Efficiency is a scalar quantity because it can increase in magnitude but does not have any particular direction. :)

∙ 11y agoKinetic energy is defined as scalar energy.
Physics is confused by defining energy as only scalar. Energy is a Quaternion quantity, consisting of a scalar energy and a vector energy.
I call vector energy kinetic energy, e.g cmV=cP kinetic energy.
This confusion can be seen by the product of a force vector F and a vector displacement D;
FD= -F.D + FxD = -FDcos(FD) + FDsin(FD) 1FxD,
The cosine term is scalar energy and is called energy by Physicists, but the sin term is not called vector energy , it is called "torque".
Failure to appreciate quaternions is a major block to understanding physics.
Second Kinetic energy is "defined" to be 1/2 mv2. This is wrong Potential energy
V = mv2, e.g mGM/r = mv2 so that w2 = GM/r3.
Quaternions is the key to understanding Physics.

Is scalar quantiy is added with vector quantity?
No, a scalar quantity cannot be added to a vector quantity directly. They belong to different types of quantities - scalars have only magnitude while vectors have both magnitude and direction. To add a scalar to a vector, you would need to convert the scalar to a vector by giving it a direction and then perform vector addition.
Is the following measurement a vector quantity or a scalar quantity?
A vector quantity.
The main difference between a scalar and a vector quantity is?
A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction. Scalars are represented by a single numerical value, while vectors are represented by both magnitude and direction, often using arrows.
Is kinetic energy vector quantity?
No, kinetic energy is a scalar quantity, not a vector. It only has magnitude and no direction.
What is scalar vector?
A scalar is a single quantity that is represented by just a magnitude, such as temperature or speed. A vector is a quantity that has both magnitude and direction, like force or velocity. Scalars can be thought of as a subset of vectors with zero direction component.
Is Moment Arm a scalar or vector quantity?
Moment arm is a scalar quantity, as it represents the perpendicular distance from the axis of rotation to the line of action of a force. It does not have a direction associated with it, unlike vectors.
Is the distance a vector or scalar quantity?
Distance is a scalar quantity, meaning it only has magnitude and no direction. It is a measure of how much ground an object has covered during its motion, without considering the direction.
A vector quantity has direction a scalar quantity does not true or false?
True, a vector quantity has direction, and a scalar quantity does not.
Which are the scalar quantities?
Scalar quantities are physical quantities that have only magnitude and no direction. Examples include mass, temperature, speed, and volume. These quantities are described fully by their magnitude alone.
Is pressure scalar or vector quantity?
Pressure is a scalar quantity. It is defined as the force per unit area and only has magnitude, not direction.
Is scalar quantiy is added with vector quantity?
No, a scalar quantity cannot be added to a vector quantity directly. They belong to different types of quantities - scalars have only magnitude while vectors have both magnitude and direction. To add a scalar to a vector, you would need to convert the scalar to a vector by giving it a direction and then perform vector addition.
Is temperature a scalar quantity or vector quantity?
temperature is a scalar quantity................
Electrostatic potential is a Scalar Quantity or Vector Quantity?
Electrostatic potential is a scalar quantity. It represents the potential energy per unit charge at a given point in an electric field.
Is AC a vector or scalar quantity?
AC is a vector quantity because it has both magnitude and direction. Velocity, force, and displacement are examples of vector quantities, and they can be represented by arrows in the appropriate direction.
Is length a scalar or vector?
Length is a scalar quantity. By definition, a vector quantity has both magnitude (ie. length) and direction. Length does not have direction, so it is not a vector. Length is a scalar quantity. Length is a scalar quantity. yes
Is length a scalar quantity or a vector quantity?
length is a scalar quantity buddy . but displacement is vector quantity. Length is a vector quantity If it is associated with direction.. Because having direction make it vector... S0 being vector or scalar depends upon how and where it is used..
Why cant a vector quantity be added to a scalar quantity?
vector quantity is magnitute and direction scalar is magnitute only
