The Basics of Mechanics
Mechanics is the study of objects in motion. From the movement of simple machines like bicycles, to the motion of atoms in space, mechanics is used to describe, explain and predict the behavior of objects that are in motion. Mechanics can be divided into two branches: classical mechanics and quantum mechanics.
Classical mechanics is the study of things that are moving at speeds that are NOT close to the speed of light. Classical mechanics seeks to understand how objects move in response to forces and is based on the concepts of Newtonian mechanics developed by Sir Isaac Newton. Newton’s three laws of motion are the basis of classical mechanics and state that a body at rest will remain at rest unless acted upon by an external force, that a body in motion will remain in motion in a straight line at constant velocity unless acted upon by an external force, and that for every action there is an equal and opposite reaction.
In contrast, quantum mechanics is the study of objects moving at speeds close tothat of the speed of light and is based on the principles of quantum physics. Unlike classical mechanics, quantum mechanics describes the motion of objects at a subatomic level. It is much more complex than classical mechanics as it involves principles such as wave-particle duality, the Heisenberg Uncertainty Principle, entanglement and quantum superposition.
In addition to classical and quantum mechanics, there are also two more branches of mechanics. Statics focuses on objects that are in equilibrium and does not involve motion. Dynamics is the study of motion and includes both classical mechanics and quantum mechanics.
In addition to the study of mechanics, mechanical engineering is an important branch of engineering that applies mechanics in the design, construction and operation of mechanical systems. Mechanical engineers make use of the principles of mechanics to improve the efficiency, safety and performance of machines. They also build machines that can operate in conditions where humans cannot, such as space.
Mechanics is a fascinating area of science that is essential to understanding the natural environment around us. Its basic principles allow us to understand and predict the behavior of moving objects in a variety of situations. It is also an essential part of the engineering field, allowing us to build powerful and reliable machines that can assist us in our day-to-day lives.
