|
||||
|---|---|---|---|---|---|
| Acceleration | The rate at which velocity changes
🗑
|
||||
| Can you predict if a car will go over hills or not based on your view of the potential energy of the car? | YES!
🗑
|
||||
| chemical potential energy | Energy stored in chemical bonds like when you eat food your cells use, or when the burning wood of a fire gives off light and heat
🗑
|
||||
| Does it matter HOW I get the potential energy stored? | Objects have the same potential to move when they are at rest, no matter how they arrived at that point. A ball on a hill could be moved by hand, moved by a machine, or placed there in any way, it still has the same potential energy to transfer
🗑
|
||||
| elastic gravitational potential energy | like a rubber band!
🗑
|
||||
| examples of potential energy | gas in a can, lifted hammer, ball at top of hill
🗑
|
||||
| Force | A push or pull exerted on an object
🗑
|
||||
| gravitational potential energy | Potential energy that depends on the height of an object, like Burt sliding down the hill!
🗑
|
||||
| heat | when you TRANSFER energy from potential to kinetic energy, we measure this transfered energy by measure for THIS....
🗑
|
||||
| Joule | the unit of measure for kinetic energy
🗑
|
||||
| kinetic energy | energy of motion; energy of doing work
🗑
|
||||
| Law of Conservation of Energy | the law that states that energy cannot be created or destroyed but can be changed from one form to another
🗑
|
||||
| Mass | the amount of matter in an object
🗑
|
||||
| measure | a tool used to find out about the energy in an object or its size
🗑
|
||||
| potential energy | stored energy, like a lifted hammer
🗑
|
||||
| releasing energy | like a bank, when you release energy you do not create or destroy it, you exchange it for other types of energy, as you would exchange money for items you buy
🗑
|
||||
| Speed | The distance an object travels per unit of time
🗑
|
||||
| storing energy | like a bank, when you store energy it has the potential to do more things
🗑
|
||||
| Temperature | A measure of the average kinetic energy of motion of the particles of a substance. Fast moving molecules = higher temps; slower molecules = colder temps
🗑
|
||||
| total energy | potential energy + kinetic energy
🗑
|
||||
| types of kinetic energy | Radiant, thermal, motion, sound, electrical; a rolling ball, for example is mechanical kinetic energy, things like fire,
🗑
|
||||
| work | Force exerted on an object that causes it to move
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
