A friction motor is a type of motor that operates by creating friction between two surfaces to generate movement. These motors are often found in toy cars and other small gadgets. To use a friction motor, one usually pulls the toy backward along a surface, which winds up a small internal gear or spring. When released, the stored energy is released, causing the toy to move forward. Friction motors are simple, mechanical devices that do not require batteries or electricity, making them both eco-friendly and fun for children to use in various play activities.
