What would happen if the weak force stopped?
If the weak nuclear force ceased to exist radioactive decay involving the conversion of protons into neutrons and vice versa would no longer be possible. If either force ceased to exist all stars would be unable to produce energy by fusion. The Universe would become a very cold place.
Why weak force is important?
The weak force plays an important role in nuclear fusion, the reaction that powers the sun and thermonuclear (hydrogen) bombs. The first step in hydrogen fusion is to smash two protons together with enough energy to overcome the mutual repulsion they experience due to the electromagnetic force.
How does the weak force affect us?
As a result, the subatomic particles decay into new particles, according to Georgia State University’s HyperPhysics website. The weak force is critical for the nuclear fusion reactions that power the sun and produce the energy needed for most life forms here on Earth.
Is the weak force attractive or repulsive?
Concept Connections: The Four Basic Forces
| Force | Approximate Relative Strengths | Attraction/Repulsion |
|---|---|---|
| Gravitational | 10−38 | attractive only |
| Electromagnetic | 10–2 | attractive and repulsive |
| Weak nuclear | 10–13 | attractive and repulsive |
| Strong nuclear | 1 | attractive and repulsive |
Is weak force attractive or repulsive?
What does the weak force attract?
The weak nuclear force is usually responsible for turning protons into neutrons or vice versa. It also applies to more exotic particles containing strange, charm, up and down quarks.
Which shows the correct order of forces from weakest to strongest?
Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
