If by "triple dot product" you mean u·v·w, then no, because that would imply the existence of a dot product between a vector and a scalar.

Why dot product of two vectors is scalar?

That's the way it is defined.


The triple product of 6a and b2?

The "triple product" is defined for vectors. You can't calculate a triple product if you don't know the components of the vectors (or some other information, that allows you to calculate those).


When you use cross product and dot product in vector?

Dot product and cross product are used in many cases in physics. Here are some examples:Work is sometimes defined as force times distance. However, if the force is not applied in the direction of the movement, the dot product should be used. Note that here - as well as in other cases where the dot product is used - the product is greatest when the angle is zero; also, the result is a scalar, not a vector.The cross product is used to define torque (distance from the axis of rotation, times force). In this case, the product is greatest when the two vectors are at right angles. Also - as in any cross product - the result is also a vector.Several interactions between electricity and magnetism are defined as cross products.


What is defined as force times distance?

Work is defined as the dot product of force times distance, or W = F * d = Fd cos (theta) where theta is the angle in between the force and distance vectors (if you are doing two dimensions). In three dimensions, use the standard definition for the dot product (using the component form of the vectors).


What is vector dot product?

The dot-product of two vectors is the product of their magnitudes multiplied by the cosine of the angle between them. The dot-product is a scalar quantity.

here are the possible answers: A) A tridimensional vector B) A 4D vector C) A 5D vector D) An scalar number E) It is undefined


What are the applications of cross product and dot product in physics?

cross: torque dot: work


Is there any direction associated with the dot product of two vectors?

No. The dot product is also called the scalar product and therein lies the clue.


Why in dot product you use cos and in vector product sin?

We use the dot product cos and in vector we use the vector product sin because of the trigonometric triangle.


What is the angle in which the dot product of two non zero vectors is equal?

It depends on what the dot product is meant to be equal to.


What are the properties of a dot product?

In mathematics, the dot product is an algebraic operation that takes two equal-length sequences of numbers (usually vectors) and returns a single number obtained by multiplying corresponding entries and adding up those products. The name is derived from the interpunct "●" that is often used to designate this operation; the alternative name scalar product emphasizes the scalar result, rather than a vector result.The principal use of this product is the inner product in a Euclidean vector space: when two vectors are expressed in an Orthonormal basis, the dot product of their coordinate vectors gives their inner product. For this geometric interpretation, scalars must be taken to be Real. The dot product can be defined in a more general field, for instance the complex number field, but many properties would be different. In three dimensional space, the dot product contrasts with the cross product, which produces a vector as result.


Dot product is?

Dot product is an algebraic operation when two equal-length sequences of numbers are returned as a single number.
