A particle is a very small piece of matter that can have different properties, like mass and charge. There are different types of particles in the world, and they can be found in different ways. For example, some particles, like protons and neutrons, can be found in the center of an atom. Other particles, like electrons, can be found moving around the center of an atom.
Particles can also interact with each other in different ways. For example, some particles can stick together, while others can push each other apart. Scientists use different tools, like telescopes and microscopes, to study particles and learn more about how they behave. Understanding particles can help us learn more about the world around us and how it works.
