|---|---|---|---|---|---|
| Motion | change in position
🗑
|
||||
| Force | a push or pull with a size and direction
🗑
|
||||
| Acceleration | when an object speeds up, slows down, or turns.
🗑
|
||||
| Inertia | measures the tendency of an object to remain at rest or keep moving.
🗑
|
||||
| Newton's 1st Law | object remains at rest or moves in a straight line with constant speed unless a force acts on it
🗑
|
||||
| Newton's 2nd Law | an object acted on by an unbalanced force will accelerate in the direction on the force
🗑
|
||||
| Newton's 3rd Law | forces always act in equal but opposite pairs
🗑
|
||||
| Balanced Forces | forces are equal but in opposite directions, canceling each other out
🗑
|
||||
| Unbalanced Forces | When one force is greater than another, a change in motion (acceleration) will result.
🗑
|
||||
| Weight | the force of gravity on an object; weight = mass X 9.8 m/s2 (acceleration due to gravity)
🗑
|
||||
| Acceleration due to gravity | 9.8 m/s2
🗑
|
||||
| Contact Forces | involves objects touching each other
🗑
|
||||
| Long Range or Non Contact Forces | forces that occur at a distance (grvity, magnetism, electricity)
🗑
|
||||
| Distance | entire path an object travels
🗑
|
||||
| Displacement | distance and direction between starting and stopping positions
🗑
|
||||
| Speed | distance traveled divided by the time needed to travel the distance or s = d/t
🗑
|
||||
| Relative Motion | an object's position change as described in terms of a reference point
🗑
|
||||
| Constant Speed | speed is the same at any given moment in time
🗑
|
||||
| Instantaneous Speed | speed at a particular instant in time
🗑
|
||||
| Friction | a force that resists motion
🗑
|
||||
| Velocity | displacement over a given time. (Speed with direction)per unit of time.
🗑
|
||||
| Mass | how much matter is in an object
🗑

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.
