Physics


Class - 8th DAV Subjects
Everything You need to know
 

Here, we will cover the various topics regarding Physics for Class 8. Physics is one of the most interesting but a bit confusing branch of Science for most of the students. The main goal of Physics is to understand how the universe behaves. Physics explains the Physical World i.e. the day to day life experiences, such as why it is easy to push a moving object that a stationary object or why is static friction more than rolling friction The concepts that are mastered in the lower classes help us to crack many entrance examination like JEE Main, JEE Advanced, UPSC etc. At ABHYASONLINE.IN you can master the concepts at your own learning pace. It provides conceptual testing with an analytical reports identifying the weak, moderate and strong concepts. We, at ABHYASONLINE.IN believe that, if the weak concepts are timely identified and improved, then every student can achieve their goals in life. Follow the links below to understand and master each and every concept of various topics in Physics along with video lectures.
