18. There are four fundamental forces of nature: strong force,
gravitational force, electromagnetic force, and the weak force.
What are examples of the first three? The protons and neutrons on an

atom are glued together via the strong force (which is broken when you
dump salt into water and measure the temperature increase).
Gravitational forces happen every time you throw a ball. Make the
electromagnet mentioned above experiment to demonstrate
electromagnetic forces.
