physiology is the branch of biology that deals with the study of the normal functions and activities of living organisms and their parts. In the context of human physiology, it specifically focuses on understanding the mechanisms and processes that allow the human body to function. This includes the study of various systems such as the nervous, cardiovascular, respiratory, and muscular systems. Physiologists seek to explain how different organs and tissues work together to maintain homeostasis, ensuring the optimal functioning of the body.
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...
