Speed and Velocity. Speed is how fast something moves. Velocity is speed with a direction. Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity.

Average velocity if acceleration is zero and constant = Final velocity = a = acceleration t = time. Method 1. Finding Average Velocity. Download Article. 1.
Kids learn about speed and velocity in the science of physics and the laws of motion including units and measurement. What is the difference between speed and velocity?
Velocity is the rate of motion in a specific direction. I'm going that-a-way at 30 kilometers per hour. My velocity is 30 kilometers per hour that-a-way. Average speed is described as a measure of distance divided by time. Velocity can be constant, or it can change (acceleration). Speed with a direction is velocity.
Science uses a formula for the velocity of Velocity = the change in distance/change in time (or Velocity is equal to the change in distance divided by the change in time) Science uses the same measurement unit of meters per second as they use with speed = m/s.
In this formula, v a v g is the average 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 the starting time t 0 is taken to be zero, then the average velocity is written as below: v a v g = Δ x t.
