ICSE Physics – 8

Physics is a  branch of science that studies the matter and its motion, along with its relation with energy and forces. There are various branches of Physics which includes electricity, motion, waves, sound, light and many more. From the smallest micro particles and atoms to the largest stars and the universe, Every such thing is covered by Physics.
