Physics is intriguing to many and completely unfathomable to others with its complex laws and theories. The laws of mechanics usually flummox even brilliant students at their first try. Here’s a quick guide to help you learn as to how you should approach studying the classical laws of mechanics in physics.
#1: There is no classical mechanics without Newton, learn about him first!
Sir Isaac Newton was the one who came up with the laws of mechanics. He was a brilliant physicist and his numerous theories have become the foundational fabric for physics as we know and learn today. He devised/formulated three basic laws for mechanics based his observation of objects with a concrete mass. Even today, these laws are relied upon heavily by various scientists to postulate new theories and laws.
#2: How did Newton discover these laws and theories – explore this idea
It is always important to understand a particular law or discovery came about from the very genesis of the idea to its form as it is being used today. Also, learn as to how later discoveries affected Newton’s theories and why they post different ideas, where they are applicable and what is the fundamental difference between the theories. These are sure to give you an idea as to the bigger picture; most online physics tutors recommend this line of thought for their students to help them explore recent and more relevant trends and how what they study is till date applicable and so on. Not only does such a practise help sharpen the mind; it also helps develop a good study method.
#3: How can you apply classical mechanics in the real world?
Whatever you learn will or would have had significance in real world situations. Learning as to how classical mechanics is relevant in the modern world will help you understand the topics in question better for you will be able to apply your learning. Here’s a list of areas where classical mechanics is used in today’s world:
- Automotive and aerospace industries
- Constructions such buildings and bridges
- Anything to do with travel such as travel to outer space and so on.
Students are usually given assignments in the area of classical mechanics to help them improve and apply their knowledge of it. Learning about such real world applications can prove to be effective physics assignment help!
#4: Learn other theories in the field
Hamilton and Lagrange postulated theories in the area of mechanics and these are famous too! Learn as to how these are different from Newton’s laws, where they are used and so on to master the laws of classical mechanics.
#5: Learn the three laws of mechanics as postulated by Newton in depth
Studying each law separately along with its applications will help you explore the concept in depth. While the first law of mechanics dealt with energy conservation and is also called the first law of thermodynamics, the second law is the very popular ‘F=ma’ law that tells us about acceleration and how objects behave under the influence of gravity during free fall. The third law is about the equal and opposite reaction of a force which is employed in rocket science to this day. Taking time out to work on each of these laws and understanding them in their entirety is essential. Getting yourself practise problems on these apart from whatever is given in your textbook could be the best physics homework help you could ask for!
Summary
To master fundamental laws such as the laws of classical mechanics by Newton requires a methodical approach and a lot of patience and hard work. Working out extra problems, understanding applications and working on projects that employ these laws will help students get a firm grasp of the underlying core concepts and help them score top marks in exams.
