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.
