|---|---|---|---|---|---|
| accelerate | rate at which the velocity changes
🗑
|
||||
| acceleration includes | rate of slowing down, speeding up, going backwards and turning
🗑
|
||||
| Acceleration formula | final velocity-starting velocity
time it takes to change velocity
🗑
|
||||
| Acceleration is expressed as | (m/s/s)
🗑
|
||||
| increase in speed | positive acceleration
🗑
|
||||
| decrease in speed | deceleration
🗑
|
||||
| Motion is calculated by using a | reference point
🗑
|
||||
| speed is | the distance traveled and how long it took you to get there
🗑
|
||||
| speed average formula | total distance
total time
🗑
|
||||
| velocity | the rate of an object going in a certain direction
🗑
|
||||
| velocity always includes | change in direction
🗑
|
||||
| circular acceleration is called | centripetal acceleration
🗑
|
||||
| scientists use newton's to measure | force
🗑
|
||||
| force doesn't always cause something to | move
🗑
|
||||
| Force means | to push or pull
🗑
|
||||
| net force | the result of combining all the forces put on an object
🗑
|
||||
| net force formula | larger net force- smaller net force =the final direction
🗑
|
||||
| Unbalanced forces cause |
🗑
|
||||
| objects can move when | unbalanced forces are removed
🗑
|
||||
| friction | a force that opposes motion of two touching surfaces
🗑
|
||||
| friction is increased by | rougher surfaces
🗑
|
||||
| turning an object into a different position does not effect the | amount of friction
🗑
|
||||
| Sliding friction | friction caused by two surfaces sliding past each other
🗑
|
||||
| Rolling friction | wheels on another surface
🗑
|
||||
| fluid friction | opposes movement through fluids
🗑
|
||||
| static friction | opposes motion
🗑
|
||||
| lubricants | used to reduce friction
🗑
|
||||
| gravity | attraction of two or more objects
🗑
|
||||
| law of gravity | crated by newton
🗑
|
||||
| gravity force increases | mass increases
🗑
|
||||
| gravity decreases | distance
🗑
|
||||
| weight | measurement of gravity
🗑
|
||||
| mass | measurement of matter
🗑

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.
