Term
| Law of Conservation of Energy |
|
Definition
| "States that energy cannot be created or destroyed, but can only be transformed from one form into another" |
|
|
Term
| Transferring Kinetic Energy |
|
Definition
| Kinetic energy can be transferred from one object to another when they collide. |
|
|
Term
|
Definition
| Energy that is stored due to position |
|
|
Term
|
Definition
| "Ability to cause change; can change the speed, direction, shape, or temperature of an object" |
|
|
Term
| Converting Kinetic to Potential Energy |
|
Definition
| Kinetic energy is transformed into potential energy when an object slows down and stops moving. |
|
|
Term
| Relationship between mass & kinetic energy |
|
Definition
| The amount of kinetic energy an object has depends on the mass of the object. More mass = more kinetic energy. |
|
|
Term
| Increasing Potential Energy |
|
Definition
| "The higher an object is lifted, the greater its potential energy." |
|
|
Term
| Relationship between speed & kinetic energy |
|
Definition
| "Kinetic energy depends on speed. The faster an object moves, the more kinetic energy it has. Kinetic energy increases as speed increases." |
|
|
Term
|
Definition
| Energy an object has due to its motion |
|
|
Term
|
Definition
| Occurs if energy changes from one form to another. Energy transformations go on all around you and inside of you all the time. |
|
|
Term
| Converting Potential to Kinetic Energy |
|
Definition
| Potential energy is transformed into kinetic energy when an object starts to move. |
|
|
Term
|
Definition
| Measure of the average kinetic energy of an object's atoms |
|
|
Term

|
|
Term
| What are freezing and boiling points in the Celsius scale? |
|
Definition
Freezing point is 0 degrees
Boiling point is 100 degrees |
|
|
Term
|
Definition
| Transfer of energy from one object to another due to a difference in temperature |
|
|
Term
| What are the 7 forms of energy? |
|
Definition
| Light, heat, chemical, nuclear, mechanical, electrical, and sound |
|
|
Term
|
Definition
| transfer of energy by collisions between atoms; usually occurs in solids |
|
|
Term
|
Definition
| transfers heat when particles move between objects or areas that differ in temperature; most common in gases and liquids |
