If it is initially at twice the height, it will have twice the potential energy (compared to the ground level); therefore, when it falls down, it will also have twice the kinetic energy (assuming air resistance can be ignored).
When the rock is dropped, it loses potential energy as it falls due to gravity. This potential energy is converted into kinetic energy, increasing the rock's speed. When the rock strikes the ground, all its potential energy is converted into sound and heat energy upon impact.
When an object is lifted 6 feet off the ground, its potential energy is a certain value based on its height and mass. If the same object is then lifted 12 feet off the ground, its potential energy will be doubled compared to when it was lifted 6 feet. This is because potential energy is directly proportional to the height to which the object is lifted.
An object at rest on the ground has 0 Joules of gravitational potential energy because potential energy is calculated relative to a reference point, typically a certain height above the ground. When the object is on the ground, the height is considered to be zero, so there is no potential energy stored in the object relative to that reference point.
Potential energy is converted to kinetic energy as the object gains speed. A small amount of that energy is converted in heat by air resistance and the remaining kinetic energy is normally converted to heat when it strikes the ground. Some energy may be converted into other forms of energy depending on impact speed.
When a kid falls out of a tree, the energy given off is kinetic energy in the form of motion as the child falls towards the ground. This kinetic energy is then transferred to other forms of energy upon impact, such as sound and potential energy from the child's position above the ground.
it does not have enough energy to reach the ground
Lightning strikes occur when electrical charges build up in clouds and on the ground. When the difference in charges becomes strong enough, a channel of ionized air forms, creating a path for the electrical discharge to travel. The lightning bolt then strikes from the cloud to the ground or between clouds, releasing a powerful burst of energy in the form of light and heat.
There are three main types of lightning strikes: cloud-to-ground strikes, intra-cloud strikes, and cloud-to-cloud strikes. Cloud-to-ground strikes are the most common and well-known type, where lightning extends from the cloud to the ground. Intra-cloud strikes occur within the cloud itself, and cloud-to-cloud strikes happen between different clouds.
When the rock is dropped, it loses potential energy as it falls due to gravity. This potential energy is converted into kinetic energy, increasing the rock's speed. When the rock strikes the ground, all its potential energy is converted into sound and heat energy upon impact.
Most of the potential energy will be converted to thermal energy in this case.

When an object is lifted 6 feet off the ground, its potential energy is a certain value based on its height and mass. If the same object is then lifted 12 feet off the ground, its potential energy will be doubled compared to when it was lifted 6 feet. This is because potential energy is directly proportional to the height to which the object is lifted.

When lightning strikes a lightning rod, the last place the charges flow is into the ground through the metal rod, which provides a safe path for the electrical current. This helps protect the building from damage by directing the energy away from the structure and into the ground.
