Kaleb forgot to calculate his potential energy when he was walking briskly and running. How can he determine the missing measurements based on the data he has?
Kaleb would be able to determine the missing potential energies by doubling the kinetic energy. This would be correct because the potential energy is always double the kinetic energy when a person is in motion.
Kaleb would be able to determine the missing potential energies because if a person is moving they have kinetic energy, and a person cannot have kinetic and potential energy at the same time. The missing potential energies would be 0 J.
Kaleb would be able to determine the missing potential energies by subtracting the kinetic energy from the potential energy he measured when he was standing still. This would be correct because the potential energy is transformed to kinetic energy when he goes into motion.
Kaleb would be able to determine the missing potential energies by adding the 1,030 J to the kinetic energy when he was running and walking briskly. This would be correct because the potential energy is a constant, and the kinetic energy is added to it when he goes into motion.

Potential energy at Position “a” is the greatest, but kinetic energy changes as the height changes.
Potential energy at Position “c” is the greatest, but kinetic energy changes as the height changes.
Julius cooks some food on a grill. He claims that there are energy transformations occurring in the grill. His sister says he is wrong. What argument could Julius use to prove his sister wrong?
The propane gas used by the grill provides chemical energy. When the propane is burned in the grill for cooking, the chemical energy is converted to thermal and light energy. The thermal energy provides the heat for grilling food on the grill.
The propane gas used by the grill provides light energy from the flame that burns inside the grill. The light energy is converted into thermal energy that is used to cook the food on the grill.
The propane gas used by the grill contains thermal energy. The thermal energy is released as light energy when the flame is lit for the grill, and this energy is transformed into chemical energy when cooking the food on the grill.
The propane gas used by the grill supplies chemical energy when the propane is burned inside the grill. This energy is transformed into light energy when the flame is used to cook the food on the grill.
