* A scalar is just a number, used to represent the magnitude of something. thus, 35 is a scalar number that can mean that something is 35 inches long, 35 meters high, 35 years old, or etc. * A vector is a magnitude that has a direction. usually this is represented by magnitudes on axes that are perpendicular to each other. so, the vector ( 5 7 ) (usually written with the 5 over the 7, but the software here won't handle that) means the line from (0,0) to (5,7). notice that this line has both a magnitude (length) and a direction: i.e., it points in a different direction than the vector ( 7 5 ) but has the same magnitude, and points in the same direction as the vector ( 10 14 ) but has a different magnitude. * A tensor is a vector that has a position in space. vectors (by definition) all begin at the origin (0,0); tensors are constructed the same way but can have their origin anywhere.

∙ 13y agoScalars have magnitude only. They are specified by a number with a unit and obey the rules of arithmetic and ordinary algebra.
Vectors have both magnitude and direction and obey the special rules of vector algebra.

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.
How are scalar and vector quantaties alike?
Scalars and vectors quantities can represent the same measure e.g.Energy = -mu/r + mc, ; -mu/r is scalar energy and mcV is vector energy.
What is it called when a scalar and a vector are multiplied together?
When a scalar quantity(if it has positive magnitude) is multiplies by a vector quantity the product is another vector quantity with the magnitude as the product of two vectors and the direction and dimensions same as the multiplied vector quantity e.g. MOMENTUM
What are the two types of measurements?
Vectors and Scolars Vectors: have an magnitude and a direction Scolars: have an magnitude but have no direction
Explain what is meant by a concurrent vectors?
A vector has 2 components - it's magnitude and direction. Concurrent vectors are 2 vectors that have the same direction but may have different magnitudes.
What are difference between scalars and vectors?
What are difference between scalars and vectors
One difference between vectors and scalars?
Vectors have a direction associated with them, scalars do not.
Is it possible the add a vector and scalar?
no!!!only scalars and scalars and only vectors and vectors can be added.
Are vectors and scalars the same?
No, scalars and vectors are not the same. Scalars are measurements in numbers. Examples: work, energy, mass, speed, and distance. Scalars measure in one magnitude. Vectors measure velocity, acceleration, force, and momentum.
Why is the difference between scalars and vectors important?
Without the difference between scalars and vectors the Universe doesn't work !
Can Vectors be added together scalar quantities cannot?
Vectors can be added to other vectors in the same vector space. Scalars can be added to other scalars if they have the same units. Scalars cannot be added to vectors, nor vice versa, directly.
Do vectors have quantity?
Both scalars and vectors have quantity. The difference is a vector has quantity and direction, whereas scalars only have quantity.
Why can't we add or subtract vectors like scalars?
Because scalars do not take in the direction but just the magnitude while vectors can. You can add vectors ONLY if they are in the same direction.
Are the rules of adding vectors and scalars the same?
no
How are scalars and vectors simi?
They both have magnitude.
What are the two kinds of measure?
vectors and scalars.....
What are two kind of measurement?
vectors and scalars.....
