2. Electric Racing Car
3. Hand-Cranked Generator
The Paddle Wheel Boat demonstrates the principle of propulsion using paddle wheels. The rotation of the paddle wheels pushes water backward, and the reaction force propels the boat forward.
The Electric Racing Car features a chassis with a battery box connected to a motor. It uses gears and wheels to convert electrical energy into motion.
The Hand-Cranked Generator allows manual generation of electricity through a hand crank mechanism.
