Pathology is the branch of medical science that deals with the study of diseases and their effects on the structure and function of the body. Pathologists, experts in this field, investigate the causes, mechanisms, and patterns of diseases. They analyze tissues, organs, and bodily fluids to diagnose illnesses, understand their progression, and contribute to treatment plans. Pathology encompasses various specialties, including anatomical pathology (studying tissues and organs) and clinical pathology (analyzing bodily fluids like blood and urine). It plays a crucial role in medical diagnostics and research.
Sir Isaac Newton formulated three laws of motion, which are fundamental principles in classical mechanics. First Law (Law of Inertia): An object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by a net external force. In simpler terms, objects resist changes in their state of motion. Second Law (Law of Acceleration): The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The direction of the acceleration is in the direction of the net force. Mathematically, F=m×a, where F is the force, m is the mass, and a is the acceleration. This law explains how the velocity of an object changes when subjected to an external force. Third Law (Action and Reaction): For every action, there is an equal and opposite reaction. If object A exerts a force on object B, then object B simultaneously exerts a force of equal magnitude in t...
