Is pounds scalar or vector?
Weight is a force, so it is a vector. It would be hard to make sense of this diagram if you were considering weight to be a scalar. Thorsten S. In special relativity, some people define energy and momentum as the time and space components of the 4-momentum, respectively.
What is the vector of weight?
force
Weight is a force which is a vector and has a magnitude and direction. Mass is a scalar. Weight and mass are related to one another, but they are not the same quantity.
What is the SI unit for pounds?

What are the units of a vector?
A unit vector is a vector whose magnitude is 1, or in mathematical terms, a unit. In vector geometry, the notation of a unit vector is slightly different. Unit vectors are denoted by placing a hat (^) on top of the vectors. The vector v shown in the figure below is a unit vector and can be represented by v^.
How do you write weight as a vector?
Weight is the force acting on an object by gravity. F(gravity) = mg where, on earth, g=-9.8 This is a vector in the ‘down’ direction.
How are scalars and vectors the same?
Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.
How is weight a vector quantity example?
It can be expressed as w=mg, where m is mass of the object and g is the acceleration due to gravity. So, we can define weight as a force with direction towards the centre of the planet. weight has both the magnitude and direction. Hence, weight is a vector quantity.

Do unit vector has unit?
What is the magnitude of a unit vector? The magnitude of a unit vector is unity. Unit vector has only direction and no units or dimensions.
What is the definition of a unit vector?
In the definition of unit vector, “A unit vector is every vector whose magnitude is 1 unit,” the word does not really refer to units like meter and second. It rather means just ‘1’ and could be skipped. A true unit vector has no physical dimension (like force) but only a direction.
What is the magnitude of a unit vector?
A vector is a quantity that has both magnitude, as well as direction. A vector that has a magnitude of 1 is a unit vector. It is also known as Direction Vector.
Is weight a vector?
My thought process is that since weight is a force, and since force is a vector, weight has to be a vector. This is the basic transitive property of equality. Am I and all of these other sources wrong about weight being a vector? Is weight sometimes a vector and sometimes a scalar?
How do you find the unit vector with the same direction?
To find a unit vector with the same direction as a given vector, we divide the vector by its magnitude. For example, consider a vector v = (1, 4) which has a magnitude of |v|.
