Fundamental Forces in Nature

The four fundamental forces of nature are: 

• Electromagnetism, Gravity, Strong Nuclear, Weak Nuclear
• Gravity, Strong Nuclear, Weak Nuclear, Medium Nuclear
• Normal Force, Force due to gravity, Magnetism, Nuclear 
• Nuclear, Electricity, Gravity, Atomic 

Rank the four fundamental forces of nature in order from weakest to strongest:  

• Electromagnetism, Gravity, Strong Nuclear, Weak Nuclear
• Weak Nuclear, Gravity, Electromagnetism, Strong Nuclear
• Gravity, Weak Nuclear,  Electromagnetism, Strong Nuclear
• Weak Nuclear, Electromagnetism, Gravity, Strong Nuclear

Gravity is due to:

• the pull between Earth and the moon.
• the pull between the Sun and Earth. 
• the pull between any objects with mass. 
• the pull between atomic nuclei.
