It is not conserved. Total energy is conserved, but specific types of energy are usually not conserved.
Not sure what you mean by "measurable" - potential energy is usually calculated, on the basis of other quantities. For example, in the case of gravitational potential energy, PE = mgh (mass x gravity x height), all of which can be measured.
The mechanical energy of the ball is conserved as it falls freely in a vacuum, meaning the sum of its potential and kinetic energy remains constant. Additionally, the total momentum of the ball is conserved during its free fall.
The sum of potential and kinetic energy is called "mechanical energy". This is NOT conserved, though - unless you consider the microscopic scale, in which case (for example) heat energy is a type of kinetic energy. In this case, the sum is simply the total energy, and the total energy IS 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.
Yes, mechanical energy is conserved as a playground swing moves. At the highest point of the swing, the potential energy is at its maximum, then as the swing moves downward, potential energy is converted to kinetic energy, and vice versa as it swings back up. Friction and air resistance cause small amounts of energy loss, but overall mechanical energy is conserved.
Yes, total energy is always conserved in a closed system, according to the law of conservation of energy. Energy can change forms within a system (e.g., potential energy to kinetic energy), but the total amount of energy remains constant.
Total energy.
Energy is conserved in an endothermic reaction because the heat absorbed becomes potential energy. This potential energy isn't lost energy, it's simply stored, instead of being used.

For any object, the summation of its potential and kinetic energies is constant.
