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 momentum a vector or scalar quantity?
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
Is angular momentum a vector quantity?
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.
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 hidden in plain sight, cP.
What does it mean to say that momentum is a vector quantity and that energy is a scalar quantity?
In a vector quantity, it is important to specify a direction. In a scalar quantity, it isn't. Vectors (such as force) have a magnitude (size) and a direction (such as North). Scalars have only a magnitude.
What formula of momentum?
The units are KgMs- why? Velocity is a vector Quantity and mass is a scalar quantity.
Is momentum a vector or scalar quantity?
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
Is momentum a vector?
Momentum is a vector quantity because the definition of momentum is that it is an object's mass multiplied by velocity. Velocity is a vector quantity that has direction and the mass is scalar. When you multiply a vector by a scalar, it will result in a vector quantity.
Is angular momentum a vector quantity?
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.
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 .

What is the energy 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 formula of momentum?
The units are KgMs- why? Velocity is a vector Quantity and mass is a scalar quantity.

Is momentum a vector quantity?
Yes momentum is a vector quantity. Because p = m v. As m is scalar and v is vector then p the momentum has to be a vector. Here m is mass and v is velocity
Is gravitational potential energy a scalar or vector quantity?
Gravitational potential energy is a scalar. Gravity also has a vector energy cmV= cP.
Is momentum a scalar quality?
A vector quantity is one which transforms like the coordinates. In other words, if a coordinate system is transformed by an operator , any vector quantity in the old coordinate system can be transformed to its equivalent in the new system by the same operator. An example of a vector quantity is displacement (r). If displacement is a vector, the rate of change of displacement (dr/dt) or the velocity is also a vector. The mass of an object (M) is a scalar quantity. Multiplying a vector by a scalar yields a vector. So momentum, which is the mass multiplied by velocity, is also a vector. Momentum too transforms like the coordinates, much like any other vector. The definition of a vector as a quantity having "magnitude and direction" is simply wrong. For example, electric current has "magnitude and direction", but is a scalar and not a vector.
What is the energy of moving parts 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 should vome to realize that Energy is Quaternion quantity consisting of a scalar part and a vector part. The Cosmos consists of scalar and vector quantities. The proper term for energy of a moving object is vector energy. The two terms for energy can be called, Boson/scalar and Fermion/vector energy.
