How do you identify the situations in which conservation of mechanical energy is valid?
Conservation of mechanical energy is valid in situations where only conservative forces are acting on the system, such as gravitational or spring forces. Non-conservative forces, like friction or air resistance, can cause mechanical energy to be lost from the system, making conservation of energy invalid. Additionally, the system must be isolated from external influences for conservation of mechanical energy to hold true.

Why doesn't the principle of mechanical energy conversation hold in situations when frictional forces are present?
Frictional forces result in the conversion of mechanical energy into heat energy. This transformation leads to a loss of mechanical energy in the system, causing the principle of mechanical energy conservation to not hold true in these situations.
Is the conservation of mechanical energy likely to hold in this scenario?
In most cases, the conservation of mechanical energy is likely to hold true in this scenario.
What are the differences between Conservation law of energy and Conservation law of Mechanical energy in Physics?
The law of conservation of energy states that the total energy in the universe is a constant and will remain so for example ( x=y+z ). conservation of energy has to do with reducing the amount of energy used through reduced activity and/or increased efficiency in the performance of a particular task.
Which energy is always conserved?
Mechanical energy is always conserved in a closed system. It can exist as potential energy (stored energy) and kinetic energy (energy of motion). This conservation principle is known as the law of conservation of mechanical energy.
Explaine the law of conservation of mechanical energy?
This simply means that, as long as no mechanical energy is wasted or converted to other types of energy (and no other type of energy to mechanical energy), the total amount of mechanical energy doesn't change. Mechanical energy refers to the sum of kinetic and potential energy. Since energy losses and energy conversions do occur, this is not really a "law". In other words, the law of conservation of energy has not been known to be violated; conservation of mechanical energy is very easily violated.

Why doesn't the principle of mechanical energy conservation hold in situations when frictional forces are present?
In the case of friction, energy is wasted, i.e., mechanical energy is converted into useless energy, mainly heat.

In most cases, the conservation of mechanical energy is likely to hold true in this scenario.

What is the difference between conservation of mechanical energy and conservation of total energy?
Conservation of mechanical energy states that the sum of kinetic and potential energy remains constant in a system with only conservative forces at work. On the other hand, conservation of total energy includes all forms of energy including mechanical, thermal, chemical, etc. and states that the total energy of a system remains constant in the absence of external forces like friction or air resistance.

In situations is mechanical energy conserved?
Mechanical energy is conserved in situations where only conservative forces are present, such as gravity or spring forces. In these cases, the total mechanical energy (kinetic energy + potential energy) of a system remains constant as long as no external work is done.
