|---|---|---|---|---|---|
| Force | a push or a pull exerted on an object; force has size and direction
🗑
|
||||
| Static friction | the force that resist the start of sliding motion between two surfaces that are contacted and at rest
🗑
|
||||
| Kinetic friction | the force that opposes the movement of two surfaces that are in contact and are moving over each other
🗑
|
||||
| Drag | a force parallel to the velocity of the flow; it opposes the direction of an aircraft and, in combination with thrust, determines the speed of the aircraft.
🗑
|
||||
| Field | any region in which a physical force has an effect
🗑
|
||||
| Net Force | the combination of all of the forces acting on an object
🗑
|
||||
| Inertia | the tendency of an object to resist a change in motion unless an outside force acts on the object
🗑
|
||||
| Gravity | a force of attraction between two objects that is due to their masses
🗑
|
||||
| Free fall | the motion of a body when only the force of gravity is acting on the body
🗑
|
||||
| Orbit | the path that a body follows as it travels around another body in space
🗑
|
||||
| Electric Charge | a fundamental property that leads to the electric magnetic interactions among particle that make up matter
🗑
|
||||
| Static electricity | electric charge at rest; generally produce by friction or induction
🗑
|
||||
| Electrical conductor | a material in which charges can move freely
🗑
|
||||
| Electrical insulator | a materiel in which charges can not move freely
🗑
|
||||
| semiconductor | an element or compound that conducts electric current better than an insulator does but not as well as a conductor does.
🗑

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.
