Velocity is a vector quantity and so has an associated direction.

Speed is a scalar quantity and hence does not.
Velocity is a vector and speed is a scalar Velocity is different because it also includes it's magnitude and direction. If positive is left and negative is right. Say a car is going in the positive direction then decides to stop and back up at the same speed it was going before. When it is backing up, it will be going in a negative direction. However, if it was speed, it's speed wouldn't change. Speed does not measure the magntidude or direction.
Velocity is speed with direction . The formula of velocity is :

v= delta "r" / t [ velocity = movement / time ]

Speed is a movement without direction .The formula of speed is :

v= S / t

Imagine a car moving forward for 50meters and then moving backwards for 20 meters .

The movement in velocity (delta r) --> 50-20= 30m

The "s" in Speed ---> 50+20= 70m

so in velocity you gotta take into consideration , whether the car moves forward or backwards . As far as speed is concerned , the only thing you need to do is summing up all the distance that the car's made .

How the velocity of an escalator that is going up different from the velocity of one that is going down at the same speed?

Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.


The speed of an object and the direction of its motion?

the object's 'velocity'


What is the main difference between speed and velocity involves?

Velocity includes the information on what direction the speed is pointing. 60 mph north and 50 mph north are different velocities. 60 mph north and 60 mph west are also different velocities. Speed doesn't care what direction it's going. 60 mph north and 60 mph west are the same speed. 60 mph 50 mph are different speeds.


What is an example of the difference between speed and velocity?

Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.


The speed and direction of a moving object is called?

velocityYou mean, Velocity.. Velocity is the rate of change of displacement (position). It is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is speed, a quantity that is measured in meters per second (m/s or ms−1) when using the SI (metric) system.I linked my source.Speed in a specific direction is called velocity.speed is a scalar unit whereas velocity is a vector unit.Speed is the rate of change of position. In vector terms, speed is the magnitude of the velocity. (Velocity is speed and direction; speed is the velocity along a given direction.)

Are speed and velocity different?

SPEED has the speed only; while VELOCITY has the direction and the speed.


How is velocity different from average speeed?

Velocity is speed and its direction. Average velocity is average speed and its direction.


Is velocity speed?

As used in physics, the two are different. Speed is a scalar, velocity a vector.


How is speed of a body related its velocity?

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.


What the different between velocity and 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!)


Does a speedmeter give instantaneous speed or velocity?

Velocity is a vector quantity, so a different direction makes a different velocity. Speed is a scalar quantity, where direction makes no difference. Since a speedometer reads the same regardless of direction of motion, it is providing speed, not velocity.


Can speed change the velocity of an object?

Speed is measured in m/s. Velocity is measured in m/s IN A SPECIFIC DIRECTION. You may be driving at 4 mph north, or at 5 mph at 330˚, and your velocity in the northern direction will still be 4 mph. In this example, your speed is different, but your velocity is the same. Thus even if speed remains constant, but its direction changes, your velocity will be different.


Can the speed of a body change if its velocity is changed?

Simly stated, velocity is speed in a defined direction. If you travel 5mph north, the speed is the same as if you travel 5mph east, but the velocity is different.


Are they the same or they different the speed and velocity?

Speed and velocity are related but different. Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction of motion. Therefore, velocity gives information about the speed and the direction of motion.


How is velocity and speed different?

Velocity has a direction.

What is speed and how is speed different from velocity?

Velocity is speed plus direction. If you say you are traveling at 54 miles per hour, you are giving your speed. If you say you are going north at 54 miles per hour, you are giving your velocity.
