To find the average velocity of an object from a position-time graph, you can use the formula:
Average Velocity = Total Displacement / Total Time
Here's how you can determine the average velocity from a position-time graph:
Determine the initial position and final position: Identify the positions of the object at the beginning and end of the time interval for which you want to find the average velocity.
Calculate the total displacement: Find the difference between the initial position and the final position. If the object moves in a straight line, the displacement will have a direction (positive or negative).
Total Displacement = Final Position - Initial Position
Determine the total time: Identify the time interval between the initial and final positions on the graph.
Calculate the average velocity: Divide the total displacement by the total time.
Average Velocity = Total Displacement / Total Time
Note: Make sure to use the appropriate units for position (e.g., meters) and time (e.g., seconds) to ensure the correct units for average velocity (e.g., meters per second).
By following these steps, you can find the average velocity of an object based on a position-time graph.
