What is classical physics?
Q: What is classical physics?
A: Classical physics is the branch of physics that was developed before the 20th century. It studies things like movement, light, gravity, and electricity.
Q: How did classical physics change in the 20th century?
A: In the 20th century, physicists discovered two better ways to describe nature - the theory of relativity and quantum mechanics - which made classical physics less useful when studying very small or fast-moving objects.
Q: Who worked on developing new theories in the twentieth century?
A: Albert Einstein worked out his Theory of Relativity and people like Neils Bohr, Werner Heisenberg, and Erwin Schrödinger created quantum mechanics.
Q: When does classical physics not work?
A: Classical physics does not work when studying very small objects (around the size of atoms or smaller) or when studying objects moving very quickly (around the speed of light).
Q: What are some examples of topics studied by classical physics?
A: Examples of topics studied by classical physics include movement, light, gravity, and electricity.
Q: What two theories replaced classical physics in the twentieth century?
A: The two theories that replaced classical physics in the twentieth century were the Theory of Relativity and quantum mechanics.
