Gravity Car Course Presentation
The feature of a gravity car is to change periodically.center of gravityTo achieve a vehicle that relies on its own gravity to drive, the technical challenge is how to make the force that changes the center of gravity smaller, and how to move a greater distance under the same force.
Experimental Purpose: 1. Use the principle of a heavy object falling to drive a wheel to build a car.
2. Introduce students to the law of conservation of energy briefly.
Experiment Report:
When a heavy object falls and pulls the wheel to rotate, what is at the top of the rack? It is called a fixed pulley. What is its function? It can change the direction of the force. Imagine, the heavy object is affected by gravity and moves downward, producing downward kinetic energy. By using the rope and the fixed pulley, the direction of the force is changed to make the other end move upward. The rope pulls the rope wrapped around the shaft to make the wheel rotate, achieving the purpose of movement.
So, what makes the car go faster and farther?
