Several children are jumping up and down on a trampoline while their jumps are carefully observed by a physics student. Think of the trampoline, the children and the Earth as a defined system. Based on the data collected, the student suggests that the energy expended by the students does not match the macroscopic kinetic and potentia energies observed in the system at any one moment. Which of the following can best explain the energy discrepancy noted by the student? A. The student must have made an error in the calculation. B. Some of the expended energy has become thermal energy within parts of the system. C. The trampoline will add energy to the system due to having springs in its construction.. D. A system must have gained energy from an external source like a mechanical oscillator.
