Magnitude can only be a real number - that is 0 to infinity. A negative magnitude would imply a direction, which is what a vector is about: magnitude and direction.
It's like temperature, in actuality there is no negative, only 0 and up (the Kelvin scale demonstrates this better than Fahrenheit or Celsius as they are meant to be relative, not absolute scales. The Kelvin scale says absolute 0 = no molecular movement at all. You can't have negative molecular movement {either it's moving or it's not}, the Kelvin scale is a good example as a scalar, it can be 0 or higher, no negatives.
What else can I help you with?
Define the terms scalar and vector?
scalar has only a magnitude vector has both magnitude and direction
Scalar and vector?
A scalar is a magnitude that doesn't specify a direction. A vector is a magnitude where the direction is important and is specified.
What kind of quantity is the magnitude of a vector quantity?
The magnitude of a vector is a scalar.
Is the magnitude of a vector quantity a dimensionless number?
Yes, the magnitude of a vector is a scalar.
Can a vector be added to a scalar?
No- vector ad scalar are two different things. Scalar consists only of magnitude, whereas vector consists both magnitude and direction.
What are scalar and vector forces?
There is no such thing as scalar and vector forces. However, there are scalar and vector QUANTITIES, and force is a vector quantity, as all forces have direction and magnitude. Scalar quantities, on the other hand, have only magnitude and no direction.
A vector quantity has direction a scalar quantity does not true or false?
True. A vector quantity has both magnitude and direction, while a scalar quantity only has magnitude.
A vector is a quantity with magnitude and ___?
A vector is described by magnitude and direction (a scalar has only magnitude).
Can a scalar quantity be the product of 2 vector quantities?
No, a scalar quantity cannot be the product of two vector quantities. Scalar quantities have only magnitude, while vector quantities have both magnitude and direction. When two vectors are multiplied, the result is a vector, not a scalar.
How does a vector quantity differ from a scalar quantity?
A scalar quantity defines only magnitude, while a vector quantity defines both a magnitude and direction.
The main difference between a scalar and a vector quantity is?
A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.
Is a vector quantity is always the same as a scalar quantity?
No, a vector quantity and a scalar quantity are different. A vector has both magnitude and direction, while a scalar has only magnitude. Velocity and force are examples of vector quantities, while speed and temperature are examples of scalar quantities.
