Working Principle

The DIY 3-Gear Speed Variable Car works on the principle of gear ratios and mechanical energy transfer. An electric motor, powered by batteries, generates rotational energy that drives the 3-speed gear system. The gears are designed to vary the car's speed and torque—smaller gears increase speed while reducing torque, and larger gears provide higher torque but lower speed. The rotational motion is transferred to the wheels through axles, propelling the car forward. A switch controls the motor, while the gear system allows manual adjustments to speed and torque. This hands-on project demonstrates the practical application of gear ratios and energy transfer, offering a fun and educational experience in mechanics and motion.
