WebAverage velocity is displacement (change in position) divided by the time of travel, v - = Δ x Δ t = x f − x 0 t f − t 0, 2.5. where v - is the average (indicated by the bar over the v) velocity, Δ x is the change in position (or displacement), and x f and x 0 are the final and beginning positions at times t f and t 0, respectively. If ... WebDescription of Motion in One Dimension. Motion is described in terms of displacement (x), time (t), velocity (v), and acceleration (a). Velocity is the rate of change of displacement and the acceleration is the rate of change of velocity. The average velocity and average acceleration are defined by the relationships: Weban object's location or place. Motion. the change in an object's position as compared to objects around it. Speed. the measure of the distance an object travels in a certain amount of time. How speed is measured. by DISTANCE (how far you travel) and TIME (how long) Speed equation.
