Select the option that best summarizes the reason for the use of position-time graphs when studying physical science.

• Position-time graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis) to show velocity.
• Position-time graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis) to show displacement.
• Position-time graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis) to show acceleration.
• Position-time graphs show the relationship between the position of an object (shown on the x-axis) and the time (shown on the y-axis) to show displacement.

Option 1: Position-time graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis) to show velocity.

This option best summarizes the reason for the use of position-time graphs when studying physical science. By analyzing the slope of the graph, it is possible to determine the velocity of the object.
