Is Energy Scalar or Vector, and How Does Dimensionality Affect It?

[big_bounce]

Someones like teachers in my country says energy is vector and scalar .
Is that true ?
Anyone can prov that ?

 

[Pengwuino]

Energy is a scalar. What gave you the impression it could be a vector?

 

[HallsofIvy]

Force is a vector, energy is a scalar. Perhaps you are confusing the two?

Energy is a scalar. If it were a vector then conservation of energy would fail during uniform circular motion in a radial potential and many other situations.

My friends in physics discipline and some teachers in university !

I Search web and find this :

I'm confused .

Answer2:
Yes. Energy is a scalar and a vector. Energy is a Quaternion quantity consisting of a scalar and three vectors, forming a 4D quantity.Early scientists started with scalar quantities. With Faraday's field theory (directed lines), vectors came into physics.However, the early definition of energy as scalar persisted to this day.
Vector energy is all around us, but we are blinded by dogma. F.D is called energy, but FxD is vector energy but is called Torque.I think we are about to lift the blindness. "Dark Energy" in Astronomy is vector energy. The Dark Energy is cmV = cP. Here is vector energy, Momentum energy. Momentum is a vector and Momentum energy cP is also a vector. A scalar c times a vector is a vector ! If there is vector momentum, there must be vector energy!
The correct Equation off Gravitation Energy is E = -mGM/r + mcV = -mu/r + cP.Newton did not include the vector energy cP=cmV. This was equivalent to saying the mass m, had velocity zero , E= -mu/r + mc0. Such is NOT the case. This is like saying the Earth is orbiting the sun with velocity 0, when it is moving at 30km/s. it is the vector energy cmV that provides the centrifugal force to keep the Earth from falling into the sun. It is the vector energy that is the "dark Energy" that is the anti-gravity (centrifugal) force. Vector Energy removes teh mystery of "Dark Energy".
Newton's Three laws are derived from this vector energy, that Newton incorporated.Force F = XE = [d/dr, DEL] m[-u/r , cV]F = m[v2/r - cDEL.V, cdV/dr +u/r3 R + cDELxV]

At Equilibrium 0 = F and DELxV=0 meaning R and V are parallel and. It is essential that DELxV =0 for the vectors to sum to zero.The result is

0 = m[v2/r - cv/r, cdV/dr + u/r3 R ]
Equilibrium Condition exists when v/c=1 or v=c.
Newton's Equal and Parallel phrase comes form

0 = m(dV/dt + u/r3 R) comes from

0 = cdV/dr - DEL u/r

Newto added the term 'mdV/dt' a vector, before vectors, This term is the vector energy P=cmV and dcP/dr = cmdV/cdt = mdV/dt, voila!

It is time to recognize that we live in a 4D Universe and Energy is a 4D Quantity.

You've stumbled on a crackpot. Telltale phrases: "we are blinded by dogma", "we are about to lift the blindness".

That looks wrong.

While it is possible to combine momentum and energy in the (stress-)energy-momentum-tensor, "energy" (density) is a scalar component of this tensor.

...forming a 4D quantity...but FxD is vector energy

The cross product does not work in 4D
