Newtonian mechanics, also known as classical mechanics, is a branch of physics that describes the motion of objects based on the laws formulated by Sir Isaac Newton. These laws include Newton's three laws of motion, which explain how objects move when acted upon by external forces. Newtonian mechanics is used to study the motion of everyday objects and is essential for understanding the behavior of systems ranging from simple projectiles to complex planetary motion. **

The Newtonian fundamental law called the principle of action, also known as the principle of least action, states that the path taken by a system from one point to another is the one that minimizes the action. In other words, it describes the behavior of a physical system in terms of a quantity called action, which is the integral of the Lagrangian over time. This principle is a foundational concept in classical mechanics and is used to derive the equations of motion for a wide range of physical systems. It provides a powerful and elegant framework for understanding the behavior of particles and fields in classical physics. **

The Newtonian principles refer to the three laws of motion formulated by Sir Isaac Newton in the 17th century. These principles are: 1) The law of inertia, which states that an object will remain at rest or in uniform motion unless acted upon by an external force. 2) The relationship between an object's mass, acceleration, and the force applied to it, known as F=ma. 3) For every action, there is an equal and opposite reaction. These principles laid the foundation for classical mechanics and are fundamental in understanding the behavior of objects in motion. **

The third Newtonian law, also known as Newton's third law of motion, states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object. In other words, forces always occur in pairs, and the two forces are equal in magnitude and opposite in direction. This law is fundamental in understanding how objects interact with each other and is crucial in the study of mechanics and motion. **

Newtonian principles in physics refer to the fundamental laws of motion and gravitation formulated by Sir Isaac Newton in the 17th century. These principles include Newton's three laws of motion, which describe the behavior of objects in response to forces, as well as the law of universal gravitation, which explains the attraction between objects with mass. Newtonian principles provide the foundation for classical mechanics and are still widely used to describe the motion of everyday objects and celestial bodies. **

Yes, blood is considered a non-Newtonian fluid. This means that its viscosity, or resistance to flow, changes depending on the force applied to it. In the case of blood, its viscosity decreases as the force or shear rate increases, allowing it to flow more easily through blood vessels. This property helps blood to efficiently circulate through the body and adapt to changes in flow conditions. **

The three Newtonian axioms are: 1. Every object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. 2. The rate of change of momentum of an object is directly proportional to the force acting upon it, and this change in momentum occurs in the direction of the force. 3. For every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object exerts an equal force in the opposite direction. **

To adjust a Newtonian telescope, you need to align the mirrors properly. Start by adjusting the secondary mirror to ensure it is centered and angled correctly. Then, adjust the primary mirror by using a collimation tool to make sure it is properly aligned with the secondary mirror. Finally, fine-tune the focus by adjusting the eyepiece until the image is sharp and clear. Regularly checking and adjusting the alignment of the mirrors will ensure optimal performance of the Newtonian telescope. **
