A car traveled on a flat road. The car’s kinetic energy increased over time, while its potential energy remained constant. How did this change affect the car’s mechanical energy? 3 points
The car’s mechanical energy increased because the sum of the car’s kinetic and potential energy increased over time.
The car’s mechanical energy remained constant because the car’s potential energy remained constant.
The car’s mechanical energy decreased because the car’s kinetic energy increased.
There is no way to determine how the car’s mechanical energy changed based on the information presented.
