Vector quantities are quantities that have both magnitude and direction. An easily understood example is velocity, which has both speed (the magnitude component) and direction. If we say 60 miles per hour or 8 knots per hour, and we add direction, like east or west, or course 220 magnetic, for example, we're talking about a vector. Electromagnetic fields also have amplitude (a measure of magnitude) like 10 volts/m and direction east or north for example. It really is that simple, and the investigator only has to remember the direction component and add it to a magnitude to lock in the idea.
Light is not a vector quantity, it has size and the speed of light 300 mega meters/second, but it does not have a direction. Another example is like saying I was driving home at 60 mph. The '60 mph' is a speed, but not a velocity (a vector) because there is no direction specified.
It is important in science to distinguish between vectors and real quantities. Real quantities do not have a direction. This can be seen as no direction or it can be seen as omnidirectional. Omnidirectional would be wrong, at best reals could be said to be origin directional. Positive real could be said to be toward the origin and negative real could be said to be away from the origin. Vectors are related to the origin and directional axis. Real numbers define the origin and a real axis, vector quantities define specifically directions and directional axis based on the real zero point.

Can we have physical quantities which have magnitude and direction but are not vectors if yes how?
yes we can have. for eg electric current, pressure etc though these quantities have both magnitude and direction their directions are not necessary to define them and vectors are those quantities which has magnitude and requires direction to be defined " quantities having both magnitude and direction is a vector" is not a corrrect definition ofa vector
Is it scalar or vector when a car stops at a stop sign?
It is neither a scalar or a vector? Scalar and vectors are used to describe quantities, for example scalars include distance and mass, while vectors include weight and velocity. We do not say that a situation is a scalar or a vector.
How are scalar and vector quantaties alike?
Scalars and vectors quantities can represent the same measure e.g.Energy = -mu/r + mc, ; -mu/r is scalar energy and mcV is vector energy.
What are the two types of measurements?
Vectors and Scolars Vectors: have an magnitude and a direction Scolars: have an magnitude but have no direction
Explain what is meant by a concurrent vectors?
A vector has 2 components - it's magnitude and direction. Concurrent vectors are 2 vectors that have the same direction but may have different magnitudes.
What are the 2 quantities of physics?
Scalars and Vectors quantities
What are the vectors?
Vectors are quantities that have both value and direction. Such as displacement and Velocity.
Type of quantity?
there are two types of quantities - Scalars and vectors. Scalars are quantities which intrinsically have the property of magnitude only. Vectors are quantities which intrinsically have both the properties of magnitude and direction.
What quantities have both a magnitude and a direction?
Those are called vectors.

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.
What is parallelogram law of vectors?
"If two vector quantities are represented by two adjacent sides or a parallelogram then the diagonal of parallelogram will be equal to the resultant of these two vectors."
What are the different derived quantities?
Scalar and vector quantities. Scalar quantities only have magnitude, like the volume of an object. Vectors have both magnitude and direction, like the velocity of an object.
Which type of quantities can be expressed by arrows?
Vectors The arrow implies a direction as well as a magnitude.
Is resultant a vector quantity?
The resultant of two vectors cannot be a scalar quantity.
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.
Vector addition allows you to add what two quantities for any number of vectors?
