A "radar gun" is used by police to know the speed of fast moving vehicles.
Velocity is a vector. That means it has magnitude and direction. Its magnitude is same as speed.

What is a momentum of an object of mass 'm' moving the velocity v?
Momentum is mass times velocity. Note that velocity and speed are not exactly the same thing. Velocity is a term used in physics to define both the speed and the direction of a moving object, so if two objects are moving at the same speed but in opposite directions, they have opposite momentum.
What is the best resource for finding a used vehicle?
The best resource for finding a used vehicle is to use CarSoup. Otherwise check out and compare prices of your local used car dealership, but make sure a mechanic checks out the vehicle before you buy it.
What is vector and resultant velocity?
A vector is used to represent direction and magnitude of speed. Velocity is the speed of an object and a specification of its direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. Therefore a vector can be used to represent a velocity. The term "resultant velocity" implies a change in velocity which can be determined using vector analysis.
What is formulas finding speed and velocity?
velocity = distance / time There are also some formulae involving acceleration; for example, in the case of constant acceleration: velocity = initial velocity + acceleration x time If the acceleration is not constant, an integral is used instead.
What is the purpose of the braking system?
It is used for slowing or stopping a moving vehicle.
What is the purpose of the brakeing system?
It is used for slowing or stopping a moving vehicle.
What type of mirror used in a view finding mirror of a vehicle?
convex mirro
What word is used to show an objects tendency to remain at rest or keep moving with constant velocity?
Inertia
When can the equations of kinematics not be used?
Equations of kinematics or equations of motion can not be used when the body is not accelerating or is moving with a constant velocity.
Can velocity be 0 but speed not 0?
Speed and Velocity are two words that mean the same. You may mean, "Can Velocity be 0 but acceleration not 0". Yes, this occurs when a moving object is changing direction (say from moving forwards to moving backwards) or is just about to move or, at that very instant has just come to a halt. In all these cases, speed /velocity is zero but the body is accelerating. Don't forget, the word acceleration is also used when an object is decelerating (slowing down).
When were roller bearings used?
The Roller bearings can be used at all the places where the severe loading is applied at high velocity between two moving parts
What is the definition of velocity?
Velocity is a measure of the speed of an object that is moving in a specific direction.Imagine walking across the room. If you walk in the same direction and do not change speed, your velocity remains constant until you stop moving. If you keep a constant speed, but change direction while walking, your velocity changes. If you walk in the same direction but slow down and speed up while walking, your velocity changes. Velocity is a vector quantity that describes the speed and direction that an object is moving. It is the same as "speed" except that it includes the direction of the object as well. Speed is the rate of change of distance.In common language, velocity is often used imprecisely to mean "speed".
