As a ball fall downwards, it's velocity continuously increases, therefore the kinetic energy increases. As the height from the ground level decreases, the potential energy decreases. Further, the total mechanical energy remains constant throughout the motion.
The energy change that takes place as a cup falls off a table is the cup's potential energy decreases while the cup's kinetic energy increases.
Correct.
That refers to gravitational potential energy - energy related to a gravitational field. If you lift an object up, its gravitational potential energy increases; if it falls back down, its gravitational potential energy decreases.
As the object falls, it PEG or potential gravitational energy becomes kinetic energy. Before falling, it has for example 10 joules of PEG and 0 joules of Kinetic energy. As it falls, the PEG decreases and the kinetic energy increases, until it hits the ground, when all the energy is dispersed as sound, heat, etc.

For example, when an object falls, its potential energy decreases, but its kinetic energy increases, i.e., it falls faster and faster.
Kinetic energy increases and gravitational potential energy decreases.

Correct.
As the apple falls, its potential energy decreases while its kinetic energy increases, until it lands, at which point it has maximum potential energy.
Total energy is always conserved. However, it is possible to convert one type of energy to another. With some limitations, you can usually convert many types of energy to many other types. Whenever this happens, the amount of one type of energy decreases, while the amount of another energy increases. For example: if an object falls down, its potential energy decreases; its kinetic energy increases. Once it crashes to the floor, its kinetic energy is converted into heat - in other words, kinetic energy decreases, while heat energy increases.

It accelerates at the rate of 9.8m/s^2 (32.15f t/sec^2).That means its velocity increases 9.8 m/s (32.15 ft/sec)each second, until it hits the ground.

Chickens are hatched year round at a steady ratewith artificial light. In natural light, production falls of as light decreases in winter and increases toward summer.
