Introduction:
Exercise: it is a set of rules involving physical strength and skills, and it is also a behavioral activity constrained by habits, which is usually competitive.
There is no object that does not move, and there is no movement that can leave the object. Movement is conservative, that is, it can neither be created nor destroyed, but its concrete forms are diverse and can be transformed into each other, and the total amount of movement remains unchanged during the transformation.
In geometry, the motion of a rigid body is described as the mapping from a plane to itself, and the distance between any two points A and B is the same as the distance between their images A' = m (a) and B' = m (b). In philosophy, motion is defined as the linear migration of things in time and space.
