Question

Energy conversion from potential energy (the energy of position or composition) to kinetic energy (the energy of motion) is illustrated by the diagram of a roller coaster. When the coaster is in position A, the potential energy is and the kinetic energy is . As the coaster moves to position B, the potential energy is and the kinetic energy is . As momentum carries the coaster into position C, the potential energy is and the kinetic energy is . Finally as the coaster reaches position D, the potential energy is and the kinetic energy is

Answer 1

The following is an elaboration of the differences in potential and kinetic energies based on the diagram of the roller coaster:

• When the coaster is in position A, the potential energy is maximum and the kinetic energy is minimum.
• As the coaster moves to position B, the potential energy is minimum and the kinetic energy is maximum .
• As momentum carries the coaster into position C, the potential energy is minimum and the kinetic energy is maximum.
• Finally, as the coaster reaches position D, the potential energy is maximum and the kinetic energy is minimum.

Answer 2

Answer:

1 - Highest value

2 - Lowest value

3 - Decreased to half the original value

4 - Increased to Half its maximum value

5 - Increased 3/4 of the original value

6 - Decreased to 1/4 of its maximum value

7 - At it's lowest value

8 - At it's maximum value
