speed =dist/time
velocity=displacement/time
difference is that velocity depicts the direction in which a body is moving as displacement is one of it"s attriebutes but speed does not

What is the Difference between velocity and average speed?
speed is a scalar quantity ie it has no directions...........whereas velocity is a vector quantity ie it has directions...................Also speed has distance n velocity has displacement
The rate at which 'n' object moves is called?
Speed. Perhaps also velocity, although the rigorous definition of velocity includes direction (a vector).
What would be the velocity of ball which is thrown by the man who running at the speed equal to the velocity of light?
As velocity never exceeds the velocity of light.... so i hope a man running with the velocity of light will not be able to throw a ball with any velocity.......... we may get the maximum n minimum velocity with which that can be thrown mathematically that we may get it to be zero................
What is refractive index of a lens?
The ratio of the velocity of light in a vacuum to that in a medium is the refractive index of a lens. It is represented by n = c/v, where n = refractive index , v = characteristic speed and c = speed of light 299792 kmsec-1 or 1 Planck speed.
How do you calculate angular velocity RPM for lathe when given cut lenght dia workpiece tool pressure and cutting surface speed?
V = Cutting speed N = RPM d = Diameter in millimeters N = 1000.V / d . 3.14
Are momentum and speed the same thing?
NO .Momentum has some potential to do work where as speed is only the rate of action or travel. For example if a car is switched off while speeeding itwill still continue to run for some time due to momentum. Speed by itself has no energy for doing work Momentum is in fact defined as mass x velocity, and will be conserved in an elastic collision.
What is the difference between a G wireless and a N wireless router?
Speed and technology (N is a newer, faster technology.)
What is velocity at starting point when it tries to attain terminal velocity?
i think its velocity is min n its try to attain max. velocity which is terminal velocity...what say?
The distance moved by an object divided by the time it took to move that distance is defined as?
As this has already been answered I will answer it again. The answer is called "Speed" because there is no direction given. If you were to travel at 45kl/h in a straight line, and then change to a N/W direction, then this would be known as your velocity even though you may still be travelling at 45kl/h.
A force of 320 N is required to pull a box across the floor at a constant velocity What is the force of friction between the floor and the box?
It's 320 N. Since the friction force is in the direction opposite to the motion, thepulling force and the friction force balance, the net horizontal force on the box iszero, and its speed is therefore constant.
Driving along a road at a constant velocity of 100km h-1.the forces opposing the motion of the car total 800N. cars mass is 1200kg.what force do you need to maintain constant velocity?
It doesn't matter what the car's mass is, or for that matter, what speed you're talking about.If the total forces opposing its motion are 800 N, then you need to supply 800 N in the directionof motion in order to maintain a constant speed.
How do you calculate the change in velocity of a falling object?
The speed (magnitude of velocity) is always 9.8 meters per second (32.2 feet per second) greater than it was exactly one second earlier. If the object spent "N" seconds falling, then its speed (magnitude of velocity) is 9.8N meters per second (32.2N feet per second) greater at the bottom than it was at the top. The direction of velocity remains constant under the influence of gravity ... straight down.
