- Agravitational potential energy $\rightarrow$ internal energy $\rightarrow$ kinetic energy
- Bgravitational potential energy $\rightarrow$ kinetic energy $\rightarrow$ internal energy
- Ckinetic energy $\rightarrow$ gravitational potential energy $\rightarrow$ internal energy
- Dkinetic energy $\rightarrow$ internal energy $\rightarrow$ gravitational potential energy
