Question

How can you say that the Electromagnetic Force governs the structure of atoms and molecules, the dynamics of chemical reactions and the mechanical, thermal and other properties of materials?​

Answer 1

From walking on the street, to launching a rocket into space, to sticking a magnet on your refrigerator, physical forces are acting all around us. But all the forces that we experience every day (and many that we don't realize we experience every day) can be whittled down to just four fundamental forces:

• Gravity.
• The weak force.
• Electromagnetism.
• The strong force.

These are called the four fundamental forces of nature, and they govern everything that happens in the universe.
