What parts of physics are very difficult to comprehend?

Physics is hard to understand when all the student does is expect to plug in numbers into an equation and get the "right" answer. Physics is nothing without understanding what the units mean in the real world. In elementary and middle school, students learn about units for the first time such as meters, seconds, and centimeters.It is not until physics that these units get put into practical use.

For example, a lot of physics students complain about learning kinematics equations. Kinematics equations are just the addition and subtraction of unit quantities specific to a scenario.So if a scenario does not require an initial velocity, then you use a kinematics that does not have the initial velocity variable. No part of physics is hard to comprehend as long as the student knows what the problem is looking for and how to manipulate the units of what he or she is given to get the desired final unit of the answer.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
