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