|---|---|---|---|---|---|
| force | a push or a pull
🗑
|
||||
| balanced forces | forces on an object that combine to give a zero net force and do not change the motion of the object
🗑
|
||||
| unbalanced forces | the forces acting on a object that cause a change in velocity; making the object speed up, slow down, or change direction
🗑
|
||||
| net force | the combination of all forces acting on an object
🗑
|
||||
| at rest | a speed of zero
🗑
|
||||
| speed | distance divided by time
🗑
|
||||
| direction | the path that an object is moving or facing
🗑
|
||||
| motion | a change in an object's position
🗑
|
||||
| friction | the force that opposes the motion of one surface as it moves across another surface
🗑
|
||||
| velocity | speed with direction
🗑
|
||||
| distance | size of the gap between two places
🗑
|
||||
| rate | a comparison of two quantities measured in different units
🗑
|
||||
| acceleration | a change in velocity (speed or direction)
🗑
|
||||
| Newton's 1st law | an object in motion tends to stay in motion & an object at rest stays at rest unless acted upon by an outside force.(Law of Inertia)
🗑
|
||||
| Newton's 2nd law | the acceleration of an object depends on the mass of the object and the amount of force applied (F=ma)
🗑
|
||||
| Newton's 3rd law | For every action there is an equal and opposite reaction
🗑
|
||||
| inertia | the tendency of an object to resist any change in its motion
🗑
|
||||
| magnitude | The great size or importance of something
🗑
|
||||
| action | movement caused by a force
🗑
|
||||
| reaction | resistance or opposition to a force, influence or movement
🗑
|
||||
| law of conservation of energy | the law that states that energy cannot be created or destroyed but can be changed from one form to another
🗑

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.
