# What is the difference between scalar and vector product?

The main difference between scalar and vector quantity is that the scalar quantity is the one that is simply related to the magnitude of any quantity. The vector quantity is determined by both the magnitude as well as the direction of the physical quantity.

What is the difference between vector product and scalar product?

A scalar quantity has only magnitude, but no direction. Vector quantity has both magnitude and direction. … For example, the dot product of two vectors gives only scalar, while, cross product, summation, or subtraction between two vectors results in a vector.

What is difference between scalar and vector?

What is the relation between scalar and vector product?

We use both of these operations on the vectors. The dot product of two vectors gives us a scalar quantity and the cross product of two vectors gives us a vector quantity. Since the dot product produces a scalar quantity from the vectors, it is also called the scalar product.

## What is vector product with example?

The unit vectors i, j and k. Note that k is a unit vector perpendicular to i and j. This is the formula which we can use to calculate a vector product when we are given the cartesian components of the two vectors. Example Suppose we wish to find the vector product of the two vectors a = 4i+3j+7k and b = 2i+5j+4k.

## What is a scalar product?

Definition of scalar product

: a real number that is the product of the lengths of two vectors and the cosine of the angle between them. — called also dot product, inner product.

## What is the difference between vector and scalar quantity give examples of both?

A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it. Example: Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude.

## What is vector product of two vectors and explain any two characteristics?

The vector or cross product of two vectors is a vector whose magnitude is equal to the product of the magnitudes of the two vectors and the sine of the angle between the two vectors. Characteristics of the Vector product: Vector product two vectors is always a vector.

## What is the scalar triple product?

Scalar triple product is the dot product of a vector with the cross product of two other vectors, i.e., if a, b, c are three vectors, then their scalar triple product is a · (b × c). It is also commonly known as the triple scalar product, box product, and mixed product.

## What are the two products of vector?

A vector has both magnitude and direction and based on this the two product of vectors are, the dot product of two vectors and the cross product of two vectors. The dot product of two vectors is also referred to as scalar product, as the resultant value is a scalar quantity.

## What is scalar product class 11?

Scalar product. Scalar product. The scalar product or dot product of any two vectors A and B, denoted as A.B (Read A dot B) is defined as , where q is the angle between the two vectors. A, B and cos θ are scalars, the dot product of A and B is a scalar quantity.

## What does vector product of two vectors mean?

Answer: The vector product of two vectors refers to a vector that is perpendicular to both of them. One can obtain its magnitude by multiplying their magnitudes by the sine of the angle that exists between them.

## What do you mean by vector quantity?

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.

## What is scalar product explain characteristics of scalar product?

The scalar product of two vectors is defined by multiplying their magnitudes with the cosine of the angle between them. The scalar product of orthogonal vectors vanishes and the antiparallel vectors are negative. Characteristics of Scalar product of two vectors: The scalar product is commutative.

## What are the characteristics of scalar product?

• Scalar product is commutative.
• Scalar product of two mutually perpendicular vectors is zero.
• Scalar product of two parallel. vectors is equal to the product of their magnitudes.
• Self product of a vector is equal to square of its magnitude.

## What are the properties of scalar product?

Properties of the scalar product

• The scalar product of a vector and itself is a positive real number: u → ⋅ u → ⩾ 0 . …
• The scalar product is commutative: u → ⋅ v → = v → ⋅ u → . …
• The scalar product is pseudoassociative: α ( u → ⋅ v → ) = ( α u → ) ⋅ v → = u → ⋅ ( α v → ) where is a real number.

## How do you cross product a vector?

The Vector Cross Product – YouTube

## What do you mean by vector product also discuss about their properties?

: a vector c whose length is the product of the lengths of two vectors a and b and the sine of their included angle, whose direction is perpendicular to their plane, and whose direction is that in which a right-handed screw rotated from a toward b along axis c would move.

## Are dot product and cross product the same?

The dot product is a product of the magnitude of the vectors and the cosine of the angle between them. The cross product is a product of the magnitude of the vectors and the sine of the angle between them.

## What is the vector formula?

The vector equation of a line between two points a and b was found in Chapter 9 to be r = a(l – t)+ b t where t is some parameter and for points between A and B then 0≤t ≤ 1.

## What is the relationship between A and B if a B 0?

8. the relationship between a and b if a + b = 0 2 × 8 = 16 … SOLUTION: If a + b =0, then a and b are additive inverses.

## What is the dot product of i and j?

In words, the dot product of i, j or k with itself is always 1, and the dot products of i, j and k with each other are always 0.

## Can you multiply 3 vectors?

The scalar triple product of three vectors a, b, and c is (a×b)⋅c. It is a scalar product because, just like the dot product, it evaluates to a single number. (In this way, it is unlike the cross product, which is a vector.)

## What is ABC vector?

## What is the dot product of two same vectors?

The dot product of two vectors is equal to the product of the magnitude of the two vectors and the cosecant of the angle between the two vectors. And all the individual components of magnitude and angle are scalar quantities. Hence a.b = b.a, and the dot product of vectors follows the commutative property.
