There are four known fundamental forces of nature, which are the forces that govern the behaviour of all matter in the universe. These are:

  1. Gravity: This is the force that attracts any two objects with mass towards each other. It is the force that holds planets in orbit around stars, and stars in galaxies. The strength of the gravitational force between two objects decreases with distance between them.

  2. Electromagnetism: This is the force that causes charged particles to interact with each other. It is responsible for phenomena such as electricity, magnetism, and light. Opposite charges attract each other, while like charges repel each other.

  3. The strong nuclear force: This is the force that holds the nucleus of an atom together, and is responsible for the binding of protons and neutrons. It acts over a very short distance, and is much stronger than the other three forces.

  4. The weak nuclear force: This is the force responsible for certain types of radioactive decay, such as beta decay, in which a neutron decays into a proton and an electron. It also plays a role in certain types of fusion reactions, such as those that occur in the sun. It acts over a very short distance, and is much weaker than the strong nuclear force.

In addition to these four fundamental forces, scientists have proposed a hypothetical force called dark energy and dark matter. Dark matter is a form of matter that does not interact with electromagnetic force, but gravity, it is inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe, while dark energy is a hypothetical form of energy that is thought to be causing the accelerating expansion of the universe.



Some environmental forces in nature

  1. Quartz: Quartz is a very common mineral that has piezoelectric properties, meaning that it can generate an electric charge when pressure is applied to it. It is also a good conductor of electricity and heat.

  2. Tourmaline: Tourmaline is a complex mineral that can have a variety of colours and can exhibit pyroelectric and piezoelectric properties. It can generate an electric charge when heated or when pressure is applied to it.

  3. Calcite: Calcite is a very common mineral that has piezoelectric properties. It can generate an electric charge when pressure is applied to it.

  4. Apatite: Apatite is a mineral that can have a variety of colours and can exhibit piezoelectric properties. It can generate an electric charge when pressure is applied to it.

  5. Garnet: Garnet is a mineral that can have a variety of colours and can exhibit pyroelectric properties. It can generate an electric charge when heated.

  6. Kyanite: Kyanite is a mineral that can have a variety of colours and can exhibit piezoelectric properties. It can generate an electric charge when pressure is applied to it.

  7. Topaz: Topaz is a mineral that can have a variety of colours and can exhibit piezoelectric properties. It can generate an electric charge when pressure is applied to it.

  8. Barite: Barite is a mineral that can have a variety of colours and can exhibit piezoelectric properties. It can generate an electric charge when pressure is applied to it.

  9. Fluorite: Fluorite is a mineral that can have a variety of colours and can exhibit piezoelectric properties. It can generate an electric charge when pressure is applied to it.

  10. Selenite: Selenite is a mineral that can have a variety of colours and can exhibit piezoelectric properties. It can generate an electric charge when pressure is applied to it.

Please note that these minerals may have other properties as well, and that the electromagnetic properties depend on the specific crystal structure. Also, this list is not exhaustive.
