# Classical Physics Questions Only Experts Can Answer

This is another physics gk quiz with questions primarily from Kinematics, a branch of classical physics where we study about motion without considering the causes of motion. Also, some of the questions are from other topics including materials and their properties. These questions will especially be helpful for school students and anyone who wants to test his basic physics knowledge.

These questions are framed keeping in view only the average requirements of learners and thus are mostly application-oriented. Play the quiz, and if it helps you, tell others about it.
