Yes, a physical quantity can have magnitude and direction but still be a scalar if it doesn't obey the vector addition. An example is Electric Current which has magnitude and a fixed direction, but it does not follow vector laws of addition.
Matter is anything that possesses mass, occupies space and may be perceived through one or more senses.
The physical divisions of matter are:
1. Solid : Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
2. Liquid : Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can...
Any vector directed in two dimensions can be thought of as having two different components. The component of a single vector describes the influence of that vector in a given direction.
