Final answer:
Position-time graphs are used to show the relationship between an object's position and time. They help analyze velocity, displacement, and acceleration.
Step-by-step explanation:
Position-time graphs are used when studying physical position, distance, and displacement. These graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis). By analyzing these graphs, we can determine the object's velocity, displacement, and even acceleration. For example, a straight line on a position-time graph indicates constant velocity, while a curved line indicates changing velocity.
