P-T Graphs

Front

What is a P-T graph?

Back

A P-T graph, or position-time graph, is a visual representation of an object's position over time, showing how far it has traveled at different moments.

Front

What does a horizontal line on a P-T graph indicate?

Back

A horizontal line indicates that the object is at rest, meaning its position is not changing over time.

Front

What does a positive slope on a P-T graph represent?

Back

A positive slope indicates that the object is moving away from the starting point, showing an increase in position over time.

Front

What does a negative slope on a P-T graph indicate?

Back

A negative slope indicates that the object is moving back towards the starting point, showing a decrease in position over time.

Front

How can you determine the speed of an object from a P-T graph?

Back

The speed can be determined by calculating the slope of the line on the graph; steeper slopes indicate higher speeds.

Front

What does a steep slope on a P-T graph signify?

Back

A steep slope signifies that the object is moving quickly, covering a large distance in a short amount of time.

Front

What does a flat line on a P-T graph represent?

Back

A flat line represents a period of time where the object is stationary, with no change in position.

Front

How can you identify when an object is stopped on a P-T graph?

Back

An object is stopped when the graph shows a horizontal line, indicating no change in position over time.

Front

What does it mean if a P-T graph has a curve?

Back

A curve on a P-T graph indicates that the object's speed is changing; it may be accelerating or decelerating.

Front

What is the significance of the y-axis on a P-T graph?

Back

The y-axis represents the position of the object, showing how far it is from the starting point at any given time.
