Physics is the study of matter, energy and their interactions. It has many complex Mathematical calculations, formulas and theorems. The world of Physics keeps on changing with every new discovery. For Intermediate 2nd year students, Physics is an important subject, for those who want to pursue their career as a data analyst, lab technician, application engineer, etc. It is important to have skills and a good understanding of the subject, in order to score well in their examination. Competitive exam like AIEEE (All India Engineering Entrance Examination) and NEET (National Eligibility and Entrance Test) ask questions from intermediate 2nd year Physics syllabus, so it is advised to study Physics properly.

Important question of AP Intermediate 2nd year Physics provides students with an advanced level of questions, which will help scoring good marks in Physics examination. These important questions of Physics are beneficial from the exam point of view. Practice these important questions to know about the types of question asked in the examination, important topics and chapters with maximum weighatge etc. These important questions are most likely to be asked in the coming board exams.

Practising these important questions would clear conceptual knowledge and enhance subject knowledge. It is important for students to know the important topics covered in the AP Intermediate 2nd year syllabus of Physics to study efficiently. While studying for the board exam, students can plan accordingly, giving priority to the below-mentioned important topics.
