1. Types of energy used in this project are

kinetic energy- the energy of motion

potential energy- energy that is stored and held in readiness

Forms of kinetic and potential energy are:

mechanical energy- energy associated with motion or position of the object thermal energy- total energy of particles in an object chemical energy- energy stored in chemical compounds electric energy- energy that produces electricity electromagnetic energy- light energy that travels in waves nuclear energy- potential energy stored in the nucleus of an atom

2. Energy Uses for this Project:

We will use these energy forms for our project, but substitute nuclear energy with acoustic energy. Some examples that we can use for mechanical energy is dominoes, dropping a ball or marble, catapult. Also, we will use thermal energy. Some ways to use thermal energy will be creating a circuit with heat, using a toaster, or boiling water. Another energy transformation to use would be chemical energy. In our project, we could use a small bike, baking soda and vinegar, battery or even a baking soda and vinegar reaction. For electric energy we can use a circuit, a solar panel, an oven. For electromagnetic energy, we can use light by a light bulb, cell phone, iPod. Last but not least we will use acoustic energy which is the ball rolling down the slide, a marble hitting the car, and the two marbles hitting each other.

3. In the flashlight, I learned a lot about electrical energy, but also about other types of energy. I learned how to make a circuit, and I learned that a circuit doesn't work unless every part of the wire is attached to either a battery, bulb, or another wire. Even though we were mainly focusing on electrical energy in this experiment, many other types of energy came into play, like mechanical for moving the switch, chemical for using the batteries, electromagnetic from the light bulb, and thermal from the light bulb and the wires. The wires are connected to the light bulb, which gives off heat, or thermal energy. Our flashlight worked by having a light connected to a wire, which was connected to a battery, which was connected to a switch, which was connected to more wires and a battery. The energy flow starts in the switch, where t he switch converted mechanical energy, which is energy of motion, to electrical energy, which is energy carried through electrical currents. The battery converted chemical energy, which is energy stored in chemicals, to electrical energy. Once the electrons got to the light bulb, the bulb converted electrical energy to electromagnetic energy, or light energy, and thermal energy, or heat energy. By doing this, we learned how to make a circuit.

4. I learned a lot from the Energy Track experiment about friction, potential and kinetic energy, and conversions. I learned that with energy, no energy is stored- just transfered to different types of energy. The energy in the lab wasn't just for the marble moving, but also the acoustic energy and thermal energy which is friction. I learned that the marble had the most potential energy when Ms. Bercz was about to release it down the track and the marble had the most kinetic energy when the marble was about to stop. The energy kept on converting from mechanical to acoustic and thermal energy.
