Question | Answer |
Energy | the ability to make things move; has no mass and takes up no space |
Matter | has mass and takes up space |
Chemical Energy | holds the atoms in molecules together; stored in all living things |
Electrical Energy | electricity; electrons flowing through matter |
Thermal Energy | heat |
Electromagnetic Energy | light |
Mechanical Energy | energy of moving objects |
Nuclear Energy | holds protons and neutrons together in the nucleus of atoms |
Sound Energy | vibrates air molecules and bones in your ear |
Kinetic Energy | energy in action |
Potential Energy | stored energy because of position or chemistry |
Conversion | energy changes from one form to another; transformation |
Law of Conservation of Energy | Energy cannot be made. Energy cannot be destroyed. Energy can change from one form to another. |
Photosynthesis | the process by which plants change the light from the sun into chemical energy |
Fossil Fuels | substanaces like coal, oil, and natural gas which store chemical energy from the remains of ancient plants and animals |
Forms of Potential Energy | nuclear and chemical |
forms of kinetic energy | thermal, electromagnetic, electrical, mechanical, sound |
position | a way of having potential energy based on the location of the object such as on a high shelf or the top of a hill |
chemistry | a way of having potential energy based on the what the object is made of and its ability to give off energy |
chemical to heat | conversion that occurs in your body |
mechanical to sound | conversion that occurs in most instruments |
chemical to mechanical | conversion that occurs in automobiles like cars and planes |
electrical to light and sound | conversion that occurs in TV's and computer screens |
electrical to heat | conversion that occurs in ovens |
chemical to heat and light | conversion that occurs when things burn |
