1, Euler's equation of motion is the basic equation describing the motion of a rigid body. A rigid body means that all points of an object have the same displacement, so there is no deformation. Euler's dynamic equation is used to describe the rotational motion of rigid bodies.
2. Let's briefly introduce Euler's dynamic equation:
Euler's dynamic equation describes the mechanical principle of angular motion and swing of rigid body. They are three nonlinear differential equations, which involve the instantaneous angular velocity of rigid body and the product of matrix.
The first Euler dynamic equation describes the dynamic principle of rigid body rotating around its own X axis.
The second Euler dynamic equation describes the dynamic principle of rigid body rotating around its own Y axis.
The third Euler dynamic equation describes the dynamic principle of rigid body rotating around its own Z axis.
Introduction to Newton:
Isaac Newton (1643, 65438+1October 4-65438+March 0727, 3 1) is a British physicist, mathematician, astronomer, natural philosopher, alchemist and theologian. He has made great contributions to the development of physics and natural science and is regarded as one of the founders of modern science.
Newton made great contributions in mathematics, mechanics and optics. In mathematics, he invented calculus and some initial variational methods and applied them to mechanics; In mechanics, he put forward Newton's three laws, as well as the motion theorem (Newton's second law) and the law of universal gravitation. In optics, Newton invented and manufactured a new reflective telescope, studied the dispersion phenomenon of light, put forward the dispersion theory, and initiated modern optics.
Newton is regarded as a great natural scientist, who has made great contributions in many fields, not only to the development of modern physics and mathematics, but also to engineering, astronomy, philosophy, theology and other fields. Newton's academic achievements are rich, and his work has been widely recognized in his time and has been passed down to this day, becoming a classic in the history of science.
