# Do speed and velocity have same meaning?

###### Answered 2016-02-23 15:35:36

No. It's confusing unless you're into physics or mathematics but velocity is a vector quantity with speed is one aspect. Velocity includes speed and the direction of motion. A car is going 60 miles per hour as speed. A car is going 60 MPH due north is velocity.

In popular speech it is the same; in physics, it is not. Velocity is a vector, meaning that it includes a direction. Speed is just the number, that is, without specifying a direction.

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

No. Speed is the magnitude of the velocity vector. If velocities are the same, their magnitudes are the same, which is another way of saying that the speeds are the same.It can work the other way around, however ... same speed but different velocities, meaning same speed in different directions.

all wheels generate same velocity meaning all drive at same speed

No, they are not the same! Velocity involves the speed and the direction of the moving object...

same speed , coz velocity is constant velocity consists of speed and direction...

No. Speed has no direction. Velocity is speed anddirection.

velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.

One example of Velocity is that if you are running in the same direction, your speed and velocity is the same. But if you are running AROUND the track, your speed is the same but your velocity is changing.

Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.

Speed doesn't "become" velocity. Velocity is simply speed as a vector, meaning that not only the magnitude is specified (as in the speed), but also the direction.

No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.

Except for the fact that velocity has a direction, velocity and speed have the same units; so you would have a speed squared (plus a direction). As far as I know, this has no physical significance - meaning that you won't normally carry out this multiplication.

acceleration is change in velocity over time. It is important to know that speed is not a vector quantity; it is scalar (meaning it does not have direction), -- velocity does. Therefore, speed is only the MAGNITUDE of velocity. Also, acceleration is a vector quantity meaning it has both magnitude and direction. If you change EITHER magnitude or DIRECTION, acceleration changes. Okay anyway to answer your question, You can have the same magnitude of velocity (aka same speed) and still be accelerating if YOU CHANGE DIRECTION. --- gh

Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.

In common speech, velocity means speed, they are the same thing.

No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.

No. Speed tells the size of velocity, but velocityalso includes the direction of the motion.

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.

Velocity is speed, plus an indication of direction. To indicate a velocity, you can indicate a speed (this will logically use units of speed), and a direction.

Speed and velocity are never the same thing.Velocity means 'speed' AND the direction it's going.

The size of velocity and the size of speed are the same number. But velocity also has a direction and speed doesn't.

The root word for velocity is veloc. Meaning...I do believe..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.
