False
Power is the measure of how quickly energy is transferred.
True
Atoms are made up of protons, neutrons, and electrons.

False
Study Notes
Energy Basics
- Power is the measure of how quickly energy is transferred.
- Energy is not the same as power, as energy is the ability to do work, while power is the rate of energy transfer.
Atomic Structure
- Atoms are composed of three main components: protons, neutrons, and electrons.
- Electrons orbit around the nucleus (center) of an atom, similar to how planets orbit around the sun.
Energy Types
- Chemical energy is not limited to fuels like coal, gasoline, natural gas, and sugar, but is a more general form of energy.
- Electrical energy comes from the movement of electrons, not protons, within an atom.
Energy Conversion
- When our bodies burn sugar during exercise, it is a conversion of chemical energy into other forms of energy.
