probably yes
No, mass and energy are not scalars. Mass is a scalar quantity while energy is a scalar 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.
energy from the sun
Yes. Energy is a scalar quantity. Doesn't matter what kind of.
Gravitational potential energy is a scalar. Gravity also has a vector energy cmV= cP.
Electrical Potential Energy is a scalar or real number. Ep = zc e2 /4pi r.Total Energy is a Quaternion, the sum of the real or potential energy and the vector energy, Ev= mcV;E = Es + Ev = zc e2 /4pi r + mcV where Ev = mcV and V is the vector velocity.
Yes.

No, kinetic energy is a scalar quantity, not a vector. It only has magnitude and no direction.
The five different forces are the derivatives of the Quaternion Energy E=Es + Ev=[Es,Ev] where Es is the Scalar Energy and Ev the vector Energy. Force = XE = [d/dr,Del][Es,Ev] = [dEs/dr -Del . Ev, dEv/dr + Del Es + DelxEv] dEs/dr the scalar derivative of the Scalar Energy, the Scalar Centripetal Force Del.Ev the Divergence of the Vector Energy, the Scalar Centrifugal Force dEv/dr the scalar derivative of the Vector Energy, the Vector Tangent Force Del Es the vector Derivative of the Scalar Energy, the Vector Gradient Force DelxEv the Curl of the Vector Energy, the Vector Circulation Force.
A vector has magnitude and direction. A scalar has magnitude only. A car moving 60 mph North has a specific amouunt of kinetic energy, according to the formula KE = 1/2 * mass * velocity squared. If the car is moving 60 mph South is the KE the same?? ..Yes! Energy is a scalar! Nothing squared is a vector!! Length has direction. area does not
