What is friction on toy cars wheels?

Friction on toy car wheels is the resistance that occurs when the wheels roll over a surface. It is influenced by factors such as the material of the wheels, the surface texture, and the weight of the car. This friction allows the toy car to grip the surface and move forward, but too much friction can slow it down, while too little can cause it to skid. Ultimately, the right balance of friction is essential for optimal performance and control of the toy car.
