one sentence each

Answer 1

1a. Gravity A: Gravity is the attractive force between masses that acts over long distances and governs the large-scale structure of the universe.

1b. Strong Nuclear Force A: The strong nuclear force binds quarks into protons and neutrons and holds atomic nuclei together, being the most powerful force at subatomic ranges.

1c. Weak Nuclear Force A: The weak nuclear force causes certain types of radioactive decay and neutrino interactions by changing particle flavor via W and Z bosons and operates over very short ranges.

2. What are the four fundamental forces of nature? A: They are gravity, the electromagnetic force, the strong nuclear force, and the weak nuclear force.

3. What does electromagnetic force act on? A: The electromagnetic force acts on electrically charged particles (and magnetic dipoles), governing electric and magnetic interactions and electromagnetic radiation.

4. Which of the four forces is the strongest? A: The strong nuclear force is the strongest of the four fundamental forces, though its effects are limited to subatomic distances.
