What is energy? |
The ability or capacity to do or preform work |
|
|
What is work? |
The transfer of energy |
|
|
What happens when an object does work on another? |
Energy is transferred from the first object to the second |
|
|
What is Kinetic energy? |
Energy in motion. All moving objects have kinetic energy |
|
|
What is the equation to find kinetic energy? |
Mass x velocity (speed) squared divided by 2 |
|
|
What is the equation for potential energy? |
mass x acceleration (always 9.8) x distance |
|
|
What is potential energy? |
Energy an object has because of its position |
|
|
What type of energy is both kinetic and potential? |
Mechanical energy |
|
|
What are the types of potential energy? |
Chemical, elastic, gravitational, and nuclear |
|
|
What are the types of kinetic energy? |
Electrical, radiant, thermal, sound, and light |
|
|
What is radiant energy? |
Energy that comes from the waves of the electromagnetic spectrum |
|
|
What is thermal energy? |
Kinetic energy due to the random motion of particles that make up an object |
|
|
More particles = what? |
More thermal energy |
|
|
What is sound energy? |
Energy caused by an objects vibrations |
|
|
What is light energy? |
Energy produced by vibrations of electrically charged particles |
|
|
What is mechanical energy? |
The total energy of motion and position of an object |
|
|
What are the types of potential energy? |
Chemical, elastic, gravitational, nuclear, and mechanical |
|
|
What is elastic energy? |
Energy that stores when an object changes from its original shape so it can change back |
|
|
What is gravitational energy? |
The amount of work done on an object to lift it up to a certain height |
|
|
What is nuclear energy? |
Energy that comes from the changes in the nucleus of an atom |
|
|
What is Fission? |
When a nucleus of a heavy element is split the potential energy in the buckets is given off |
|
|
What is chemical energy? |
Energy of a compound that changes as its atoms are rearranged |
