Las fuerzas de la naturaleza

The video explains the four fundamental forces: gravity, electromagnetic, weak nuclear, and strong nuclear. Gravity is a weak force that attracts bodies based on mass and distance. The electromagnetic force is much stronger, affecting charges and holding atoms together. The weak nuclear force is crucial for element creation in stars, while the strong nuclear force binds atomic nuclei. These forces govern interactions at all scales.

What is the primary reason gravity is considered weak compared to other forces?

• It only affects small objects.

• It decreases rapidly with distance.

• It is weaker than the electromagnetic force.

• It only works in space.

Which force is responsible for holding electrons and protons together in atoms?

• Strong nuclear force

• Weak nuclear force

• Electromagnetic force

• Gravitational force

What role does the weak nuclear force play in stars?

• It keeps the stars from collapsing.

• It generates light and heat.

• It allows the transformation of protons into neutrons.

• It helps in the formation of black holes.

Why do atomic nuclei remain intact despite electromagnetic repulsion between protons?

• The gravitational force is stronger.

• The weak nuclear force counteracts it.

• The electromagnetic force is weaker in nuclei.

• The strong nuclear force overcomes it.

Which of the following is NOT one of the four fundamental forces?

• Weak nuclear force

• Nuclear force

• Gravitational force

• Electromagnetic force
