Why Learn Physics Online?

Physicists can work in a wide range of research fields, as it occupies a large part of human activities. Those with physics skills up their sleeve are highly valued employees in different companies and organizations. 

Physics is the discipline for you if you’re curious about the world and want to know more about how things work. It will help you learn the physical laws for everything and find scientific explanations for various events. 

It is a profession that works hand in hand with technology and new energies, which allows workers in the area to be up-to-date and well informed about the latest trends and scientific discoveries. 

Online physics courses: why study physics

Or, maybe you simply want to explore some popular topics in physics? Even if you don’t plan to become an expert, studying physics will expand your mind and teach you some fascinating stuff you can apply in your everyday life.

Anyway, these online physics courses are a great way to dip your toes into the world of physics and see what it’s all about.

Many students choose to learn physics online for the following reasons:

#1 It’s a lot more affordable than degrees.

Not only that. As I said, most of what you’ll find in this article are free physics courses, provided by well-known universities. University degrees cost thousands, and while they are much broader programs than a single online course, it doesn’t mean you need it to gain the skills and knowledge you want.

#2 You choose what you want to study.

Why is that good? You can pick and choose courses that go hand in hand with your interests. Once you enroll in a degree, you have all the curriculum sorted out already, and there’s less room for changes. With online physics courses, you can start off by taking an introductory course, then move on to learn more about Einstein, waves or vibrations, electromagnetics, or whatever else it is you’re curious about.

#3 It’s very convenient.

You don’t have to worry about spending time and money on commuting to classrooms, you can simply log in and study whenever you have a free minute. While this does require certain time-management skills, it also makes it much more convenient to study from wherever you are. 

All you need is a laptop and a good internet connection to start learning.

#4 You can work and study at the same time.

Many people who want to develop new skills find a hard time combining studies with a full-time job because they don’t have control over the timetable of the lessons. Online physics courses are great because you can study at any time, whether it's 5 pm in the evening or 6 am in the morning on a Sunday

#5 Online physics courses take a relatively short time to complete

Most courses focus on one subject at a time, so in essence, they’re much shorter.

Also, because you study at your own pace, it means you can finish it a lot faster than a classroom-based course. Of course, if you tend to somewhat procrastinate (zero judgment, I do that sometimes too), you have to be extra careful about your study ethics.

#6 You can study at your own pace

In relation to the point I made above, studying at your own pace is a really attractive feature of online physics courses. There’s no pressure to speed it up, as it tends to sometimes happen in classrooms. If there’s a subject you find more challenging, you can spend as much time on it as you like

Plus, since all the teaching material is recorded, you can rewind or fast-forward it until you’re 100% sure you understand everything the instructor has to say.

Likewise, if you’re quick to learn certain topics, you can move on to the next subject whenever you like. 

Quality Courses by Top Universities

Online physics courses in this article are university-level courses taught by experts in their field. Today, you’ll find physics classes online organized by the Australian National University, University of Virginia, University of Massachusetts, Stanford University, and the University of Tokyo

Online physics courses: equations

You should know that whatever course you choose today, has been taken by many other students like you. All the courses have received a lot of positive feedback and are rated at no less than 4.5 stars

Nevertheless, you should still carefully read the syllabus and prerequisites of the course you’re interested in, to avoid the not-so-nice surprises. In the description of each course, you’ll find what topics are covered, and the main things you need to know before you enroll

Free Online Physics Courses

Many of the courses you’ll find in this article are free online physics courses

EdX allows you to access all the material for free, you only have to pay for the certificate if you wish to receive one.

Coursera also has free physics courses, although it works slightly differently. You can “audit” all the courses for no extra fees, with restricted access to some of the quizzes and student communities. If you purchase the full program experience, you get all this plus instructor feedback and a certificate. 

I have some good news though: if you’re not too eager to pay the full price, but still want to enjoy the perks of paid courses, you can use coupons. There are some great deals available, accessible right now!

You’ll also find top deals available in the descriptions of paid courses, so look out for those!

All right, are you excited yet?

How do you choose which online course sites to review?

We pick online learning platforms according to their market size, popularity, and, most importantly, our users’ request or general interest to read genuine MOOC reviews about certain online learning platforms.

How much research do you do before writing your e-learning reviews?

Our dedicated MOOC experts carry out research for weeks – only then can they say their evaluations for different aspects are final and complete. Even though it takes a lot of time, this is the only way we can guarantee that all the essential features of online learning platforms are tried and tested, and the verdict is based on real data.

Which aspect is the most important when choosing the best online learning platforms?

It wouldn’t be right to pick just one aspect out of the selection: priorities depend on each individual person, their values, wishes, and goals. A feature that’s important to one person can be utterly irrelevant to the other. Anyhow, all users would agree that good quality of the learning material is a must for online learning platforms.

How is this e-learning review platform different from others?

Every MOOC-reviewing platform is unique and has its own goals and values. Our e-learning reviews are 100% genuine and written after performing a careful analysis. That is the goal that a lot of e-learning review sites lack, so we consider it to be our superpower!
