Hi!
1.When the football is initially thrown the ball starts with the max kinetic and over the time it loses the kinetic and gains the potential until the kinetic loses all of its energy and is at the maximum height and as it starts falling then the foot ball gains kinetic , it goes back to the max kinetic if it is level ground and loses potential.

2. I believe is called mechanical energy or total energy.

Hope it helps and have a wonderful day!

The combined energy is called total energy. It is the sum of kinetic and potential energy.

What is kinetic energy?

The energy of the body by the virtue of its motion is known as the kinetic energy of the body. It is defined as the product of half of mass and square of the velocity.

According to the law of conservation of energy, total energy is defined as the sum of kinetic energy and potential energy.

Total energy = kinetic energy + potential energy

Also, the energy can not be created nor destroyed and can be transferred from one form to another form.

Hence the combined energy is called total energy. It is the sum of kinetic and potential energy.
