Xiao Ming takes a bus every day when he goes to school. He finds that when the car starts, the engine works with a loud roar. The speed of the car increases from static to moving, while the car keeps moving at a constant speed between two stations. Xiao Ming finds that the engine is still working. When the car comes in, the driver turns off the engine in time, and the speed of the car slows down, Until stop at the platform. If the road is flat, please analyze the main energy conversion and transfer of the car in the three stages of start, on the way and in the station. It is probably the energy conversion from the car start to the brake stop

1: Starting acceleration: the engine of a car converts the heat energy of the fuel (gasoline or diesel, or natural gas) into the kinetic energy of the driving vehicle, and at the same time, it also overcomes the rolling resistance of the wheels and the air resistance

Is the resultant force of a car with traction equal to the difference or sum of the traction and resistance?
Why? Is the traction force the resultant force on the object? The traction force does not change,

Traction force --- 1. That is, pulling force, pulling force. It refers to the force exerted on an object by means of pulling along a certain direction. 2. In engineering, it refers to the bearing capacity generated by machinery, usually expressed in power. 3. It generally refers to the force that produces pulling action or equivalent pulling action
