Explain Science

Physics

Physics is the study of the physical world around us, from the tiniest particles that make up everything we see, to the biggest structures in the universe. It is concerned with understanding the fundamental laws that govern nature, such as Newton’s laws of motion and Einstein's theory of relativity. Through experimentation and observation, physicists develop models that can describe and predict the behavior of different physical systems and phenomena.

  • An explanation of black holes for different age groups.
  • Convection currents are a process of heat transfer that occurs when heated particles become less dense and rise, while cooler particles become denser and sink, creating a circular motion that transfers heat.
  • An explanation of cosmic rays and their effects on Earth and the universe.
  • Density is a measure of how much mass is contained in a given volume. It is a fundamental concept in physics and chemistry.
  • This post describes the different types of electromagnetic waves that make up the electromagnetic spectrum and how they are used in our daily lives.
  • Electromagnetism is the branch of physics that deals with the interaction between electrically charged particles and their electromagnetic fields.
  • This post summarizes the concept of an electron, a subatomic particle that plays a critical role in atoms and molecules.
  • Friction is a force that opposes motion between two surfaces that are in contact with each other. It is caused by the irregularities on the surfaces that interlock with each other, creating resistance to the motion. Friction can play both positive and negative roles, depending on the situation. For example, friction can be helpful in walking or driving, as it provides the necessary grip between the feet or wheels and the ground. However, friction can also cause energy losses and wear and tear on machines and moving parts. The amount of friction between two surfaces depends on several factors, such as the nature of the materials involved, the temperature, the pressure, and the speed of the motion.
