|---|---|---|---|---|---|
| Force | show 🗑
|
||||
| show | a force that directly touches an object.
🗑
|
||||
| show | a force that is not touching an object; has a field that weakens with distance.
🗑
|
||||
| Types of contact forces | show 🗑
|
||||
| show | gravity, magnetism, electricity
🗑
|
||||
| Friction | show 🗑
|
||||
| show | a push or a pull force.
🗑
|
||||
| show | a force perpendicular to the point of contact.
🗑
|
||||
| show | force of attraction between two masses.
🗑
|
||||
| show | force of attraction between two charged particles.
🗑
|
||||
| show | movement of electrons that creates a magnetic field around a conductor.
🗑
|
||||
| show | perpendicular to a surface; only works in contact to a surface.
🗑
|
||||
| Items to describe frictional force | show 🗑
|
||||
| show | a push or a pull; works parallel to the surface; can work without gravity;
🗑
|
||||
| Items to describe gravitational force | show 🗑
|
||||
| show | increases with mass; decreases with distance; stronger at the poles; weaker along the sides; typically metals.
🗑
|
||||
| show | increases with mass; decreases with distance; stronger at the poles; weaker along the sides; can turn metals into a magnet; jumping electrons.

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.
