a magnitude - the quantity representing how fast an object is moving

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

That is the speed or velocity.That is the speed or velocity.That is the speed or velocity.That is the speed or velocity.

In common language, the terms "velocity" and "speed" are used interchangeably. In physics, "velocity" is a vector, and "speed" is not - meaning that when the word "velocity" is used, it specifies not just how fast something moves, but also in what direction.

speed is how fast an element moves .velocity includes the speed of an object and direction of its motion

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.

In common language, the terms are used interchangeably. But in physics, speed is a scalar; velocity is a vector. That is, a speed is just a number (and a unit) - for example, 50 kilometers/hour. But when it is important to distinguish a direction, you talk about a velocity. For example, "50 kilometer/hour to the north". Velocity is a speed AND a direction. "50 km/hour north" and "50 km/hour east" are the same speed but different velocity.

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

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.

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

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.

In common usage Velocity and Speed are used interchangeably. However, velocity has a specific meaning in the scientific sense.speed is the rate at which you are moving.velocity is the rate at which you are moving in a specific direction.So if two space ships are heading away from the sun in different directions, but with the same speed, these spaceships are said to have a different velocity.Related to velocity is acceleration. Again in common usage it is how fast you are speeding up or slowing down. In science it has a similar meaning but it is the rate of change of velocity.In other words, you can experience acceleration simply by changing you direction of travel, even if you keep the speed constant.

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 with direction
