Question

select the statement that is not accurate about the following energy transformations. dante is using gravitational potential energy when walking to school. when dante is walking to school he is using mechanical energy. chemical energy is transferred to dante when he eats cereal. dante uses kinetic energy when he chews the cereal.

Explanation:

• Gravitational potential energy is related to height. When walking to school, Dante is not using gravitational potential energy in a significant way (unless there is a height change which is not indicated).
• Mechanical energy is the sum of kinetic and potential energy. When walking (which involves kinetic energy), mechanical energy is used.
• When eating cereal, chemical energy (stored in the food) is transferred to Dante.
• When chewing, there is motion (kinetic energy).

Answer:

Dante is using gravitational potential energy when walking to school.
