||||
| decreasing friction | smoother surfaces
🗑
|
||||
| rolling forces | the friction between rolling object and the surface it rolls on.
~only a small point of contact(wheel will roll on contact)
🗑
|
||||
| static forces | friction between 2 surfaces that are not moving past each other.
🗑
|
||||
| sliding | the force that opposes the motion of 2 surfaces sliding past each other.
🗑
|
||||
| fluid forces | when an object is moving through liquid or gases
🗑

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.
