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


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.


How are scalar and vector quantaties alike?

Scalar and vector quantities are both used to describe physical quantities in physics. The key similarity between them is that they both involve numerical values. However, vector quantities also have a direction associated with them, while scalar quantities do not.


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.

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).


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.


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 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 quantities have both a magnitude and a direction?
