Which is true about the total energy at point S?
(1 point)
Responses
A.At point S, the total energy is double the total energy of the system, as new energy is created as the potential energy increases.
B.At point S, the total energy is half of the system’s total energy, as kinetic energy was destroyed.
C.At point S, the total energy is equal to the total energy of the system because energy kinetic energy has been transformed to potential energy.
D.At point S, the total energy is three times the total energy of the system, as kinetic energy was increased.
1 answer
The correct response is:
C. At point S, the total energy is equal to the total energy of the system because kinetic energy has been transformed to potential energy.
In a closed system, the total mechanical energy (potential energy + kinetic energy) remains constant throughout the motion, assuming no external forces (like air resistance) are doing work on the system. As the baseball rises, kinetic energy is converted into potential energy, but the total energy of the system remains the same.
