A scalar is a single force or quantity that is independent of other forces, such as speed. Speed can be 45 m/s or 60 mph. A vector is something that involves two forces, such as velocity which is speed AND direction. For example, velocity can be 5 m/s North.
In physics, a scalar is a physical quantity that is fully described by its magnitude (size) only and does not have a direction associated with it. Examples of scalars include mass, temperature, and energy. Scalars are different from vectors, which have both magnitude and direction.

What are scalar waves?
Scalar waves are hypothetical waves that are said to be able to travel faster than the speed of light. They are sometimes proposed in alternative theories of physics but have not been experimentally validated. Scalar waves are believed to have unique properties that could potentially have applications in communication and energy transfer.
How do you use scalar in a sentence?
In physics, a scalar is a quantity that has only magnitude, without a direction. For example, temperature is a scalar quantity because it only has a value (e.g., 25 degrees) without needing a direction.
A quantity that expresses magnitude but does not express direction?
Scalar. Scalars are quantities in physics that are fully described by their magnitude alone and do not have a direction associated with them. Examples of scalars include temperature, mass, and speed.
What are the properties of scalar quantities?
Scalar quantities in physics have magnitude but no direction. They can be added, subtracted, multiplied, and divided like regular numbers. Examples include mass, temperature, and speed.
Is amount of substance a vector or scalar quantity?
Amount of substance is a scalar quantity. It is a measure of the number of entities (such as atoms, molecules, or ions) in a sample, and does not have a direction associated with it like vector quantities.
In physics what is the meanig of scalar?
scalar means a quantity which has only value,but has no direction.
What is scalar field?
In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number, or a physical quantity.

What One property does a scalar have?
As opposed to a vector, a scalar has a single number. In physics, this is used in situations where a single number is enough to describe something.
Is velocity speed?
As used in physics, the two are different. Speed is a scalar, velocity a vector.
What are the major concepts of a scalar and vector quantity in physics?
That vectors are just scalars WITH a direction. (for example 50 miles is a scalar distance, but 50 miles north is a vector)
What is the use of dot product in Physics and explain?
Dot Products in Physics denote scalar results fmo vector products, e.g Work = F.D = FDCos(FD) a scalar result from the dot product of two vectors, F Force and D Displacement.

In work definition we use only displacement why we didn't use distance in work definition?
Some Physics definitions ignore the real world of Nature. Forces and distances are four dimensional including real and vector quantities. Work is defined as the scalar product of two vectors and ignores the scalar cross distances and vector cross products..Gravity is a scalar force and gravitatinal potential energy is mgh where mg is a scalar force and h is a scalar distance. This is not called work because it is not the scalar product of two vectors.Nature and Physics involves scalar and vector quantities, in other words Quaternion quantities. The Quaternion product of force and distance is:(f + F)(d + D) = (fd - F.D) + (fD + dF + FxD).Physics only defines work as F.D and ignores the other 'work' including Torque,FxD.
