Eight Types Of Energy: Pullback Car
There are many forms of energy that are constantly changing into one form to another. Even though energy is always changing, energy cannot be created or destroyed. There are eight types of energy: potential, kinetic, mechanical, thermal, sound, light/radiation, nuclear, and electric energy. A pullback car uses and transforms many types of energy. It uses unbalanced forces to propel it forward and make it move. A pullback car uses kinetic energy and turns it into elastic potential energy when pulled back. When the car is released, the car accelerates and the elastic potential energy is transformed into kinetic energy. While the car is in motion, the friction from the ground rubbing against the wheels slow the car down. The kinetic energy is
transformed into potential energy and waste energy (thermal energy). This is an example of Newton’s third law which states, for every action there is an equal and opposite reaction. The pullback car will finally stop, according to Newton's first law of motion. This law states that an object will stay in motion until a force is acted upon it. Air resistance, friction, and gravity are all acting on the car, so the car will eventually stop. In conclusion, a pullback car uses and transforms many types of energy. It uses forms of energy to cause motion.
