Velocity Diagram Physics. Since velocity is the change in position of the car during a corresponding time interval and we are free to select the time interval as the time interval between exposures on our multiple exposure photograph the velocity is simply the change in the position of the car between dots. 1 3 2 average velocity v a v e δ x δ t x f x o t f t o.
We therefore define a rate called the average velocity thus. In the top diagram the size of the velocity vector is constant so the diagram is depicting a motion of constant velocity. If the size of the arrow in each consecutive frame of the vector diagram is the same then the magnitude of that vector is constant.
We therefore define a rate called the average velocity thus.
Determining the velocity from a motion diagram. Since we know displacement is a vector of course in our current simple 1 dimensional model it can only have two directions then average velocity must be a vector as well. The length and the. Velocityis the measurement of the rate and direction of change in the position of an object.
