The potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.
Since the mass and acceleration due to gravity remain constant, the potential energy is directly proportional to the height of the object. Thus, the potential energy is greatest at a height of 10 meters.

The kinetic energy of an object is given by the formula KE = 0.5mv^2, where m is the mass of the object and v is the velocity of the object.
As the ball falls from a height of 10 meters, it gains speed and its velocity increases. Therefore, the kinetic energy of the ball would be greatest just above 0 meters, right before it hits the ground.

As the ball is falling, its height is decreasing. The potential energy of an object is directly proportional to its height. Therefore, as the ball's height decreases, its potential energy is also decreasing. Thus, the correct answer is "Potential energy is decreasing."

As the ball is falling, it is gaining speed and its velocity is increasing. Since the kinetic energy is directly proportional to the square of velocity, as the velocity increases, the kinetic energy also increases. Therefore, the correct answer is "Kinetic energy is increasing."

The total energy of an object is the sum of its potential energy and kinetic energy.
As the ball is falling, its potential energy is decreasing while its kinetic energy is increasing. However, the sum of these two energies remains constant, assuming no external forces or energy losses. This principle is known as the conservation of energy.
Therefore, the correct answer is "Total energy is staying the same."
