When ball is in the hand, it possesses internal energy. We give it kinetic energy when we throw it up and its kinetic energy decreases as it gains height.The kinetic energy turns to gravitational potential energy which reaches its maximum when it reaches its highest point. At that point the ball stops and then it falls.Its gravitational energy turns to kinetic energy as it falls. When it falls, its some energy turns to heat energy.When the balls hits the ground sound energy is produced and heat is given. The final energy which the body possesses is internal energy.

When it moves it has kinetic energy. And when it is above the chosen reference level (for example, above ground level), it has potential energy. A common practical situation is that an object falls down. When it starts falling, it has only potential energy; when it reaches ground level, it has only kinetic energy. At any point in between it has both.
It becomes a tornado, obviously.
In the case of a falling object, the instant before the object hits the ground. U = KE + PE; PE=-KE . Inversely, the object has the highest potential energy (lowest kinetic energy) at the starting point of the fall.
If a cat that has a mass of 4.50 kilograms sits on a ledge that is 0.800 meters above ground and it jumps down to the ground, it will have a specific amount of kinetic energy just as it reaches the ground. In this instance, the answer would be 35.3J.
Yes, a falling object has only potential energy at its highest point at rest. The same object will also have all kinetic energy and no potential energy the instant just before striking the ground at its highest velocity at ground level.
When a mass reaches the ground it will have a lot of potential energy installed inside. at the moment of hit all the potential energy is transformed into kinetic one. According to the type of the object the kinetic energy will act. if elastic it will jump up the same distance it fell (if free fall). .....
That is the point when it has the highest speed.

When it is lowest - that's when you just threw it, or when it falls back to the ground.
yes , the electron in the ground state of the hydrogen atom will absorb a photon of energy 13.6ev but not greater than 13.6 ev . because 13.6 ev is the energy which excites the hydrogen atom
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
