Physics: Senior High School: 11th and 12th Grade Quizzes

If you play these quizzes until you get top marks, you’ll be getting A grades in no time!

Would you like a taste of the wackier side of physics? We thought you would.

Electrical force is roughly a billion-billion-billion-billion times stronger than gravitation. If you were standing at arm’s length from someone and each of you had one percent more electrons than protons, the repelling force would be enough to lift a weight equal to that of the entire Earth!

According to Big Bang cosmology, the universe is constantly expanding. One idea suggests that this expansion must not only slow down, but also go into reverse and cause a Big Crunch. Sounds like a yummy chocolate bar, doesn’t it? If there is a cycle of ‘bang, expansion, contraction, collapse, bang’, it could be that the universe plays out the same way it always does. Which means you might have been born, went to school, read this introduction, played the quizzes, got married, had family, died and then done it all over again. And again. And not even known it. Spooky eh?

The speed of light isn’t constant. You may believe that the speed of light is approximately 671 million miles per hour, which according to the laws of Physics, is the fastest thing around. Even a TARDIS can’t go that fast! However, this figure of 671 million mph refers only to the speed of light in a vacuum. Light slows down whenever it passes through something. It has been measured at traveling a very leisurely 38 mph at absolute zero through ultra-cooled rubidium. A TARDIS can certainly do better than that. Although we are not sure what would happen if we were to put a TARDIS in ultra-cooled rubidium.

It’s time to play some quizzes - let's get going.
