Also, how do you find instantaneous velocity from a position-time graph?

Average velocity is the total displacement of an object divided by the total time taken. It is a measure of an object's overall motion over a certain period of time.
A position-time graph is a visual representation of an object's position over a period of time. It shows how an object's position changes over time and can be used to determine its velocity.
To find average velocity from a position-time graph, you need to calculate the slope of the line connecting the initial and final positions. This can be done by dividing the change in position by the change in time.
Average velocity is typically measured in units of distance per time, such as meters per second (m/s) or kilometers per hour (km/h).
Yes, average velocity can be negative if the object's displacement is in the opposite direction of its initial position. A negative average velocity indicates that the object is moving in the opposite direction of its initial position.
