Question

On what principle does the atomic bomb work?

Hint:

It involves splitting a heavy atomic nucleus, not joining two nuclei.

Answer 1

This question is about the physics behind atomic weapons.

1. Every atom has a nucleus made of protons and neutrons held together by strong nuclear forces.
2. In heavy elements like uranium-235, this nucleus can be split apart when hit by a neutron, a process called nuclear fission.
3. Splitting the nucleus releases a very large amount of energy along with extra neutrons.
4. These extra neutrons strike other nuclei and split them too, producing an uncontrolled chain reaction that releases enormous energy almost instantly.

So the answer is nuclear fission.
