| energy | ability to do work or cause change
🗑
|
||||
| joule | SI unit for energy (and work)
🗑
|
||||
| transformation | change
🗑
|
||||
| kinetic energy | energy of motion (part of mechanical energy) KE + PE = mechanical
🗑
|
||||
| potential energy | energy of position (part of mechanical energy) KE + PE = mechanical
🗑
|
||||
| gravitational potential energy | same as Potential Energy- just referenced to its position above the earth; higher up it is, the more gravitational potential energy it has
🗑
|
||||
| law of conservation of energy | energy cannot be created nor destroyed; only changed or transformed into another form
🗑
|
||||
| reference point | place or object you are comparing motion to
🗑
|
||||
| motion | going from one point or position to another
🗑
|
||||
| magnitude | strength
🗑
|
||||
| vector | direction
🗑
|
||||
| speed | the rate at which motion occurs- distance compared to time; d/t
🗑
|
||||
| velocity | speed with direction
🗑
|
||||
| acceleration | rate at which velocity changes; compares starting and ending velocity divided by time

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.
