| A scalar quantity that shows the linear dimension a object moved during a time interval. | distance
🗑
|
||||
| A numeric amount that describes the total distance and direction of motion. It is shown graphically with a vector whose tail is the starting point and the tip is the end point. | displacement
🗑
|
||||
| A system of reference points and coordinate axis from which the position and motion of an object can be determined. | frame of reference
🗑
|
||||
| The span of time during which a phenomenon is observed. It is calculated by final time minus initial time. | interval
🗑
|
||||
| The branch of mechanics that describes how things move. It includes measurements and calculations of velocity, acceleration, position, time, and displacement within a frame of reference. | kinematics

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.
