Velocity is the speed of an object plus its direction. Speed is called a scalar quantity and velocity is a vector quantity. Speed of Light. The fastest possible speed in the universe is the speed of light. The speed of light is 299,792,458 meters per second.
When you accelerate or decelerate, you change your velocity by a specific amount over a specific amount of time. Just as with velocity, there is something called instantaneous acceleration. Instantaneous means scientists measure your acceleration for a specific moment of time.

It can be used as homework or to provide extra practice calculating speed to struggling students. Learn More: Great Schools. 3. Speed Challenge.
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.
Velocity. Velocity is a bit trickier. It is the rate of change in an object’s position. Velocity has a direction and a magnitude (speed) and is therefore considered to be a vector. 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 ...
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt. Created by Sal Khan. Questions.
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.
