### 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.

### Do vectors have quantity?

Both scalars and vectors have quantity. The difference is a vector has quantity and direction, whereas scalars only have quantity.

There is no difference between vector addition and algebraic addition. Algebraic Addition applies to vectors and scalars: [a ,A ] + [b, B] = [a+b, A + B]. Algebraic addition handles the scalars a and b the same as the Vectors A and B

### Is it possible the add a vector and scalar?

no!!!only scalars and scalars and only vectors and vectors can be added.

### 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.

### 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.

### 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.

### 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.

no

### How are scalars and vectors simi?

They both have magnitude.

### What are the two kinds of measure?

vectors and scalars.....
