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.
It can be important to know the velocity of an object not just its speed because?
We distinguish between speed and velocity because if you add the speedsof objects, their directions are important. For example, the velocity of an airplane with ...
Name a physical quantity that varies?
By "physical" quantity, I will "assume" you mean directly measurable. 1. Kinetic Energy 2. Temperature 3. Velocity 4. Heat 'content' 5. Radioactivity 6. Luminescence
What are the examples of vector?
Examples of vector quantity are displacement, velocity, acceleration, momentum, force, E-filed, B-field, torque, energy, etc.
Is force a derived quantity?
Yes, Force is a derived quantity. Force is the first derivative of Energy, F=XE.Force and energy are quaternion quantities consisting of a scalar S and a vector V.The scalar energy is called a potential energy like gravity Es=-mMG/r = -mu/r. The vector energy is Ev=mcV where V is the vector velocity.
What type of energy is velocity?
Velocity by itself is not an energy - it has different dimensions. Any object that moves has kinetic energy - calculated as KE = 0.5 x mass x velocity2.
Is tmperature a scalar quantity or vector?
A scalar quantity is a quantity that has only a magnitude value, whereas a vector quantity is a quantity with magnitude and a direction. Now when looking at speed vs. velocity, we know that the speed of an object can either be larger in magnitude or smaller in magnitude compared to a velocity where the object can be going in a specific magnitude but heading West, East, or North. This concept can be applied to temperatures. Temperature is a scalar quantity because it reveals the magnitude of the kinetic energy within that environment or object. If we look even deeper, kinetic energy or just energy is a scalar quantity, energy being the capacity to do work.
Is potential energy a scalar or vector quantity?

The vector energy is the "Dark Energy" is hidden in plain sight, cP.
How are kinetic energy and momentum differ?
Momentum is a vector quantity, depending on magnitude and direction, while kinetic energy is a scalar quantity and does not depend on direction.The formula momentum is p = m•v, and for Kinetic energy, KE = 1/2mv2, where m is mass in kg and v is velocity in m/s. This means that momentum is directly proportional to the velocity, and KE is proportional to the square of the velocity. For example, if you double the velocity, momentum is doubled, and KE is quadrupled.

If the equation E equals mc squared gives energy which is a scalar physical quantity how is this possible when multiplying a scalar and a vector results in a vector quantity?
Energy is a product of 1 scalar quantity which is mass and 1 vector quantity which is the velocity of light within a vacuum. The velocity of light in the equation is squared which returns an absolute value negating any sign it has. This results in both terms having no sign. A vector quantity must have both a direction and a magnitude. The product returned will always be a positive quantity which means it has no direction.
Why does load vary downstream?
This is the amount of load a river can carry. Generally, the load quantity will increase with discharge and velocity because rivers of higher discharge and velocity have more energy so will be able to carry more load. Therefore, load quantity increases downstream. Also, small particles require less energy to be carried so as the load size decreases, quantity increases
Definition of fundamental and derived units?
The fundamental quantities:TimeSpace (or length)MassTemperatureElectrical currentLuminosityAmount of matterA fundamental quantity is an irreducible "thing". It cannot be described in terms of other "things". This is in contrast to derived quantities, which can be described in terms of other "things". Fundamental quantities are also called base quantitiesFundamental quantities can be considered to be dimensions, but in a loose context. In physics, when we refer to dimensions, we usually refer to space and time (and theoretically higher similar dimensions), and not the dimension of the luminosity (see below).Each fundamental quantity has an associated unit in the SI system:Time: seconds (s)Space: meters (m)Mass: kilograms (kg)Temperature: degrees kelvin (K)Electrical current: ampere (A)Luminosity: candela (l)Amount of matter: moleDerived QuantitiesAll other quantities in physics can be expressed in terms of the fundamental quantities. Examples are velocity (space divided by time), acceleration (space divided by time squared), force (mass times space divided by time squared) or energy (mass times the constant representing the speed of light squared - aka. space divided by time all squared). Understanding this concept helps in understanding how all equations work, and how different "things" are related CommentThere are no such things as SI 'derived units'; the correct term is 'base units'.
