| Question | Answer |
|---|---|
| energy | the aability to cause change |
| kinetic energy | is energy due to motion |
| potential energy | is stored energy due to the interactions between objects or particles |
| gravitational potentail energy | energy stored between an object and Earth depends on the objects weight and height |
| elastic potential energy | energy stored in objects that are compressed or stretched, such as spring or rubber band |
| chemical potential energy | is energy stored in the chemical bonds between atoms |
| work | is the transfer of energy that occurs when a force is aplied over a distance |
| mechanical energy | the total energy of an object or froup of objects due to large-scale motions and interactions |
| sound energy | the energy that sound carries |
| thermal energy | energy due to the motion of particles that make up an object |
| electric energy | is the energy that an electric current carries |
| radiant energy | the energy electromagnetic waves carry |
| nuclear energy | energy that is stored in the nucleus of an atom |
| Example of mechanical energy | the mechanical energy of a basketball increases when a player shoots the basketball |
| Example of sound energy | when you pluck a guitar string the string vibrates and produces sound |
| example of thermal energy | when you heat objects, you transfer thermal energy to those objects from their surroundings. **fire** |
| ecample of electric energy | and electric fan |
| example of radiant energy | sun gives off energy that travels to Earth as electomagnect waves **light waves, microwaves, and radio waves*** |
| example of nuclear energy | the sun, nuclear energy is released when nuclei join toghter. |
| law of conservation | energy can be transferred from one form into another, but energy cannot be created or destroyed. |
| nonrenewable energy resource | ia an energy that is abailbale in limited amounts or that is used faster than it is replaced in nature |
| fossil fuels | are the remains of ancient organisms that can be burned as an energy source |
| what are some fossil fuels | coal, petroleum, and natural gases |
