When a projectile hits the ground, its kinetic energy is converted into other forms of energy such as sound, heat, and potential energy of the object and the ground. This is due to the principle of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another.

At the moment of impact, the projectile's kinetic energy is at its maximum, as it is moving with a high velocity. As it collides with the ground, this kinetic energy is transferred to the ground and the projectile itself. The ground absorbs some of the energy, causing it to vibrate and create sound waves. The remaining energy is used to deform the projectile and the ground, creating potential energy in the form of a compressed or displaced object.

Some of the kinetic energy may also be converted into heat due to friction between the projectile and the ground. This heat energy is dissipated into the surroundings, causing a slight increase in temperature.

In summary, the kinetic energy of a projectile is converted into potential energy and other forms of energy upon impact with the ground. This process occurs almost instantaneously and is an important factor in understanding the behavior of projectiles and the effects of their impact.
