what is the meaning of vectors and scalar???

Question

anonymous · Answer

Vector quantities always include a magnitude with direction

In contrast, Scalar quantities only denote a value.

Think of it like this:
Vector:  I am driving 60 Mph in a NW direction
Scalar:  I am driving at a speed of 60 Mph.

Vector: I have walked 20 meters to the SW
Scalar:  I have walked 20 meters from where I started.

anonymous · Answer

vector is showing direction and magnitude...scalar just shows magnitude...

anonymous · Answer

Scalars are typically the magnitude, however such quantities can be a coefficient for another term as well.  

Example: 2x+6y=2(x+3y), where the 2 is a portion of the magnitude(scalar quantity) of this equation

anonymous · Answer

simple examples of vectors are: velocity, acceleration, force

scalars: pressure, temperature, speed, energy
