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
What can be said of the motion of an object when the signs of the velocity and acceleration are the same? 

Definition


Term
What can be said of the motion of an object when the signs of the velocity and acceleration are different?

Term
Describe the motion of a stone at it's peak in terms of position. 

Definition


Term
Describe the motion of a stone at it's peak in terms of velocity. 

Definition


Term
Describe the motion of a stone at it's peak in terms of acceleration.

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? 

Definition


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).
