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

Pengwuino said:Energy is a scalar. What gave you the impression it could be a vector?
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.
...forming a 4D quantity...but FxD is vector energy
Energy is a scalar quantity. This means that it has magnitude (size or amount) but does not have a direction associated with it. Scalar quantities can be added or subtracted by simple arithmetic.
Yes, energy can be negative. This typically occurs when energy is being transferred from one system to another, resulting in a decrease in the energy of the first system and an increase in the energy of the second system.
Energy is measured in joules (J) in the International System of Units (SI). Other common units of energy include calories (cal) and kilowatt-hours (kWh).
Kinetic energy is a scalar quantity. It is the energy an object possesses due to its motion and is dependent only on the object's mass and velocity, not its direction.
Yes, energy can be converted from one form to another. This is known as energy transformation or energy conversion. For example, chemical energy in food can be converted to kinetic energy when a person runs, and electrical energy can be converted to light energy in a light bulb.
