Physics is one of the most essential of all the sciences. It’s been popular ever since the day when cavemen wondered why apples fall from trees. Devotees from Aristotle and Galileo to Isaac Newton and Robert Oppenheimer have all tried their hand at physics, and we know the world better for their effort.
So if you’re looking to enter into the annals of physics fame, these physics trivia questions and answers are a great place to start. Whether you’re an expert in quantum mechanics or are still stuck on the apple/tree question like the cavemen, you’re sure to learn something–and show off your knowledge!
Plus, if worse comes to worst, there are so many unknowns in the world of physics that you can always cross your fingers and hope a revolutionary theory will rewrite all the answers to make you right.
Once you’re done mastering this physics trivia quiz, enlighten yourself further with quizzes on nature trivia, science trivia, and chemistry trivia questions and answers.
