1. Inertia is the basic property of an object, which is only related to its mass.
2. The greater the inertia, the more difficult it is for an object to change its motion state.
2. Expand the connection between cattle and sports.
1. Relationship between inertia and acceleration: Newton's ratio shows that the acceleration of an object is a=F/m, that is, when subjected to the same force, the acceleration of a mass object is small, that is, it is difficult to change the motion state, which also reflects Newton's second nature.
2. The relationship between inertia and impulse: I=△P=m△V=Ft is known.
It is known that △V=Ft/m, that is, the change of mass and speed is inversely proportional, which also proves the second property of cattle uniformity.
