Agree with Wayne that "leverage" doesn't really cover what we do in Tai chi. Hydraulics is certainly better...
Mmm... Let me think...
Is pulling the rug out from underneath someone, putting a bana peel in front of someone's foot, or changing the direction of the water by the use of curvatures of pipes, more about "leverage" or similar to hydraulics? I would say way more the latter. But I am no expert in physics, so let's ask someone with the knowledge..
Me: What physical principles and terms cover redirecting motion and the manipulation of a mass in motion?
ChatGPT: Redirecting motion and manipulating a mass in motion involve various physical principles and terms, depending on the context. Here are some key concepts that might apply:
Newton's Laws of Motion: These laws describe the relationship between the motion of an object and the forces acting on it. For example, Newton's first law states that an object in motion will stay in motion unless acted upon by an external force. This principle is fundamental to understanding how to redirect or manipulate the motion of a mass.
Conservation of Momentum: This principle states that the total momentum of a closed system remains constant if no external forces act on it. When redirecting motion or manipulating a mass in motion, conservation of momentum can be important to consider, as changing the direction or speed of an object will affect its momentum.
Friction: Friction is the force that opposes the motion of one surface as it moves across another surface. When redirecting motion, friction can either help or hinder the process, depending on how it is utilized.
Centripetal Force: This force is directed toward the center of a circular path and is responsible for keeping an object moving in a curved path. It is essential for understanding how to manipulate the motion of objects in circular or rotational motion.
Fluid Dynamics: This field of physics deals with the motion of fluids (liquids and gases) and how they interact with solid objects. Understanding fluid dynamics is crucial for manipulating the motion of fluids, such as redirecting the flow of water through pipes or channels.
Mechanical Engineering Principles: Concepts such as levers, pulleys, gears, and inclined planes are often used to manipulate the motion of masses in various mechanical systems. These principles enable engineers to design mechanisms that can redirect motion efficiently.
Control Systems: In modern engineering, control systems are used to manipulate and regulate the motion of masses in real-time. These systems often involve sensors, actuators, and feedback mechanisms to achieve precise control over motion.
Me: Can you sum it up in one concept?
ChatGPT: The concept that encompasses redirecting motion and manipulating a mass in motion is "
kinematics and dynamics."
Kinematics deals with the motion of objects without considering the forces that cause the motion, focusing on variables like position, velocity, and acceleration. Dynamics, on the other hand, involves the study of the forces that cause motion and how they affect the motion of objects.
Together, kinematics and dynamics cover the principles and terms related to redirecting motion and manipulating masses in motion, encompassing concepts such as Newton's laws, conservation of momentum, friction, centripetal force, fluid dynamics, and mechanical engineering principles.
... So
"Kinematics and dynamics" Do you agree?
