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.

What are scalar waves?
Scalar waves are a type of electromagnetic that works outside of physics. They have to do with points in space.
Why speed is scalar while velocity is vector?
Speed is scalar (that is, without direction) and velocity is a vector (speed plus direction) by definition in physics.
Is velocity a scalar or vecrore quantity?
The word "velocity", as used in physics, is a vector. If you want a scalar (you don't care about the direction), you would talk about the "speed".
Is amount of substance a vector or scalar quantity?
In physics, "vector" usually means that a direction is relevant. If you just have a number, as in "number of moles", then a direction is NOT relevant.
What does gradient mean in physics?
Gradient means the vector derivative (Del) of a scalar quantity, e.g. for the Gravity Potenttial/scalar energy, Del-mGm/r= mw2R.
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.

Is velocity speed?
As used in physics, the two are different. Speed is a scalar, velocity a vector.
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.
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 does gradient mean in physics?
Gradient means the vector derivative (Del) of a scalar quantity, e.g. for the Gravity Potenttial/scalar energy, Del-mGm/r= mw2R.
Work done is scalar or vector?
Physics as taught in high school would say that work is a scalar quantity.More sophisticated forms of physics would say that work done is a Quaternion, both a scalar and a vector.Work is bothw= [0,F][0,D]=[ 0 - F.D, 0 + 0 + FxD] = [-F.D, FxD] = -F.D + FxD. -F.D = -FDcos(FD) is scalar work out, andw= FxD= FDsin(FD) a vector called Torque.
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.
