Which is true about the total energy at point S?
(1 point)
Responses
At point S, the total energy is three times the total energy of the system, as kinetic energy was increased.
At point S, the total energy is three times the total energy of the system, as kinetic energy was increased.
At point S, the total energy is double the total energy of the system, as new energy is created as the potential energy increases.
At point S, the total energy is double the total energy of the system, as new energy is created as the potential energy increases.
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.
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.
At point S, the total energy is half of the system’s total energy, as kinetic energy was destroyed.
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.
