Is it possible to multiply a vector quantity to a scalar quantity?
The product of scalar and vector quantity is scalar.
Why gradient of scalar field is vector?
The Law of Numbers?There are two kinds of numbers scalars and vectors. The law of multiplication of Numbers says, the product of a scalar and a vector is a vector.In 4D derivative is X = [d/dr, GRAD] = [d/dr, Id/dx + Jd/dy + kd/dz]GRAD is a vector.The 4D derivative of a number [b,B], where b is the scalar and B is the vector, is;X[b, B] = [d/dr, GRAD] [b.B] = [db/dr - GRAD.B, dB/dr + GRAD b + GRADxB]The general rules of numbers are:1.Scalar by scalar products are scalars e.g. db/dr2. Scalar by vectors and vector by scalars are vectors, e,g, dB/dr and GRAD b3. Vector Dot (.) Products are scalars ,e.g. GRAD.B4. Vector Cross (x) Products are vectors, e.g. GRADxB.
What is the difference between scalars and vectors using displacement and distance?
A scalar is a real quantity like distance and a vector is a vector quantity like displacement.Displacement is the product of a distance and a direction,Displacement =DistancexDirection.
Do vectors have a direction?
Yes, vectors must have the direction. Without direction, it is simply a scalar quantity.
What is the difference between scalar and vector drives?
a vector drive is vertical, a scalar is horizontal.
Why is scalar product two vectors a scalar?
Scalar product of two vectors is a scalar as it involves only the magnitude of the two vectors multiplied by the cosine of the angle between the vectors.
What is the difference between a scalar quantity and a vector?
Scalars are quantities that have magnitude only; they are independent of direction. Vectors have both magnitude and direction. vectors need bold letters to show them.
Is it possible to multiply a vector quantity to a scalar quantity?
The product of scalar and vector quantity is scalar.
Can the sum of two vectors be a scalar?
No.
What is the difference between coplanar vectors and collinear vectors?
The term collinear is used to describe vectors which are scalar multiples of one another (they are parallel; can have different magnitudes in the same or opposite direction). The term coplanar is used to describe vectors in at least 3-space. Coplanar vectors are three or more vectors that lie in the same plane (any 2-D flat surface).
What is the product of vector and scalar?
The scalar product of two perpendicular vectors is zero.In classical mechanics we define the scalar product between two vector a and b as:a · b = |a| |b| cos(alpha)where |a| is the modulus of vector a and alpha is the angle between vectors a and b.If two vectors are perpendicular, alpha equals 90º (or PI/2 rad) and cosine of alpha is, consequently, zero.So finally a · b = 0.

What is the difference between scalene and scalar triangles?
there is no difference
Explain the difference between scalars and vectors?
A scalar is simply a real number (sometimes complex numbers are used). A vector has both a magnitude (a number), and a direction. Examples: Mass is a scalar; a force is a vector (you may get different results if you pull in different directions).
What is the value of scalar product of two vectors A and B where value of vector A and B is not zero and vector product of two vectors A and B is not zero?
Scalar product = (magnitude of 'A') times (magnitude of 'B') times (cosine of the angle between 'A' and 'B')
Is it scalar or vector when a car stops at a stop sign?
It is neither a scalar or a vector? Scalar and vectors are used to describe quantities, for example scalars include distance and mass, while vectors include weight and velocity. We do not say that a situation is a scalar or a vector.
What is the difference between scalars and vectors using displacement and distance?
A scalar is a real quantity like distance and a vector is a vector quantity like displacement.Displacement is the product of a distance and a direction,Displacement =DistancexDirection.
