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 is scaler quantities and vector quantities?
Scalar quantities are physical quantities that have only magnitude, such as mass, temperature, and time. Vector quantities have both magnitude and direction, such as velocity, displacement, and force. Scalars can be added algebraically, while vectors need to consider both magnitude and direction in addition to standard arithmetic operations.
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.
What is scalar or vector qualities?
Scalar quantities are physical quantities that have magnitude only, such as mass or temperature. Vector quantities have both magnitude and direction, like velocity or force. Scalars are represented by single values, while vectors are represented by arrows indicating both magnitude and direction.
Why is it important to know whether a measurement is vector or scalar?
It is important because vectors have both magnitude and direction, while scalars only have magnitude. Understanding the distinction helps in determining how quantities behave in physical systems, making calculations more accurate. Additionally, vectors and scalars are represented and manipulated differently in equations, so identifying the correct type is crucial for correct math operations.
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.
Is the concept of vectors merely a convenience in expressing physical quantities?
No, vectors are not just a convenience in expressing physical quantities. They have magnitude and direction, which makes them essential in describing physical quantities like force, velocity, and acceleration accurately in three-dimensional space. Vectors are fundamental in physics and mathematics for representing quantities that have both magnitude and direction.
What physical quantities are represented by axial vectors?
Axial vectors represent physical quantities associated with rotational motion, such as angular velocity, torque, and angular momentum. These quantities have both magnitude and direction, and their direction is perpendicular to the plane of rotation.
What a examples of vectors?
Examples of vectors include velocity, force, and acceleration. These quantities have both magnitude and direction, making them suitable for representation as vectors. In physics, vectors are used to describe physical quantities that involve both size and direction.
What is represented by vectors?
Vectors represent physical quantities that have both magnitude and direction, such as force, velocity, and acceleration. They are commonly used in physics to describe these quantities in a mathematical way. Vectors are typically represented by arrows, with the length of the arrow representing the magnitude and the direction indicating the direction of the vector.
How do you classify physical quantities?
Physical quantities can be classified as scalars or vectors. Scalars have only magnitude, such as mass or temperature, while vectors have both magnitude and direction, like velocity or force. Scalars and vectors are further categorized into base quantities (e.g. length, time) and derived quantities (e.g. speed, acceleration).
What is the two types of physical quantities?
The two types of physical quantities are scalars and vectors. Scalars are quantities that only have magnitude, such as time, mass, and temperature. Vectors are quantities that have both magnitude and direction, such as velocity, force, and displacement.
What is vector in science?
In science, a vector is a quantity that has both magnitude and direction. Vectors are commonly used to represent physical quantities like force, velocity, and acceleration. Unlike scalar quantities that have only magnitude, vectors require both magnitude and direction to be fully described.
Which are considered vectors?
Physical quantities that have both magnitude and direction are considered vectors. Examples of vectors include force, velocity, acceleration, and displacement. These quantities are represented using arrows to show their direction and scale to show their magnitude.
Why are vectors considered to be vectors?
Vectors are considered vectors because they have both magnitude (size or length) and direction. This property distinguishes vectors from scalars, which only have magnitude. In physics and mathematics, vectors are essential for representing physical quantities like force, velocity, and displacement that have both size and direction.
What quantities have both a magnitude and a direction?
Those are called vectors.
What do you call a quantity with magnitude and direction?
A quantity with magnitude and direction is called a vector. Vectors are commonly used in physics to represent physical quantities like force, velocity, and displacement.
What is a quantity that has a direction associated with it called?
A quantity that has a direction associated with it is called a vector. Vectors are used to represent physical quantities that have both magnitude and direction, such as force, velocity, and displacement.
