  2. Love of science and humanity  Click love of science and humanity. This link will give a collection of Powerpoint files (Physics for all-free material) that are helpful for students studying Physics in Grades 9 and above including college students with targets (IIT JEE, AIEEE, and other state-level entrance exams, CSIR-UGC NET, GATE, JEST, etc, and for interviews). Files are prepared more like notes than a presentation, for students to learn (Problem sets are also available). New sets will be updated periodically and the link will reflect those changes. Editing is disabled for the browser version. However, if you wish to make edits for personal use, the files can be downloaded and modified. All information is made available free of cost, with an appeal to donate for COVID-19 relief funds. Please share and support this noble cause.   Happy learning!! https://drive.google.com/drive/folders/15Ly9fqEiKxaVUCdFIrmRUg3calctXtNJ
