Yes, a scalar can be a negative number. For instance:
c<x₁,x₂> = <cx₁,cx₂> such that <x₁,x₂> is a vector.
Let c = -1 for instance. Then, we have this vector:
<-x₁,-x₂>
Compared to <x₁,x₂>, <-x₁,-x₂> has negative signs.
In physics and mathematics, if we multiply the vector or something by a negative value scalar, then the direction of the vector is reversed, and the magnitude stays the same. If the magnitude increases/decreases, and the direction of the vector is reversed, then we can multiply the vector by any negative non-1 scalar value.
A matrix and a scalar is a matrix. S + M1 = M2. A scalar is a real number whose square is positive. A matrix is an array of numbers, some of which are scalars and others are vectors, square of the number is negative. A matrix can be a quaternion, the sum of a scalars and three vectors.
No, Speed is always greater than or equal to zero. However, velocity can be negative, which just means you have a positive speed in the opposite direction! (scalar(number) versus vector).
-234 is greater.. Because in the number line if we go in negative side then the higher the scalar value lower the vector value.
In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number, or a physical quantity.
Yes.
Noo! because it is a number and distance that is a scalar quantity so it can not be negative and it have no direction also
radius is a scalar quantity, it can not have a negative value.
No,because scalar quantities have no direction. So they cant be negative
A scalar quantity may have positive and negative values - it is simply a real number. But it doesn't have a direction. Think of it as a "vector in one dimension" - whereas the usual vectors have at least 2 dimensions.

A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.
scalar lol
A vector has a direction associated with it. A number (or scalar) does not.
Scalars can be negative, and so can a change in a scalar value.Take temperature:You can have a temperature of -10 degrees.If temperature falls from 20 to 5 degress, the change was -15 degree.The negative value of the scalar is a consequence of where you take the "zero" to be.With speed you have to be very careful because speed is the scalar bit of velocity. Velocity with no consideration of direction.
There is no direction in number of moles, so it is scalar.
scalar
Scalar is a type of quantity which contains magnitude only and has no direction. For example: distance and speed
