The energy stored in the train at 2 is transformed from BLANK energy into motion, thermal, and sound energy as the train moves down to 3, As the train comes back up to 4, BLANK the energy is transformed back into BLANK energy, but some BLANK energy remains because 4 is not as high as 2.

Question

The blanks are either kinetic or potential

Answer 1

The energy stored in the train at 2 is transformed from potential energy into motion, thermal, and sound energy as the train moves down to 3. As the train comes back up to 4, some of the energy is transformed back into potential energy, but some kinetic energy remains because 4 is not as high as 2.
