Velocity is a vector. The magnitude of the velocity - its absolute value - is its speed.

0This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.

It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)

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.

It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."

No, you've got it backwards. The absolute value of velocity equals speed. Velocity is speed with a direction; speed is just a number, without regard to direction.

Yes. Speed is a scalar, while velocity is a vector.

Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.

For the instantaneous value of average velocity, average speed and average velocity are equal.

Decelerating means that the speed, i.e., the absolute value of the velocity, decreases over time.

Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.

If s is the displacement vector of an object at time t, thenvelocity = ds/dt, the derivative of s with respect to tand speed = |ds/dt|, the absolute value of the velocity.

Velocity is a vector which incorporates both speed (a scalar) and direction. So the speed (distance divided by time) must increase if the velocity increases as the direction (an angular measurement) does not affect the absolute value of the vector.

mph or 'miles per hour' is a unit and can equal any value of speed or velocity.

An absolute value can not be negative.

The distance will increase as the speed (absolute value of velocity) increases.

Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.

If a number is zero or positive, then its absolute value is equal to the number.

Speed is an example of a rate of change. It is specifically the rate of change of distance over time.In calculus, speed is the absolute value of velocity. Velocity measures both speed and direction, while speed only measures speed. For example, if a car is driving backward with a speed of 90km/h, its velocity would be -90km/h because "backward" indicates a "negative" velocity.

KE=(1/2)(m)(v2) since speed is absolute value of velocity, but velocity is squared, (speed)2=(velocity)2 then doubling the speed with no change in mass will change the KE by a factor of; 22=4

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 msâˆ’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.)

No, the absolute value of a number cannot equal a negative number.

The magnitude(the value). Speed is only magnitude Velocity is magnitude & direction

Because velocity has a direction but speed does not. A vector has both a numerical value and a direction but a speed has only a numerical value and therefore it can't be represented by a vector.

I believe that would be constant velocity. Note: be careful when talking about "speed" as opposed to velocity, as they are two different concepts in physics. Speed has no direction and is therefore always positive. Velocity on the other hand has a specific direction associated with it and can therefore be positive or negative. It is therefore said that speed is the magnitude or the absolute value of velocity. Be careful in the future.

A measurement that has magnitude and direction. The magnitude is equal to the absolute value of the vector measurement. For example, Velocity is a vector measurement. A velocity of -20 miles per 1 second would suggest moving away from the origin point in a two-dimensional measurement at a rate of 20 miles per 1 second. The absolute value of this would be 20 miles per 1 second, which would also be the speed. Therefore, speed is the magnitude of Velocity. Subsequently, any measurement that has a magnitude, but no direction, is not a Vector measurement, but rather a scalar measurement. Some examples of vector measurements would be Displacement, Velocity, and Acceleration.
