Before it falls it has gravitational potential energy. While it falls, the potential energy gets converted to kinetic energy. Part of this gets dissipated by friction - mainly converted to heat. Once it hits the ground, all the energy will be converted to heat.
No. Kinetic energy is moving energy. A book on a shelf would be considered as potential energy. Potential energy however can turn into kinetic energy and back again. The formula for potential energy is PE = m*g*h. m = mass; g = acceleration of gravity; h = height relative to where you measure it from (traditionally the ground). If the bookshelf is exceptionally tall, the book has a lot of potential energy while if it is very short, almost to the point of being on the ground, it has very little.
kinetic because i t has force of falling down
It has gravitational potential energy and kinetic energy.
A book on a shelf has potential energy.
Potential Energy
A book on a shelf has potential energy.
potential energy
Just about as much as it had potential energy before it started falling - since most of the potential energy will be converted into kinetic energy. The exact amount depends from how high it falls.
Gravitational potential energy is a type of energy that an object possesses because of where it is placed in a gravitational field. The higher the object the more energy it has, so if you had an object that was on the ground and then you put it on a high shelf then it would have more energy when it is on the shelf.
yes because is more
A box of matches on a high shelf has gravitational potential energy.A box of matches falling from the high shelf has kinetic energy.A box of matches on fire has heat, sound and light energy.A box of matches on its own has chemical potential energy.
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
How does a book on a higher shelf have more potential energy than a book on the lower shelf
Potential energy.

Since potential energy equals mgh. When h, height increases potential energy also increases. If h is 0 then p.e is 0/

First energy level bc as the electron falls from high to low it emitts energy
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
Basically, you reach for a book in the library with your hand. So i suppose the two ways are; 'standing on the floor' or 'standing on a ladder' if the book is on a high shelf.
Um, using a cup and spoon works pretty well.
