A P-t graph represents the relationship between position (P) and time (t) for an object. It shows the change in position over a certain period of time.
Velocity is represented by the slope of the line on a P-t graph. The steeper the line, the greater the velocity, and the flatter the line, the lower the velocity.
A horizontal line on a P-t graph indicates that there is no change in position over time, meaning the object is at rest.
To determine the average velocity from a P-t graph, you can calculate the slope of the line between two points on the graph. The slope is equal to the change in position divided by the change in time.
Speed is the rate at which an object is moving, while velocity is the speed and direction of an object's motion. Velocity takes into account the direction of an object's movement, while speed does not.
