Question

Plsss is urgent!!

7. A roller coaster cart falls from position A to position B. The cart then continues up the track to position C. A B Which sentence best describes the energy of the cart as it moves from position B to position C? A. The cart's gravitational potential energy transforms into kinetic energy. B. The cart's kinetic energy transforms into gravitational potential energy. C. The cart's total energy increases. D. The cart's total energy decreases. 8. Use the image from question #7. At which position is the kinetic energy the greatest? A. Position A B. Position B C. Position C D. Position D ​

Answer 1

7) The kinetic energy is transformed to gravitational potential energy. Option B

8) The kinetic energy is greatest at B.

Kinetic energy to gravitational potential energy in a roller coaster

A crucial component of a roller coaster's dynamics is the interaction between kinetic and gravitational potential energy. The roller coaster continuously shifts its energy between these two forms as it travels along its track.

The roller coaster has low kinetic energy and high potential energy when it is at the summit of a slope. Potential energy is transformed into kinetic energy as it falls, peaking at the foot of the hill.
