QuestionShould I start learning physics through textbooks or through summary notes?Meredith Juncker is a PhD candidate in Biochemistry and Molecular Biology at Louisiana State University Health Sciences Center. Her studies are focused on proteins and neurodegenerative diseases.Everyone has different styles of learning, so identifying which style works best for you is a great place to start. Maybe summary notes would be a good place to find a point of interest and then using a textbook to go deeper into a particular concept would be helpful!

QuestionWhat should I do if I can understand the topic, but don't have the confidence to solve problems numerically?Community AnswerDo not concentrate on the numbers until the very end of any problem. Understanding the topic means that you understand the equations behind it, the derivations behind them, and especially being able to manipulate them symbolically. Improving your algebra and calculus techniques is a must. Drawing diagrams also helps greatly. Practice problems by solving them symbolically first, then plug in values.

QuestionDo I need to know math to do physics?Community AnswerYes. Math is the language of physics. You'll want to be really good at the level of math at which the course is taught.
-
QuestionHow should I begin to learn physics?Community AnswerGo to a quite place, and just concentrate on studying. You can purchase textbooks to use as resources. You should also practice any exercises that come with the textbooks to help you learn physics.
-
QuestionWhat kind of math do I need to know to learn physics?Community AnswerAlgebra 1 and 2 along with geometry. You might also use pre-calculus.
-
QuestionIs personal reading the best way of understanding a subject?Community AnswerFor some people, yes. For others, it's possible that being taught by someone else is more effective for understanding a subject.
-
QuestionHow can I learn the laws of motion?Community AnswerThe laws of motion are particularly easy to learn when you study Newton, which will be covered in any physics class.
-
QuestionIs a gravitational field magnetic?TomPNTop AnswererNo, they're completely different things. Gravitational fields are generated by objects with mass (e.g. the Earth). Magnetic fields are generated by magnets. It is possible for an object to have both, but they aren't the same.

QuestionHow do I understand the whole of physics in a short amount of time?Community AnswerLearning "the whole of physics" in a short amount of time is very difficult; however, you still can learn a lot of physics in a short amount of time. Start today: I suggest going to Khan Academy and doing their courses on physics. Take notes and review your notes from time to time. You can find additional resources for practice problems and more. Once you've gleaned the basics, seek out other books and online resources to learn the more advanced applications of physics.

QuestionCan I do science without physics?Community AnswerYes, science has many more fields but physics helps to give you an understanding of many aspects of science.
-
QuestionWhat do I do to understand physics calculations?Community AnswerLearn more about algebra 1, algebra 2 and calculus. Study your textbook and maybe join a study group so you can understand the subject matter through discussion with others.

QuestionI don't like to study physics but it's important for me. What can I do to concentrate on physics?Community AnswerLay down all your learning materials (including pencils and paper) on a clean working area. Make sure to find a quiet place to do this. Put alarms on your phone so that you don't work too long and take breaks occasionally (you'll get exhausted and stop paying attention). Have snacks nearby so you can eat while you learn. Every time you answer a question correctly, reward yourself somehow.

QuestionWhat are some examples of objects which have both gravitational and magnetic fields?Community AnswerEvery object in this universe has a gravitational field around it and by every object, that means everything, even the device you opened this website on. The difference is it is clearly experienced by some objects, due to their high mass but most objects have negligible gravitational field. So, any charged particle and magnet would have both gravitational and magnetic fields.
