the gradient of a scalar function of any quantity is defined as a vector field having magnitude equal to the maximum space rate of change of the quantity and having a direction identical with the direction of displacement along which the rate of change is maximum.

What is definition of physical quantities?
a physical quantity is an amout or any property that can be measured.
What is meant by unit of a physical quantity?

Is weight derived physical quantity?
Answer: No, weight is not derived from any other quantity. It's a characteristic of something. You might be thinking that mass would be preferable since that does not vary with the gravitational pull exerted on the item being measured. Answer: It really depends on the system of units used. In the SI, a weight is a force, and therefore a derived quantity (the product of a force and an acceleration).
If you divide a force measured in newtons by a speed expressed in meters per second in what units will the answer be expressed?
1 newton = 1 kg-m/s2[Speed] = [m/sec]Force/speed = (kg-m/sec2) / (m/sec) = (kg - m - sec / sec2 - m) = kg/secThis quantity has little if any physical significance,which is probably why it's a unit without a name.
What are non physical quantities?
Those quantities which cannot be derived from any other such as length, mass, time, temperature, electric current, light luminosity are examples for fundamental physical quantities.
What is fluid gradient?
Usually a fluid gradient refers to the pressure gradient in any kind of fluid. It is a quantity that shows which direction and how fast the pressure changes around a location.

What does the inverse square law state?
any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity.
What is significance of correlation?
it shows any pattern that may emerge in any given set of date, this includes a positive or negative correlation. positive where a gradient goes from low to high negative where a gradient goes from high to low

In imperial system we what measure?
Any physical quantity, but in mostly obsolete units.
Why expectation values are used?
In quantum mechanics,we are not certain about any physical quantity(unlike classical echanics).So,here value of every physical quantity can only be approximated or expected
