How much do you know about Physics? It’s time to test your knowledge with this ultimate Physics quiz.

Physics is the science of matter which means that it studies everything that has to do with what it is made of, its motion but also its behaviour.

Understand physics (or at least the basics) is very important in order to understand how the world works.

From energy to force and the Big Bang, we will mention a bit of everything here.

You will find below 5 rounds of physics quiz questions with answers. Each round has a different level of difficulty as well as different types of questions. We will start with the easy ones and then move onto the medium and hard ones.
