Position in physics refers to the location of an object in space. It is typically measured relative to a reference point or origin.
Velocity is calculated by dividing the change in position (displacement) by the change in time. It is a vector quantity, meaning it has both magnitude and direction.
The relationship between position, velocity, and time is described by the fundamental equation of kinematics: position = initial position + velocity * time. This equation shows how an object's position changes over time as a result of its velocity.
To plot a position-time graph, you would plot the object's position on the y-axis and time on the x-axis. The resulting graph would show how the object's position changes over time.
Average velocity is the total displacement of an object divided by the total time taken, while instantaneous velocity is the velocity of an object at a specific moment in time. Average velocity gives an overall picture of an object's motion, while instantaneous velocity is more specific and can vary throughout the object's motion.
