|---|---|---|---|---|---|
| acceleration | the rate of change of velocity over time
🗑

| uniform acceleration | see constant accelertaion
🗑
|
||||
| air resistance | the resisting effect on a moving object due to friction of air.
🗑
|
||||
| delta | the symbol that indicates the difference or change between two quantities.
🗑
|
||||
| slope | a line's vertical change divides by its horizontal change
🗑
|

| time of flight | the elapsed time an object or projectile spends in the air
🗑

| m/sec^2 | a metric unit of measure for velocity
🗑
|

| free fall | movement that is due only to the force of gravity.
🗑
|
||||
| friction | the force that opposed the relative motion of bodies.
🗑
|

| initial speed | the speed an object has at the beginning of an experiment
🗑
|
||||
| term | a component of an equation
🗑
|
||||
| terminal speed | maxium speed reached by an object in free fall; the speed at which forces of gravity and air resistance are equal
🗑
|
||||
| constant acceleration | an accerelation that does not change; it is due to a velocity that changes at a constant rate
🗑
|
||||
| acceleration due to gravity(g) | the acceleration of anobject due to earth's gravitational field strength;equal to 9.8 m/sec^2 on earth
🗑

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.
