Final answer:
The average velocity of an object can be determined from a position-time graph by finding the slope of the graph. The slope of a position-time graph represents the rate of change of position over time, which is the velocity of the object.
Step-by-step explanation:
The average velocity of an object can be determined from a position-time graph by finding the slope of the graph. The slope of a position-time graph represents the rate of change of position over time, which is the velocity of the object. To find the average velocity, you need to calculate the change in position and the change in time over a given interval. The formula for average velocity is:
Average velocity = (change in position) / (change in time)
For example, if the position-time graph shows that the object traveled 10 meters in 2 seconds, the average velocity would be:
Average velocity = 10 meters / 2 seconds = 5 meters per second
