Answer each question in order 1-11 and I want you to answer in a very short sentence. answer like o=you are in 8th grade student

Answer 1

1. Energy is defined as the ability to do work or cause change.

2. Three forms of energy are:
- Kinetic energy (e.g., a moving car),
- Potential energy (e.g., a stretched rubber band),
- Thermal energy (e.g., heat from a stove).

3. Chemical energy is the energy stored in the bonds of chemical compounds, like in food or gasoline.

4. Sound energy is produced by vibrations and can be heard, while light energy is visible electromagnetic radiation.

5. Electrical energy is the energy produced by moving electric charges.

6. Nuclear energy is the energy released during nuclear reactions, like in the sun or nuclear power plants.

7. The law of conservation of energy states that energy cannot be created or destroyed, only transformed.

8. Energy is transformed when it changes from one form to another, like when a light bulb converts electrical energy to light energy.

9. Some examples of energy transformations are:
- A toaster converting electrical energy to thermal energy.
- A windmill converting kinetic energy of wind to electrical energy.

10. Some sources of energy include fossil fuels, solar energy, wind energy, and hydroelectric power.

11. Energy is measured in joules (J), calories, or kilowatt-hours (kWh).
