Scalar quantity is the usual one. It is already there unavoidable. But vector is the new one. Why do we need it?
Suppose say two persons by name John and Johann push a box with forces 4N and 3N, what could be the effective force on the box?
One may say 7 N by adding them. One may say just 1N because of getting the difference. Another may say 5N. How?
Why do they give different answers?
It is because the directions in which the forces acting are considered in different ways.
If both in the same, addition is ok. If in opposite then difference is right one. If they are at right angles then pythagros technique. So direction is the most essential data to get the right answer.
Hence magnitude with direction is known to be vector quantity.

What is the difference between scalar and vector products of two vectors?
The scalar product (dot product) of two vectors results in a scalar quantity, representing the magnitude of the projection of one vector onto the other. The vector product (cross product) of two vectors results in a vector quantity that is perpendicular to the plane formed by the two input vectors, with a magnitude equal to the area of the parallelogram they span.
What word indicates the difference between vector and scalar measurements?
Direction. A scalar has only magnitude, while a vector has both magnitude and direction.
Can a scalar product be a negative quantity?
Yes, a scalar product can be negative if the angle between the two vectors is obtuse (greater than 90 degrees). The scalar product is the dot product of two vectors and is equal to the product of their magnitudes and the cosine of the angle between them. A negative scalar product indicates that the vectors are pointing in opposite directions.
Can a scalar product by a negative quantity?
Yes, a scalar product can be negative if the angle between the two vectors is greater than 90 degrees. In this case, the dot product of the two vectors will be negative.

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.

Can the sum of two vectors be a scalar?
No.
Can scalar product be negative?
Yes, the scalar product of two vectors can be negative if the angle between them is obtuse (greater than 90 degrees). In this case, the result of the scalar product will be negative.
What is the difference between scalene and scalar triangles?
there is no difference
What is scalar and vector product simplify?
Scalar product (or dot product) is the product of the magnitudes of two vectors and the cosine of the angle between them. It results in a scalar quantity. Vector product (or cross product) is the product of the magnitudes of two vectors and the sine of the angle between them, which results in a vector perpendicular to the plane containing the two original vectors.
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).
