1.
What is the difference between a scalar quantity and a vector quantity?
A scalar is fixed by direction and magnitude, such as force; a vector is fixed by magnitude alone, such as mass
Both are fixed by magnitude alone; they differ only in units
A scalar is fixed by magnitude alone, such as mass; a vector is fixed by magnitude and direction, such as force
A scalar is fixed by magnitude and direction, such as speed; a vector is fixed by magnitude alone, such as time
