How is kinetic energy lost on impact to the ground?

I think this is because of no movement...??

most warms the ground up. some is lost in radiated sound.

When an object impacts the ground, kinetic energy is primarily lost through the process of deformation and the generation of heat and sound. Let me explain step by step how kinetic energy is lost in this situation:

1. Deformation: When an object hits the ground, it undergoes deformation due to the compression forces involved. This deformation is more prominent in materials like rubber or clay, which can absorb and recover their shape to some extent. However, even rigid materials like metal still experience some degree of deformation upon impact. Deformation requires energy, and as a result, some of the object's kinetic energy is transformed into potential energy stored within the deformed structure.

2. Heat: Whenever there is a collision, especially between solid objects, friction is generated. Friction between the impacting object and the ground will convert some of the kinetic energy into thermal energy, also known as heat. This heat is dissipated into the surroundings, causing a loss of kinetic energy.

3. Sound: Another form of energy dissipation upon impact is through the generation of sound waves. When an object collides with the ground, it produces vibrations that travel through the air as sound waves. The energy carried by these sound waves represents a loss of kinetic energy from the object.

It is important to note that the conservation of energy principle remains intact throughout the process. Although kinetic energy may be lost, it is transformed into other forms of energy such as potential energy, heat, and sound energy.
