Police measur speed with a radar gun. It uses the Doppler effect to find speed. You can measure distance traveled and use a stopwatch to measure speed yourself.
You asked about velocity, however. Velocity is the combination of speed and direction. To measure velocity, you have to track the direction of travel. For that, either a compass, a chart or some other measure.

∙ 13y agoYou measure distance travel by an object and time it takes for the object to travel the distance. Divide first one one second and get average speed. Knowing the direction the object is traveling to allows you to build the vector of average velocity. Instantaneous velocity can be measure only as limit when traveled distance approaches zero.

What is the rate change in velocity?
The rate of change in velocity is known as acceleration.
How do you change a velocity joint in a 1996 Chevy Corsica?
The Rate of Change of velocity is - acceleteration
What is the rate of change of acceleration?
Velocity is the rate of change of position; acceleration is the rate of change of velocity; jerk is the rate of change of accelerationSee related link below for information on "Jerk"
Why does velocity represents rate of change of displacement?
Because that is the definition of velocity
Is the rate of your velocity change your acceleration?
yes
What do acceleration measures?
rate of change of velocity with respect to time.
Measures the changes in velocity?
A change in velocity is acceleration, so a accelerometer
What is rate of acceleration?
The rate of change of velocity. (As velocity is the rate of change of position.)
What is speed in calculus?
Speed is an example of a rate of change. It is specifically the rate of change of distance over time.In calculus, speed is the absolute value of velocity. Velocity measures both speed and direction, while speed only measures speed. For example, if a car is driving backward with a speed of 90km/h, its velocity would be -90km/h because "backward" indicates a "negative" velocity.
Does velocity indicates how long it takes to get from one place to another?
Velocity does not indicate the length of time it takes for something to get from one place to another. Velocity measures the rate of change of the displacement.
Velocity indicates how long it takes to get from one place to another.?
Velocity does not indicate the length of time it takes for something to get from one place to another. Velocity measures the rate of change of the displacement.
What is the rate of Chang of velocity?
The rate of change of velocity is acceleration.
The velocity of an object is the rate of change of its position What is it?
Velocity is the rate of change of the position of an objec
What is the rate change in velocity?
The rate of change in velocity is known as acceleration.
Rate of change of velocity of a moving object?
The rate of change of velocity is termed acceleration.
What is the rate of charge of velocity?
I think you mean the "rate of CHANGE" of velocity. (If you don't, then the question is meaningless.) The rate of change of velocity is called " acceleration ".
What is aceleration velocity?
"Acceleration velocity" is a meaningless phrase. "Velocity" is the time rate of change of position. "Acceleration" is the time rate of change of velocity.
