Physics Important Formula

  1. Make a handmade note of all the formulas being highlighted. This would help in proper revision and a quick glance whenever required.
  2. One of the most powerful tools, not only for remembering formulas but also for solving typical Physics questions in JEE Exams is dimensional analysis. While preparing you could do a comparative study between chapters like electrostatics and magnetostatics.
  3. Apart from these, we can just memorize the basic formula like W = F.S and from this, we can deduce various other formulas like potential energy of a spring etc. We should memorize the value of different constants because people tend to confuse their values and that mistake will fetch you a negative marking.
