What energy changes occur when a falling rock hits the ground?
Kinetic Enegry
When a coin is dropped to the ground as the coin falls it loses potential energy and gains what kind of energy?
when a coin is falling it is losing kinetic energy when it lands it is gaining potential. kinetic energy is the energy of movement. potential is the energy of stillness.
When could a rock have both kinetic and potential energy?
When it moves it has kinetic energy. And when it is above the chosen reference level (for example, above ground level), it has potential energy. A common practical situation is that an object falls down. When it starts falling, it has only potential energy; when it reaches ground level, it has only kinetic energy. At any point in between it has both.
Describe a stone falling off a tabletop in terms of both kinetic energy and potential energy?
Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.
A flowerpot falls from a ledge 50 m above the ground. compare the potential and kinetic energy when it is at 25 m above the ground to its original potential and kinetic energy?
After falling 25 meters, it has less potential energy, by an amount calculated with the formula mgh (mass x gravity x height). If you ignore air resistance, the kinetic energy will increase by the same amount.
What is the kinetic energy of the free falling object that eventually stop on reaching the ground?
Once the object has reached the ground, its kinetic energy is zero.

Kinetic Enegry
What energy is a falling apple in a tree?
From gravitational potential energy to kinetic energy and if you want it until it drops onto the ground , (continue from kinetic energy) heat energy + sound energy.
How does the total energy change when when a falling rock hits the ground?
when the rock falls it gain kinetic energy when it falls.
Is a book falling from a book shelf kinetic or potential?
When a book is falling from a bookshelf, it is in a state of kinetic energy because it is in motion. Potential energy arises when the book is stationary on the shelf due to its height above the ground.

Can you have not potential energy and all kinetic energy?
Yes, a falling object has only potential energy at its highest point at rest. The same object will also have all kinetic energy and no potential energy the instant just before striking the ground at its highest velocity at ground level.
What happen to the kinetic energy of a falling book when the book hits the floor?
when book is dropped from the height its kinetic goes on increasing and the sudden stop to the book when it touches the ground all the kinetic energy of the book is converted into potential energy of the book which helps the book to be stable after the impact, in short when the book hits the ground kinetic energy is converted to potential energy due to law conservation of energy.
