Term
Using graphs, how can you find the average speed of an object? |
|
Definition
The slope of a distance versus time graph is equal to the average speed of an object. |
|
|
Term
Using graphs, how can you find the instantaneous speed of an object? |
|
Definition
Create a line on the point tangent to the rest of the distance vs. time graph and find it's slope. |
|
|
Term
Using graphs, how can you find the acceleration of an object? |
|
Definition
Find the slope of a velocity (or speed) versus time graph. |
|
|
Term
Using a graph, how can you find the instantaneous acceleration of an object? |
|
Definition
Find the slope of a line on that particular point, tangent to the velocity (or speed) vs. time graph. |

Term
When is an object in free fall? |
|
Definition
When gravity is the only force working against It. |
|
|
Term
We often approximate falling objects as being in freefall. Why is this not correct? |

Term
What is the relationship between velocity and speed? |
|
Definition
Both measure how fast and are measured in m/s. But velocity includes direction (negative or positive). |
