) = $65 \text{ J}$
Final kinetic energy ($KE_{\text{final}}$) = $130 \text{ J}$
