|---|---|---|---|---|---|
| How can you tell teh acceleration of a car on a speed time graph? | The slope of the line indicates the acceleration
🗑
|
||||
| What is high positive value? | Rapidly increasing speed ( a line with a steep slope)
🗑
|
||||
| What is low positive value? | Slowly increasing speed ( a line with hardly any slope)
🗑
|
||||
| What is Zero value? | There is no acceleration ( there is a horizontal line across the graph)
🗑
|
||||
| What is negative value? | The speed is decreasing ( the slope is negative)
🗑
|
||||
| What does the area under the speed time graph indicate? | The area under the line ona speed time graph is the total distance traveled.
🗑
|
||||
| How can you tell that an object is accelerating? | As long as there is a slope to the lone the object is accelerating
🗑
|
||||
| What is Instantaniouse speed? | Is the sped at the particular moment in time, for any object moving a constant speed the instantaniouse speed is the same
🗑
|
||||
| How do you find intantaniouse speed on a distance time graph? | A target is a straight line that just touches the slope of time on that line, the slope of this line is the instantaniouse speed
🗑
|
||||
| How do you find the instantaniouse speed on a speed time graph? | For the speed time graph you just go straight down from the moment in which you want to find the speed for.
🗑
|
||||
| How do you find the instantaniouse speed on a distance time graph if the speed is changing? |
🗑
|
||||
| General formula for average speed | Vav = delta d/ delta t
🗑
|
||||
| General formula for average acceleration | Aav = delta v/ delta t
🗑

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.
