Term
|
Definition
the energy an object has due to its motion ex: ball thrown
not all objects have the same amount of kinetic energy |
|
|
Term
| the amount of kinetic energy |
|
Definition
is determined by the speed and mass of the object
the more mass the more kinetic energy or the more speed the more kinetic energy |
|
|
Term

|
Definition
|
|
Term
|
Definition
| energy that is stored because of an object's position ex: skier at the top of a hill |
|
|
Term

|
Definition
| elastic, gravitational, and chemical |
|
|
Term
|
Definition
| elastic can store energy and convert it to motion when it is released ex: sling shot |
|
|
Term
| Gravitational potential energy |
|
Definition
| the energy an object has when we raise it off the ground ex: ball dropping |
|
|
Term
| Chemical potential energy |
|
Definition
| the energy stored in the chemical bonds of molecules ex: battery |
|
|
Term
| Potential energy can be converted to |
|
Definition
| kinetic energy ex: skier at top of hill has potential energy then changes to kinetic as he moves down the hill. |
|
|
Term
| Water behind a dam is potential energy |
|
Definition
| the water released fro the dam is converted to kinetic energy |
|
|
Term
| Energy cannot be created or destroyed |
|
Definition
| only transformed from one form to another |
|
|
Term
|
Definition
| Energy can be converted from heat, light, electrical, mechanical, sound, chemical, magnetic ex: chemical from the battery to electrical in the wires to light in the bulb to heat energy. |
|
|
Term
|
Definition
| the transfer of energy from one object to another due to a difference in temperature |
|
|
Term
| the faster the molecules move the |
|
Definition
| higher the temperature and the more kinetic energy ex: boiling water |
|
|
Term
|
Definition
| chemical reaction compounds are broken down and new compounds are formed. ex: C + O2 = CO2 + heat |
|
|
Term
| In a chemical reaction energy can be given off as |
|
Definition
heat light electricity and sound
ex: battery, light bulbs and switch. What is chemical energy turned into...heat! |
|
|
Term
| Chemical reactions occur at different rates |
|
