Mechanical energy conservation law formula
The formula of the law of conservation of mechanical energy is k + u = constant value, which means that the total mechanical energy (sum of kinetic energy and potential energy) of the system in a closed system remains constant, that is, kinetic energy and potential energy can be converted into each other in the system, but the total mechanical energy always remains unchanged.

What is the formula of the law of conservation of mechanical energy?The formula of the law of conservation of mechanical energy is K + U = constant value, which means that the total mechanical energy (sum of kinetic energy and potential energy) of the system in a closed system remains constant, that is, kinetic energy and potential energy can be converted into each other in the system, but the total mechanical energy always remains unchanged.
What are the conditions for conservation of mechanical energy?Three conditions for the conservation of mechanical energy: 1. From the WF outside = △E machine in the functional relationship equation, it can be seen that the broader mechanical energy conservation condition should be that the work done by the force outside the system is zero; 2. When the system is not subject to external forces or all When the sum of the work done by external forces is zero, the total momentum of the system remains unchanged, which is called the law of conservation of momentum; 3. Mechanical energy is conserved when only kinetic energy and potential energy are converted into each other.
