A vector is any physical quantity that can be described using the magnitude and direction. There are two main type of quantities that you must keep in mind. Scalars and vectors.

A scalar is a physical quantity that needs only magnitude to be described. For example, electric charge. You don’t need to define any direction of electric charge. Just the magnitude.Similarly, Temperature, mass etc. Like it is meaningless to ask “ 300 K in what direction?” Or the mass of an object is 30 Kg towards east. This statement is vague.

Coming to vectors, popular example is velocity. The scalar counterpart of velocity is speed. When you say that the car is travelling at 60 km/hr, you are actually mentioning the speed of the car. But when you say that the car is travelling at 60 km/hr towards east, that’s the velocity because you just added the direction to the magnitude to give a complete information.
