Speed and velocity are similar because they are both measures of quantity that involve motion. They differ because speed is a scalar quantity while velocity is a vector.
When a direction is specified, it is called velocity. When the direction is not specified, it is called a speed. (That's the difference between a vector and a scalar.)
Simply put,acceleration is got when velocity changes with time while velocity is when speed changes with time.
Velocity is a speed and its direction. -- "30 miles per hour" is a speed -- "30 miles per hour north" is a velocity -- "30 mph north" and "30 mph east" are equal speeds but different velocities.
That is the speed or velocity.That is the speed or velocity.That is the speed or velocity.That is the speed or velocity.
Velocity is a vector measurement, it has both a speed quantity, but also includes direction. Speed is a scalar measurement, it only concerns with the how fast the object is moving, not its direction
Speed is the rate of covering distance. 60 mph north, south, or west are all exactly the same speed. Velocity is speed and its direction. 60 mph north, south, and east are three different velocities.
Velocity is speed along with the direction of the speed.
velocity is speed with direction; velocity is a vector and speed is a scalar
velocity is speed in a direction
Speed has no direction, velocity does.
Velocity and speed are not synonyms.
SPEED has the speed only; while VELOCITY has the direction and the speed.
Speed is scalar quantity and velocity is a vector - velocity has both speed AND direction (You might say that velocity is speed with an attitude!)
Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
I would think direction since velocity is a vector. Could also be speed. Speed is just a rate, velocity has speed and a direction. Short answer: direction with a speed caveat to account for the ambiguity in the question.
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
Well velocity is basically the same thing as speed but with direction (velocity can be negative or positive and speed is always positive). l velocity l = speed So a change in velocity means a change in speed.
That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.
Velocity is speed with a direction
three facts about speed and velocity
It is the speed or velocity at a particular instant.
Velocity is speed and direction
Velocity is speed with direction
