A pullback motor is a simple mechanical motor commonly used in toy cars and vehicles. It works by winding a small internal spring when the toy is pulled backward. Once released, the stored energy in the spring is released, causing the toy to move forward on its own. Pullback motors are powered by friction, meaning they do not require batteries or electricity. These motors are often found in small, colorful toy cars and are popular for their easy operation and fun, quick movement. They help children learn about motion and energy in a hands-on way.
