Understanding Motion Graphs
Click on the flashcard to see the answer
What is a motion graph?
A motion graph is a graphical representation of an object's movement, showing how its position or speed changes over time.
What are the two main types of motion graphs?
Position-time graphs and velocity-time graphs.
In a position-time graph, what does the slope represent?
The slope represents the object's velocity.
How can you determine acceleration from a velocity-time graph?
The slope of a velocity-time graph represents the object's acceleration.
What does a flat line on a position-time graph indicate?
A flat line indicates that the object is at rest or not changing its position over time.
What does a steep slope on a position-time graph indicate?
A steep slope indicates a higher velocity, meaning the object is moving faster.
How do you interpret a curve on a position-time graph?
A curve indicates changing velocity, meaning the object is accelerating or decelerating.
What does a flat line on a velocity-time graph represent?
A flat line indicates constant velocity.
What kind of motion does a negative slope on a velocity-time graph represent?
A negative slope indicates deceleration or motion in the opposite direction.
What does the area under a velocity-time graph represent?
The area under a velocity-time graph represents the displacement of the object.
How does a positive slope on a velocity-time graph affect the motion of an object?
A positive slope indicates the object is accelerating.
Can motion graphs show non-linear motion, and if so, how?
Yes, curved lines on either type of motion graph indicate non-linear motion such as changes in speed or direction.
What might cause an upward curve on a position-time graph?
An upward curve could result from accelerating motion, where the object is moving faster over time.
On a velocity-time graph, what does a downward curve represent?
A downward curve represents decreasing acceleration or deceleration.
How can you tell if an object is returning to its starting point using a position-time graph?
The object returns to its starting point if the position line moves back down to the horizontal axis (time = 0) after climbing upwards.
