Core subjects are those that are common to most, or all skilled, trades. You can probably guess that mathematics, for example, is a universal requirement for all the skilled trades. That's absolutely correct. Not all trades require the higher levels of algebra, geometry, and even a bit of calculus. You need the math that is appropriate for your work and building your career.

Physics is important, too. An good introductory physics course helps you understand whey things behave the way they do -- from balancing loads to welding metals. And you will most likely find you need a basic understanding of electricity and electrical machinery as well.

Basic Physics for the Mechanical and Construction Trades

This is a lightweight introduction to the basic principles of physics. There is very little math required (you should know how to solve basic formulas).

Basic physics underlies the methods and standards for the skilled trades, most notably welding, construction, energy  generation and distribution ... well, the list is actually quite long. The really cool thing about knowing some basic physics is that you can better understand what you are doing and come up with solutions to the problems you face every day. Many kinds of expensive and harmful accidents can be avoided by a general understanding of how a few principles of basic physics apply to a wide range of real-world situations.
