Kinetic conservation - techintroduce

Definitions

The external force of all external forces and internal force in the system system is constant, and its kinetic energy is conserved.

For a single object (quality point), its synergy is zero or the number of yuan and zero, then its kinetic energy is conserved.

Depending on the dynamic canal

as the vector and f = 0, or When all force is done and f · DL = 0, the system is always constant, that is,

or write as:

and other forms.

For certain external forces and internal power, the system is unforgettable or zero, using kinetic conservation can solve certain problems.
