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

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 quantities are vectors?
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.
What is the name given to the physical quantity which can be completely described by specifying both magnitude and direction. name four such quantities?
That's a 'vector'. Examples include displacement, velocity, acceleration, force,momentum, torque, gradient, divergence, and curl.Distance, speed, temperature, price, weight, energy, power, voltage, resistance,and duration are not vectors.
When does a cyclist appear to be stationary with respect to another moving cyclist?
when their velocity vectors are in the same direction and same magnitude
What quantities have both a magnitude and a direction?
Those are called vectors.
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.
Which type of quantities can be expressed by arrows?
Vectors The arrow implies a direction as well as a magnitude.
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 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.
What is a scalar and what is a vector?
physical quantities having magnitude but not direction are scalars e.g mass, distance,work,energy,temperature area,volume charge etc while those physical which hav direction as well as magnitude are vectors e.gtorque,velocity,displacement,weight,force etc...
What are the types of measurement?
Vectors and Scolars Vectors: have an magnitude and a direction Scolars: have an magnitude but have no direction
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
Is velocity scalars or vectors?
It is a vector since it has both a magnitude and a direction. Scalar quantities only have a magnitude.
Does the order of adding vectors affects the magnitude and direction of the vectors?
No. The order of adding vectors does not affect the magnitude or direction. of the result.
Is direction is important for equal vectors?
Equal vectors are vectors having same direction of action or orientation as well as same magnitude. If two or more vectors have same magnitude but different direction then they cannot be called equal vectors. This shows that direction is important for equal vectors.
What are the vectors?
Vectors are quantities that have both value and direction. Such as displacement and Velocity.
