B: Physics = Changes in Motion 1.4 Graphical Description of Uniform Motion Flashcards
What does a position-time graph depict?
Location changes over time
The graph shows how an object’s position varies with time.
How can you determine average velocity from a position-time graph?
By calculating the slope of the graph
The slope represents the change in position over the change in time.
In a position-time graph, what does a positive slope indicate?
The object is moving away from the starting point
A positive slope indicates an increase in position over time.
In a position-time graph, what does a negative slope indicate?
The object is moving towards the starting point
A negative slope indicates a decrease in position over time.
Fill in the blank: Average velocity can be determined from a position-time graph by calculating the _______.
slope

Fill in the blank: Average velocity can be determined from a position-time graph by calculating the _______.
slope
What is the equation for displacement in terms of average velocity?
Displacement equals the velocity multiplied by the elapsed time
In the context of a velocity-time graph, what does velocity multiplied by elapsed time represent?
The area between the velocity graph and the horizontal line at v=0 on the velocity-time graph
Fill in the blank: Displacement can be calculated using the formula: Displacement = _______ x elapsed time.
[average velocity]
True or False: The area under the velocity-time graph represents the displacement.
True
