When a book falls off a shelf and hits the ground, its potential energy is converted to kinetic energy as it falls. When it hits the ground, some of the kinetic energy is converted into sound and heat energy due to the impact.
When a falling rock hits the ground, its potential energy is converted to kinetic energy as it accelerates towards the ground. Upon impact, some of the kinetic energy is transformed into sound energy, heat energy due to friction, and deformation energy as the rock changes shape upon collision with the surface.
When a falling bag hits the floor, the potential energy of the bag due to its height above the ground is converted into kinetic energy as it falls. Upon impact with the floor, some of this kinetic energy is dissipated as sound and heat energy.
The kinetic energy of a freely falling body at ground level is equal to its potential energy at the starting height, assuming no air resistance or other external forces are acting on it. The kinetic energy is given by ( KE = \frac {1}{2} m v^2 ), where (m) is the mass of the object and (v) is its velocity just before hitting the ground.
Hitting the ground is commonly referred to as falling or landing, depending on the context in which it occurs.
When a falling stone hits the ground, its kinetic energy is mostly converted into sound energy, heat energy, and some energy used to break pieces of the ground.

You can hear the sound of the book hitting the floor and feel the vibrations through the ground or surrounding surfaces. Additionally, you may see the movement and impact of the book falling with your eyes.
When you fall and hit the ground with your elbow, the force is concentrated on a smaller area compared to hitting the ground with your back. This smaller area leads to higher pressure exerted by your elbow on impact. In contrast, hitting the ground with your back distributes the force over a larger surface area, resulting in lower pressure.
As a falling object descends, its potential energy (due to its position above the ground) is converted into kinetic energy (energy of motion). This kinetic energy increases as the object accelerates towards the ground. When the object reaches the ground, all of its potential energy is converted into kinetic energy.
No, falling rocks would typically be considered potential energy as they have the potential to do work due to their position above ground. Once they start falling, they convert potential energy to kinetic energy.

Once the object has reached the ground, its kinetic energy is zero.
