What is the *electroweak force*?
A unification of electromagnetism and the weak nuclear force. These 2 are actually different versions of the same force.
Which fundamental force is the *weakest*?
Gravity (gravitational force).
Which fundamental force is the *strongest*?

What is the *weak nuclear force*?
The force responsible for radioactive decay and nuclear fusion.
What is the *strong nuclear force*?
