In this activity, students will play with cars to discover how potential and kinetic energy make them move.
With competitive price and timely delivery, Habibi sincerely hope to be your supplier and partner.
Toy cars use a variety of mechanisms to make them go, but they all store up potential energy.
For more information, please visit Children Ride On Toy Car.
Although the elastic material inside is usually steel and not rubber, the principle is the same. By changing the shape of the material (usually a coil of metal) energy is stored and then released as motion.

The Pull-Back Toy Car is an incredible piece of engineering! This is sometimes called a "Wind-Up" toy car. This videos covers the specifics of the mechanism: the motor chassis, the 5 gears, and the torsion spring. We'll talk briefly about gear ratios, gear trains, and also cover why you hear that mysterious clicking noise when it winds up enough.
