Work is scalar
Work W is both a scalar (F.D) and a vector (FxD), in short work is a Quaternion,
W = [0,F][0,D]= [00 -F.D, 0D + F0 + FxD] = [-F.D, FxD] .
Physics has yet to recognize that Work and Energy are Quaternions and thus define work and energy as a scalar. Nature and mathematics recognize work as as a Quaternion manifested by the reality of F.D and FxD.
Work is a scalar when the angle between F and D is a multiple of even 90 degrees and a torque when the angle is an odd multiple of 90 degrees.
Work is both! The product of vector force F and vector displacement D gives two terms:
Work W= [0,F][0,D] = [0 - f.D, 0 + 0 + FxD] = [-F.D, FxD] .
Scalar work Ws= [- F.D,0]= -FDcos(FD)
and Vector Work Wv =[0, FxD]= FDsin(FD)v
When F and D are parallel work is a scalar, when F and D are perpendicular, work is a vector, otherwise, work is both a scalar and a vector.
Work like many quantities in Physics is a combination of a scalar and 3 vectors, in short a Quaternion quantity.
Velocity is a vector.Its magnitude is called 'speed'.
Gravity is a force, and forces have magnitude and direction; hence, it is a vector.
no, it's a vector dude
A vector quantity has both size (magnitude) and direction involved but a scalar quantity only has size involved and not direction.
We generally think of electric current as a scalar quantity. When we think of 1/4th amp or 20 amps, we think of an amount (a scalar quantity) of current flow. On another plane, the electromagnetic forces at work in current generation are actually force vectors. In the traditional sense, electric current, which is the movement of electrons, is from negative to positive. This is not a vector, though. In the macro or "large" world, think of current as scalar.---------------------------------------------------------------------The beauty is that though current is not a vector definitely its direction of flow is used to make length as vector. I is not vector. dl is not vector but I dl will be considered as vector. So innovative and essential concept.Current density is a vector which appears in Maxwell's equations.
Work is a scalar quantity.
Work is a scalar.
scalar lol
A scalar times a vector is a vector.
vector
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
It is scalar. This simply means that - unlike vector quantities - energy is not defined in a particular direction.
Work is the product of a force a nd a displacement. Both of those are vectors. There are two ways to multiply vectors. One of them produces another vector, the other produces a scalar. The calculation for 'work' uses the scalar product. The procedure is: (magnitude of one vector) times (magnitude of the other vector) times (cosine of the angle between them). Answer2: Work is a scalar because Physics has a major defect in defining energy as a scalar. Nature defines energy as a Quaternion, the sum of a scalar and a vector. Work is a Quaternion, W = FD= -F.D + FxD , -F.D is a scalar and FxD is a vector. Physics defines Work as -FDcos(FD) and defines FxD = FDsin(FD) as Torque. When Physics understands Nature and Quaternions, then both F.D and FXD will both be recognized as energy, scalar energy and vector energy.
vector, power= work/time and work= force * distance, force is vector.
current is vector or scalar
vector
scalar direction is a vector quantity
