THE INNOVATION AND PRACTICE IN TEACHING THE MOMENT OF INERTIA TENSOR
摘要
Abstract
Tensors are a very important concept in theoretical physics.The inertia tensor is the first concept of tensors that students encounter in undergraduate courses.This paper at-tempts to innovate the teaching content of the inertia tensor by reorganizing the teaching con-tent of the inertia tensor of rigid bodies.It starts with calculating the angular momentum of a rigid body rotating about a fixed point,then introduces the matrix form,and finally intro-duces the concept of the inertia tensor,dyadic notation,and their calculation rules.This ap-proach helps students understand that the introduction of tensors is natural and is just a math-ematical form of problem description,but it brings convenience.Using this as a starting point,it lays a solid foundation for students'subsequent learning of theories involving tensors and also cultivates their innovative thinking.关键词
