How to calculate velocity time graphs

To calculate the velocity at a specific time from a velocity-time graph, you can follow these steps:

1. Look at the graph and identify the point on the x-axis where the time is located.
2. Find the corresponding point on the graph that represents the velocity at that time.
3. Determine the value of the velocity at that point on the graph.
4. If the velocity is constant over a period of time, you can calculate the velocity by dividing the displacement by the time interval.

You can also calculate the average velocity over a period of time by dividing the change in displacement by the change in time.

Overall, interpreting and analyzing a velocity-time graph involves understanding the slope and shape of the graph to determine the velocity at any given point or over a specified time interval.
