gravity
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
the energy in an object about to fall is potential energy then kinetic energy because when the object is not falling, it has potential energy but when it's actually falling, it has kinetic energy.
That is a trick question, but I believe it is kinetic energy.
Kinetic energy of a falling object can be calculated for a specific height at a specific point since a falling body accelerates which means that it's velocity is changing every moment. To calculate the kinetic energy of a falling body at a certain height, we should know the mass of the body and its velocity at that point.Then we can apply the following formula: K.E. of an object = 1/2(mv2)
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.

A falling object.

A falling object changes from gravitational potential to kinetic.

No. Friction with the air does with an object in free fall in the earth's atmosphere. Gravity causes a falling body to accelerate so it changes potential energy into kinetic energy.
Once the object has reached the ground, its kinetic energy is zero.

It isn't. Kinetic energy is 1/2 x mass x speed squared, so if an object has mass, and it moves, it follows that it has kinetic energy.

An object's potential energy doesn't depend on its speed. You can do anything you like with the object's speed, and it has no effect on potential energy.
