the characteristics of the pull back car

The "shaft" connected to the rear tire of the pull-back car is fixedly connected to the gear in the pull-back gear. When the hand does work (drag) on ??the car backwards, the rear wheel rotates backward, and the force is transmitted through the shaft to the pull-back gear to do work, and the gear drives the pull-back gear. The structure (spring structure or rubber band structure) converts the kinetic energy of the hand into potential energy (for example, the rotation of the rubber band stretches or the spring compresses, etc.). When the hand is released, the car loses a force to maintain its balance, that is, the frictional force between the rear tire and the ground is increased when the car is pressed by hand (that is, the grip force commonly referred to in F1), and the pull-back gear becomes The reverse releases potential energy through the shaft to do work, so the shaft turns the potential energy into function. Since the pullback car is usually designed to drive the rear wheels forward (that is, the wheels are counterclockwise when viewed on the left side of the car), the pullback gear is designed to transfer energy backwards (that is, the wheels are clockwise when viewed from the left side of the car), and because usually the axles Therefore, as long as the pull-back gear can store a large amount (that is, the number of revolutions is enough) or the static friction with the ground is small enough, the pull-back car can move forward through the energy output of the heart of the pull-back gear.
