Contributed by: Laiba Kashif Have you been clueless about which website to refer to for the notes of Class 11 Physics for the Federal Board and Punjab board? Search no more. We’ve got you. We have assembled all the notes you need to study for this subject and score well in the HSSC-I exams. Want to know the best part? You can download the notes as well as just view them without downloading. Isn’t it a win-win situation now? Without further ado, let’s dig into the notes, shall we?
Chapter 1 – Measurements
The first chapter will introduce you to the important aspects of this subject. Chapter 1 talks about:
What is physics
- What is physics? If you say it’s the study of matter and energy, you’ve named two of the four fundamental forces. But you’ve left out the other two and a large part of what most people think of as physics, namely the relationship between matter and energy.
- Physics might be described as the science in which we never know what’s going on. Even when we think we know, it turns out we don’t. This is not because of incomplete data or inexact measurement; rather it’s because our theories are wrong. They’re simplified stories about reality that we tell to understand what’s going on. Every so often, a theory gets corrected with a new story that doesn’t fit quite as well with the old one but does give better results when tested against actual reality.
- Physics is therefore an experimental science. It can be argued that this is true of all sciences, but in physics it’s more obvious than in biology or economics, say. In all fields there are experiments one can imagine doing but cannot, for practical reasons or lack of funding or ethical concerns, which makes them effectively inaccessible to scientists. What distinguishes physics from other fields is that the experiments one imagines doing but cannot are often just as important as those one can do.
