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
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
Speed. Perhaps also velocity, although the rigorous definition of velocity includes direction (a vector).
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................
At terminal velocity, the force of air resistance is equal in magnitude to the weight of the object. Since the weight of the bag of nails is 100 N, the air resistance on the bag of nails falling at terminal velocity is also 100 N.
V = Cutting speed N = RPM d = Diameter in millimeters N = 1000.V / d . 3.14
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.
Speed and technology (N is a newer, faster technology.)
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.
Kilometer per hour is a speed. A kilo is only a suffix to something. Whot does n. mean?
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.
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.
The two formulas commonly used to calculate the speed of a wave are: v = fλ (velocity equals frequency multiplied by wavelength) and v = d/t (velocity equals distance traveled divided by time taken). These formulas can be applied to different types of waves, such as sound waves or electromagnetic waves.
