If you’re planning to study science or engineering in university, you may want to consider taking a course on mechanics before starting your studies. Mechanics is the branch of physics that studies the motion and behavior of objects, and it provides the foundation for many other areas of science and engineering.

Here are some reasons why taking a course on mechanics before starting your university studies in science or engineering can be beneficial:

  1. Understanding the basics: Mechanics is a fundamental area of study in science and engineering. By taking a mechanics course before starting your university studies, you can gain a solid understanding of the basic principles that will be essential to your success in later courses.

  2. Practical applications: Mechanics has many practical applications in many scientific and engineering fields. By studying mechanics, you can gain insights into how physical systems work, and how to design and analyze real-world systems.

  3. Problem-solving skills: Mechanics is a highly mathematical field that requires you to solve complex problems using formulas and equations. By taking a mechanics course, you can develop your problem-solving skills and learn how to apply mathematical concepts to real-world problems.

  4. Preparation for university studies: Many science and engineering courses in university build upon the concepts learned in mechanics courses. By taking a mechanics course before starting your university studies, you can be better prepared for the rigors of university-level science and engineering courses.

  5. Competitive advantage: By taking a mechanics course before starting your university studies, you can demonstrate your commitment to your field of study and your willingness to go above and beyond. This can give you a competitive advantage when applying to universities and when seeking employment after graduation.

In conclusion, taking a course on mechanics before starting your university studies in science or engineering can be highly beneficial. Not only can it give you a strong foundation in a fundamental area of study, but it can also help you develop your problem-solving skills, prepare for university-level courses, and give you a competitive advantage. So if you’re planning to study science or engineering, consider taking a mechanics course to give yourself a head start.

Mechanics for Scientists and Engineers ePrep course is one of the ten ePrep courses specially developed to help NSF, NSmen and others to better prepare themselves for studies in universities in Singapore, or overseas. Poor foundation in mechanics, especially for those without going through A-level physics, has been a big source of difficulties faced by those doing conventional engineering such as mechanical or civil engineering, and physical sciences.

This university preparatory course on mechanics is developed in collaboration with the publishers of the popular physics textbook by Serway and Jewett.  The course comes with the textbook at no additional cost, together with excellent learning materials provided by the publishers and a retired NTU professor as the tutor.

While this university preparatory course on physics was designed to help NSFs, it is now opened to everybody and it is highly recommended, especially for those who do not have a strong foundation in physics but are doing engineering, science or technological courses.

Please note that this course, as well as the other ePrep courses provided by NTU, will soon also available at SF@NS LXP, the SkillsFuture@NationalService Learning eXperience Platform.

Why Mechanics is Important

Mechanics is a fundamental branch of physics that studies the motion of objects, forces, and energy in various systems. It serves as the backbone of many scientific and engineering disciplines, making it a crucial topic for students pursuing careers in these fields. Building a strong foundation in mechanics can greatly benefit such students, as it provides them with a deep understanding of the principles and laws governing the physical world. We present here the various reasons why building a strong foundation in mechanics is essential for students studying science and engineering.

Firstly, mechanics serves as the basis for many scientific and engineering concepts. Understanding the principles of mechanics is necessary for comprehending other scientific fields such as chemistry, and biology. It is also the foundation of engineering, which involves the application of physics principles to design, construct and maintain structures, machines, and systems. In other words, a solid understanding of mechanics is necessary for a student to excel in any scientific or engineering field.

Secondly, mechanics provides students with problem-solving skills. The study of mechanics requires students to apply mathematical and conceptual frameworks to solve complex problems. These problem-solving skills are invaluable in the fields of science and engineering, where students are often tasked with designing new solutions to real-world problems. By building a strong foundation in mechanics, students develop the ability to analyze problems systematically and formulate effective solutions.

Thirdly, mechanics promotes critical thinking skills. As students learn about the principles of mechanics, they are required to apply them to various scenarios and situations. This requires critical thinking and the ability to apply concepts to different contexts. In addition, mechanics encourages students to question and explore the fundamental principles of physics, which fosters a deep understanding of the physical world and promotes creativity and innovation.

Finally, building a strong foundation in mechanics helps students to develop essential skills for future careers. Science and engineering jobs often require individuals who possess a strong understanding of mechanics and the ability to apply it to solve real-world problems. By mastering mechanics, students will be better equipped to understand and navigate the complexities of these careers, as well as develop the skills necessary to contribute to scientific and technological advances.

In conclusion, building a strong foundation in mechanics is essential for students studying science and engineering. It provides a fundamental understanding of physics principles, problem-solving skills, critical thinking skills, and prepares students for future careers in these fields. Therefore, students should prioritize the study of mechanics to ensure they have a solid foundation for their academic and professional pursuits.
