| Newton's first law of motion | objects at rest remain at rest and objects
in motion will stay in motion with the same velocity, unless acted on by an
unbalanced force
🗑

🗑
|
||||
| Newton's third law of motion | everytime one object exerts a force on another object the second object exerts a force that is equal in size and opposite in direction back on the first object
🗑
|
||||
| mass | is the number of particalesin an object
🗑
|
||||
| weight | measure of force of gravity changed by location
🗑
|
||||
| inertia | the resistance of an object to change in the speed or the direction of its motion
🗑
|
||||
| air resistance | a type of fluid friction experienced by objects falling through the air
🗑
|
||||
| balanced forces | equal force of opposite directions acting on an ibject that doesn't cause motion
🗑
|
||||
| unbalanced forces | unequal forces which cause and object to move or to have motion

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.
