|---|---|---|---|---|---|
| Acceleration | the rate at which velocity changes over time; an object accelerates if its speed, direction or both change
🗑
|
||||
| Average Speed | the total distance traveled divided by the total time taken
🗑
|
||||
| Balanced Forces | a set of forces on an object that cancel one another out so that there is no overall force on that object; the combined force is the same as zero force; balanced forces will not cause a change in the motion of an object
🗑
|
||||
| Displacement | the change in position in an object
🗑
|
||||
| Force | a push or pull exerted on an object in order the change the motion of the object; force has size and direction
🗑
|
||||
| Friction | a forces that opposes motion between surfaces that are in contact
🗑
|
||||
| Inertia | the tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction
🗑
|
||||
| Instantaneous Speed | the rate of motion at a particular instant in time
🗑
|
||||
| Motion | an object's change in position relative to a reference point
🗑
|
||||
| Net Force | the combination of all the forces acting on an object
🗑
|
||||
| Newton's Laws of Motion | a series of laws developed by Isaac Newton that describe the relationship between force and motion
🗑
|
||||
| Newton | the SI unit for force (symbol, N)
🗑
|
||||
| Position | the location of an object
🗑
|
||||
| Reference Point | a location to which another location is compared
🗑
|
||||
| Speed | a measure of how fast something moves; rate of motion
🗑
|
||||
| Unbalanced Forces | a set of forces exerted on an object that change the motion of that object; the combined force has size and direction; unbalanced forces are needed to make an object start moving, speed up, slow down or change direction
🗑
|
||||
| Vector | a quantity that has both size and direction
🗑
|
||||
| Velocity | the speed of an object in a particular direction
🗑
|
||||
| Velocity | the speed of an object in a particular direction
🗑

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.
