what are the difference between a vector and scalar quantity?

A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.

Area is a scalar quantity. A circle for example has an area of . Area is also a measure.

The dot product of two vectors is a scalar because it was the part of the quaternion product that was a scalar. The cross product of two 3-vectors is a vector because it was the part of the quaternion product that was a vector.

Average velocity is a vector quantity, meaning it includes the magnitude and the direction of the object. While average speed is a scalar quantity which only has the magnitude of the object. ... The unit of measurement of velocity is the same as that of speed, but its a derived unit.

Scalar quantities have only magnitude; vector quantities have both magnitude and direction. ... It has only magnitude, no direction. Force, displacement, and acceleration all occur with a designated direction.

Scalars, Vectors and Matrices A scalar is a number, like 3, -5, 0.368, etc, A vector is a list of numbers (can be in a row or column), A matrix is an array of numbers (one or more rows, one or more columns).

Acceleration is a vector quantity because it has both magnitude and direction. When an object has a positive acceleration, the acceleration occurs in the same direction as the movement of the object.

In mathematics, the dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors) and returns a single number. ... These definitions are equivalent when using Cartesian coordinates.

Very simple, a vector quantity is a quantity that has both magnitude and direction. Now, a null vector has a magnitude equal to zero(0) and as it is just a point graphically, so it can be assigned any arbitrary direction. Thus a null vector has both magnitude and direction. So, it's a vector, indeed.

Scalar quantities are defined by a magnitude with no applicable direction. In contrast, vector quantities must have both magnitude and direction of action. Some common scalar quantities are distance, speed, mass, and time. Some common vector quantities are force, velocity, displacement, and acceleration.

Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.

A scalar quantity is a one dimensional measurement of a quantity, like temperature, or mass. A vector has more than one number associated with it. A simple example is velocity. It has a magnitude, called speed, as well as a direction, like North or Southwest or 10 degrees west of North.

vector function has both quantities magnitude and direction whereas scalar has only one quantity which is magnitude. ... scalars have magnitude but no direction.

No, force is a vector quantity, it is defined by its magnitude and direction. Common vector quantities are displacement, velocity, acceleration and force. Common scalar quantities are distance, speed, work and energy.

Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.

Distance is a scalar quantity . it can never be 0 when the body is in motion. displacement is a vector quantity . ... A distance is the length of actual path travelled by a body.

Vector quantities have two characteristics, a magnitude and a direction. Scalar quantities have only a magnitude. When comparing two vector quantities of the same type, you have to compare both the magnitude and the direction.
