6. 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? *

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
