Pretty much any serious statistical model or experiment on anything will use basic calculus to interpret data. Anything that exponentially grows or decays (radioactive matter, bacteria, population growth, etc.) Anything that's built to be structurally sound. Anything that uses the EM spectra (radio, microwaves, visible light, etc.) All scientific industries use calculus practically constantly. And on and on and on... In reality, it's rarely pure theoretical calculus that's being done. Rather, another branch of math based on and built from the principles and results of calculus is primarily used called differential equations. Don't forget integration, the other "half" of calculus. That is as equally important in your listed applications. Also, both theoretical and applied calculus use both differentiation and integration. Differentiation isn't a separate branch of maths, but one of the two major branches of calculus as a whole.
Some people find calculus easier, others find physics easier. There is no general answer.
Simple answer: Calculus involves derivation and integration, precal doesn't. Pre calculus gives you some of the algebraic, geometric and trigonometric understanding that is required to comprehend the concepts in calculus. Without the knowledge from precal, calculus would not be easily understood, as it is taught in schools today.
In short, no. Elementary calculus includes finding limits, basic differentiation and integration, dealing with sequences and series, and simple vector operations, among other concepts. Pre-calculus mostly focuses on the algebra necessary to perform those operations, with perhaps some introduction to limits or other simple ideas from elementary calculus.
Calc. has many applications. A few of them are calculating: work, area, volume, gradient, center of mass, surface area...
Some examples of real life applications include:1) Reactions in which a strong acid is used2) Trying to neutralize your stomach acids3) When eatingSources: acid-base-reaction
That depends on what your "real life" consists of. If you sell merchandise at a supermarket, or do carpentry work, you won't need such advanced mathematics. If you work in the engineering fields, you might need it at some moment like with electromagnetic fields, gravitational fields and fluid flow. If you are an engineer you will come across vector calculus to handle three dimensional space.
Its importance is tremendous - it has many different applications. Some of the applications include calculation of area, of volume, moment of inertia, of work, and many more.
Any bachelor's in business will require at least a pre-calculus, with some institutions requiring a brief calculus with applications. In addition, there will also be business statistical analysis.

There are lots of practical applications of calculus; you can some in the Wikipedia article on "Calculus". Here are some interesting applications: find the maximum or minimum of a function; find the area of arbitrary 2-D shapes or the volume of arbitrary 3-D shapes; analyze the shape of curves represented by mathematical relations; calculate physical quantities such as energy, moment of inertia, center of mass and others (this is related to calculating the area of arbitrary shapes), and others.

Some examples of real-world applications of inclined planes include ramps for wheelchair access, sloped roads for vehicles to climb steep hills more easily, and conveyor belts used in industries for transporting materials up or down.

Quick question are you doing the WS real-world applications?yes we are
There are many examples of daily life applications of real numbers. Some of these examples include clocks and calendars.
