Scenario Consider a car that is initially moving on a straight roadway. The road may be an uphill road, a downhill road, or a flat road. The driver of the car may be pressing the gas pedal, the brake pedal, or neither pedal. The only energy transformations that can take place are chemical energy becoming mechanical energy when the gas pedal is pressed) and mechanical energy becoming thermal energy (when the brake pedal is pressed). (Chemical energy levels may be thought about as the level of the gas gauge.) Data Analysis For each situation, fill in the sentence explaining how each system's mechanical energy is changing, create an energy bar chart representing the energy transformation, and use the blank space to explain how you formulated your answers.
