Consider a system consisting of the Earth, a vertical spring attached to the Earth, and a mass attached to the other end of the

Liula [17]

Answer:

The external force leads to an increase on gravitational and spring potential energies.

Explanation:

The system consists of a mass, resort and Earth. According to the Principle of Energy Conservation there is a potential energy as a consequence of the interaction between Earth and the mass and spring potential energy because of the spring deformation and, besides, the existence of work due to an external force:

$U_{g,A} + U_{k,A} + W_{ext} = U_{g,B} + U_{k,B}$

$W_{ext} = (U_{g,B}-U_{g,A}) + (U_{k,B}-U_{k,A})$

$F\cdot \Delta r = \frac{G\cdot m\cdot M}{r_{o}-\Delta r} - \frac{G\cdot m \cdot M}{r_{o}} +\frac{1}{2}\cdot k \cdot (x_{o}+\Delta r)^{2} - \frac{1}{2} \cdot k \cdot (x_{o})^{2}$

$F\cdot \Delta r = G\cdot m \cdot M \cdot \left(\frac{1}{r_{o}-\Delta r}-\frac{1}{r_{o}} \right)+\frac{1}{2}\cdot k \cdot [(x_{o}+\Delta r)^{2} -x_{o}^{2}]$

The external force leads to an increase on gravitational and spring potential energies.
