* Gravity: This is the force of attraction between any two objects with mass. It's what keeps us grounded and what makes the Earth orbit the Sun.
* Electromagnetism: This force arises from the interaction of electrically charged particles. It's responsible for a wide variety of phenomena, including:
* Electric forces: Attraction and repulsion between charged objects.
* Magnetic forces: Forces acting on magnetic materials or moving charges in magnetic fields.
* Strong Nuclear Force: This force holds the protons and neutrons together within the nucleus of an atom. It's extremely strong over very short distances.
* Weak Nuclear Force: This force is responsible for radioactive decay, where particles within the nucleus transform into other particles.
