Hello. I've searched the internet hard but couldn't find anything about this so i decided to ask this to physicsforums. If a car is up a slope with friction and it's stopping(balanced) by using the gas pedal, what is the energy consumed by the motor of the car? I know F.x is 0 in this situation but if i'm using the gas pedal, energy must be consumed right? I'm starving for the answer, thank you for your interests!
