NCERT Books are designed on the basis of National Curriculum Framework (NCF), which recommends that children’s life at school must be linked to their life outside the school. This principle marks a departure from the legacy of bookish learning which continues to shape our system and cause a gap between the school, home and community. Similar to this idea, NCERT Class 12 Physics books are also designed. The book vests the content totally reliable on strong concepts and healthy practices on the topic.Great Physicist and Nobel Laureate Richard Feyman said that, ‘Theories alone can never win you Physics concepts without practicing it’.
