|---|---|---|---|---|---|
| Force | A push, pull, or change in direction
🗑
|
||||
| magnitude | the strength of a force (greater magnitude = bigger force)
🗑
|
||||
| gravity | the force of 1 object with mass pulling on another object with mass
🗑
|
||||
| mass | the amount of "stuff" or matter in an object
🗑
|
||||
| Newtons | The unit of measurement for force (N)
🗑
|
||||
| Acceleration | speeding up, slowing down, or changing direction
🗑
|
||||
| Speed | Distance divided by time or how far an object travels in a certain amount of time (Units = m/s or any distance/time)
🗑
|
||||
| Friction | A force that exists between two objects and is always the opposite of motion.
🗑
|
||||
| Balanced Force | When an object is not moving or moving with constant speed
🗑
|
||||
| Unbalanced Force | When an object is accelerating (speeding up, slowing down, or changing direction)
🗑
|
||||
| Newton's 1st Law | The Law of Inertia - an object that is moving will keep moving and an object at rest will stay at rest UNLESS another force acts on the object
🗑
|
||||
| Newton's 2nd Law | F=m x a When mass increases, force will increase. When acceleration increases, force will increase.
🗑
|
||||
| Newton's 3rd Law | For every force there is another force acting in the opposite direction but equal in size
🗑
|
||||
| Net Force | The difference between forces acting in opposite directions or combined forces if acting in the same direction
🗑
|
||||
| inertia | an object wants to keep doing what it is doing (stay still or move) unless another force acts on the object
🗑
|
||||
| motion | a change in the position of an object compared to another object (moving)
🗑
|
||||
| position | specific point in space
🗑
|
||||
| center of mass | The point around which an object balances
🗑

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.
