Jack and Jill go skydiving. Jack goes first. Jill jumps second. If Jill is higher up than Jack, who has more potential energy?
Jill
Thermal equilibrium is kinetic because the thermal energy moves _____ to _____ until both have reached the same _______. Tell me all 3
hot to cold
temperature
I fell down the stairs at my house. When did I(the system) have the most TOTAL amount of energy? (Potential + kinetic)
The whole time. It never changed.
The system has the most energy at every point because energy cannot be created nor destroyed, so the total energy remains constant.
