Physics Quiz: Do You Know the Laws of Science?

The universe around us conforms to certain regular laws, painstakingly discovered by centuries of erudite scientists like Newton and Einstein. Luckily, we don’t need to be as wise as those great men to understand our world as well they did, we just need to pay attention. Let’s see how well you know these immutable physical laws by taking this tricky test!

You Can Do Better...
You still have quite a bit to learn about the way our universe works. But not to worry, there is so much to learn no one knows it all! The most important thing is to keep being curious and be willing to learn more.
That's Pretty Good!
You didn't answer all correctly but you can certainly hold your own when it comes to discussing this universe of ours. You have some more to learn, but don't we all? You certainly have a scientific curiosity.
Congratulations! You got top scores!
You know so much about physics, you could easily teach it! In fact, we hope you are. You stand on the knowledge of giants. Like them, you like to know and understand the world around you. This is a great attitude to life!
