We often comes across the problems in mechanics where we need to apply the law of conservation of energy where gravitational potential energy or gravity is involved . For solving such problems you can consider the following problem solving strategy,
Right hand rule for cross product:-
Consider that c is the cross product of two vectors a and b i.e.,
c=a x b
If direction of vector a is along the x axis and that of b along z axis then direction of vector c could be find using right hand rule for cross products.
1. Remind Yourself of Your Purpose – What are your goals in life? Where do you see yourself 5, 15, or even 25 years down the road? .Objectives and aims are one of the best sources of motivation, as they will keep you focused and enable you to “do whatever it takes” to accomplish your goals. The time that you spend studying now will help to make your future dreams and aspirations a reality.

What is Periodic Motion : In Physics, a motion that is regular and repeating is called Periodic Motion. The time to complete one full motion is called the Time period of the Periodic Motion
What is SHM: A Simple Harmonic Motion is a special case of Periodic motion where a physical quatity varies sinusoidally.In this Periodic motion the restoring force is directly proportional to the displacement. The object oscillates between two position and Motion is sinusoidally in nature.
1) Prepare a Schedule/Calendar for the studies.You only have 24 hours a day, 168 hours a week . Effective study time management means that you use your given time in the most efficient way. Therefore it is important to prepare a regularly updated schedule/calendar, where you:
a) write down all your scheduled tests
b) write down all tasks, assignments and duties,
c) record your planned leisure-activities, such as gym, etc.
d) Write an ordered list of what you need to get done.Prioritize the items on your list.
Introduction about physics and studying the subject This article is mainly about use of units in physics. But before going further let us first discuss about how to avoid problems that students face while studying physics. When you study physics you must have appropriate skills or you would have to struggle a lot while studying the subject. In my experience students fail to learn physics … Continue reading Use of units in physics
When you start preparing for competitive exams like PMT, IITJEE, AIEEEi am sure most of you face this question “From which book should I study Physics?”. There are lots of books available in the market in Physics for preparation of exams like IITJEE/AIEEE/PMT and it could be quite confusing choosing from numerous available options.I would advise you all to choose one good book for example NCERT book or concepts of physics by HC Verma for reading text and clearing your concepts in physics.
