Most people can admit that a large portion of the technology that drives today’s society comes from fundamental discoveries of Physics. It is the science associated with matter, energy, motion and force. Things such as computers, telecommunicators, transistors, microchips, lasers and nuclear powers are among the many layers of Physics that are so pervasive to this day. Here are some important aspects in Physics and their meanings:
Laws of Motion: Based on Isaac Newton’s laws of motion, there are three laws that define the relationship that lives between the motion of an object and the forces that enable that motion.
Energy: Energy consists of quantitative property and that property is transferred to an object so it can then perform its task. What is interesting about Energy is that according to the law of conservation of energy, it can be converted in form, but it can not be created nor destroyed.
Atoms and Molecules: Atomic and Molecular Physics focus on matter-matter and light-matter interactions. An atom is a small particle of any chemical element that may or may not exist independently. Molecules are a group of atoms that are bonded together.
Particles in Motion: Essentially, particles are objects that are in motion, which means they have kinetic energy. The faster the particle moves, the more kinetic energy it will have. Kinetic energy comes from heat, the faster the particle moves around in a substance, the hotter it will become.
Electromagnetism: This branch of Physics focuses on the electromagnetic force that happens between electrically charged particles. The electromagnetic force is part of one of the four fundamental forces and includes electromagnetic fields such as electric fields, magnetic fields and light.
Quantum Mechanics: This theory in Physics is fundamental and focuses on providing a description of any physical property in nature using a scale of atoms and subatomic particles. It gives an explanation of the nature and behavior of matter and energy on an atomic and subatomic level.
Physics can be appreciated in many different ways and offers a wide variety of types of information. Studies can range from focusing on objects of any size using quantum mechanics to the entire universe using general relativity.
