# What does it mean to say momentum is a vector quantity and energy is a scalar quantity?

It means that in the case of momentum, the direction is relevant, in the case of energy, not.

Answer2.

It also means that science is still living in the past with respect to numbers. Scalars and vectors are quaternions. A scalar is a quaternion with an angle that is a multiple of 180 degrees. Q= cosA + vsinA = evA

Angles of 90 degrees are vectors. Other angles give quaternions, the sum of a scalar and a vector.

Energy can also be a vector like Torque = Force x Radius.

### Is potential energy a scalar or vector quantity?

Potential energy is a scalar quantity. Energy is the sum of a scalar part and a vector part. Energy W is the product of velocity V and momentum P; W = [c+V]P =[ -V.P + cP]. The Potential energy is the scalar energy -V.P=-vmv = -mv^2. Physicists consider energy a scalar quantity, but that is incorrect, energy is a Quaternion quantity, a scalar and a vector . The vector energy is the "Dark Energy" is…

### Is energy a vector quantity or a scalar quantity?

energy is a scalar quantity because energy does not has any direction . vector quantities need direction as well as magnitude. Answer2: Energy is like many concepts a Quaternion, i.e the sum of a scalar and a vector. Examples of vector energy FxD = Vector energy called Torque. cmV = cmV = cP is vector momentum (P) Energy. This energy is the so- called "Dark Energy".

### What is the energy associated with motion?

The energy associated with motion is the momentum energy cmV = cP. This is a vector energy, as momentum is a vector and c the speed of light. Physics currently considers energy a scalar quantiy, Nature considers energy a Quaternion Quantity, the sum of a scalar and a vector. The Momentum Energy cP is the mysterious "Dark Energy" that pervades the Universe, and is the energy associated with motion.

### What is the energy of any moving object called?

Vector energy. This term is not widely known or used. Physicists declare energy a scalar quantity, including the term kinetic energy. A moving object is uniformly assumed to have Momentum, a vector quantity.The energy associated with Momentum is Momentum Energy, cP (This is the widely looked for "Dark energy") Physicists use a term for another vector energy, Torque . Physicists use Joule for scalar energy and Newton-Meter for Torque, a vector energy. The Physics Community…
