Importance of Physics in Students’ Lives
When students in Singapore reach Secondary Three, they usually have to choose the combination of Science subjects that they wish to pursue for the national exams. One of the possible Science subjects is actually Physics, and it can be taken as a single subject called Pure Physics or a combined Science subject with either Chemistry or Biology. Physics is rather important in a student’s educational future, as good grades in the subject can open the doors to better tertiary and university courses such as Engineering and Aerospace. In addition, with a good diploma or degree, a student will be able to embark on a more successful and high paying career later in his or her life.
Now, while Physics is crucial to many aspects of students’ education, not many students are able to master it well. There are various complicated concepts, formulas and theories that students need to understand in Physics. When students are unable to cope with Physics, they usually turn to a home tutor for assistance. Let’s look at some of the challenging Physics chapters that students usually need help with from tutors.
Everything to Know About Physics
Before we get into the respective tough topics, let’s explore a little more on what Physics is all about. In simple terms, Physics involves the study and understanding of existing concepts such as energy and matter, and their relations to one another. Physicians usually apply models, patterns, concepts, and laws to learn about occurrences in nature, and understand how the universe behaves physically.
Challenging Topics in Physics
While there are numerous topics and themes in Physics, students generally find the themes and topics of magnetism and electricity to be rather challenging. It comes as no surprise then that the phenomena of electricity and magnetism are actually interlinked, making comprehension of these two themes and topics all the more difficult. Coincidentally, you can actually create magnetic fields by running electricity through a conductor (electromagnetism). Conversely, you can induce electric current whenever magnetic fields change directions in wired conductors (electromagnetic induction).
Students will be introduced to electricity first through the study of the properties of electric charges that do not move, or commonly known as electrostatics. Next, they will explore charges that move instead, with concepts such as electromotive force, voltage, current and resistance. Electromotive force and voltage deals with the amount of energy dissipated whenever a unit charge of one Coulomb moves around a circuit or two points, respectively. Current, on the hand, is the measure of the number of Coulombs of charges moving in a circuit per unit time. Finally, resistance is the amount of potential difference across a circuit divided by the current flowing in it. Once students have grasped the main electricity concepts, they will have to apply them in more complicated questions and calculations in the topics of direct current (D.C) circuits and practical electricity.
As though electricity is not tough enough, students will then be taught about magnets, their characteristics, and the interaction of magnetic fields. This is where it gets more interesting and difficult, when students have to explore the link between electricity and magnetism as they cover intricate topics such as electromagnetism and electromagnetic induction.
As you should be able to gather by now, mastering the topics of electricity and magnetism is no easy feat. Hence, many students look to tuition agencies such as FamilyTutor.sg to hire knowledgeable and good Physics tutors. These tutors will be able to get the students to comprehend the concepts better, and help them ace their Physics exams.
