Is a book falling down from a high shelf kinetic or potential energy?

It's neither. It's just a piece of fruit.
While it's hanging and not moving, it has gravitational potential energy because of its position,
and food potential energy because of its chemical composition.
When it separates from the tree and moves to a different location, such as the ground or a
processing plant, it has kinetic energy because of its motion. Its chemical potential energy
doesn't change until it's processed, consumed, or rotted.

Is the food you eat potential or kinetic energy?
The food energy that can be utilized by the eater of the food is chemical potential energy. In a food fight, when the food is propelled through the air, it temporarily acquires some kinetic energy as well, which has nothing to do with its identity as food, and can't be utilized by eating the food, since it must come to rest before the eating commences. ________ All matter is made up of a combination of kinetic and potential energy. The kinetic energy that comprises your food is all the energy of motion of its molecules. The hotter your food, the faster its molecules are moving and the more kinetic energy they posess. Also, as mentioned above, if you throw your food, it will posess bulk kinetic energy. However, the majority of the energy contained within food is potential energy stored within what you could think of as unhappy chemical bonds. When you eat food, your body invests a little energy to break apart these unhappy bonds and makes new, happier bonds between the food molecules and the oxygen you breathe. When these happy bonds form, a large ammount of energy is released. Your body uses this energy for running around and having food fights.
Is a piece of candy kinetic energy or potential energy?
Candy is a lump of edible substances comprised mostly of sugar.-- The chemical energy in the sugar can be released by your body'smetabolism if you put the candy inside.-- If, instead of that, you put the candy on a high shelf, then it haspotential energy.-- Alternatively, if you throw or drop the candy, then as long as it's moving,it has kinetic energy.
Are Shelf-Mushrooms edible?
Well, it depends on WHAT SPECIES of shelf mushroom it is. The term 'shelf mushroom' is extremly genralized, usually applying to any mushroom that looks like, well, a shelf. So, for me or anyone else, u need to be MUch more specific.
If you stand on tiptoes to reach something on a high shelf you are performing at the ankle joint?
plantar flexion
Examples of fungi?
Some examples are:mushroom, mold, puffball, shelf/bracket fungus, yeast, etc.
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.
What sort of energy does a book have if it falls off a high shelf?
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.
If gravity is the only force present what is the total mechanical energy of a book falling off a shelf at a time when its potential energy is 50 J and its kinetic energy is 60 J?
110
Does a book falling from a shelf have gravitational energy?
Yes; while on the shelf it has potential energy due to gravity of mgh where m = mass and g =gravity acceleration and h is height fom floor. As it falls its potential energy is converted to kinetic energy mv squared/2 where v = velocity
What kinda of energy is a box of matches?
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.
Does a book sitting on a self have potential energy?
its physics term for the fact that it is not in motion (kinetic energy) but it is above the ground, so at any moment it could "potentially" have kinetic energy by falling to the floor.
The kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
What types of energy occur when a box is picked up and placed on a shelf?
Picking up the box gives it kinetic energy. When the box is sitting on the shelf, it has potential energy.
A vase sits on a shelf What form of energy does it possess?
Potential energy. If the vase falls, it is converted to kinetic energy. A good article is in the link below.
What are examples of conversion of kinetic to potential energy?
Lifting an object up (giving it potential energy) and dropping it (kinetic energy) onto a desk (sound and heat on impact)Potential energy can be converted to kinetic energy in various ways:Gravitational potential energy causes a static object to have potential energy at various altitudes, and when the object is in motion, it converts to kinetic energy. Elastic potential energy involves springs; when a spring is compressed the potential energy increases and when it releases, it is converted into kinetic energy. These are only two ways in which potential energy is converted into kinetic energy.Potential energy is associated with the configuration or position of the body while kinetic energy is associated with motion. The addition of these two for a body always comes out to be the same and hence makes the basis for the law of conservation of energy. The total energy (kinetic+potential) of a body is called the mechanical energy.Take for instance a simple pendulum, when it is at its amplitude (extreme left or right position), due to the negative acceleration at that point it comes to halt (therefore, potential energy is maximum). When it reaches its equilibrium position (centre or mean position), it has maximum velocity and hence maximum kinetic energy.So more motion = more kinetic energyLess motion = more potential energyaccording to law of conservation of energy,energy can neither be created nor destroyed but can be converted from one form to another,i.e.from potential to kinetic.hence when we rise a ball ,energy is transfered from us to the ball & gets stored as potential energy which on falling converts into kinetic energy.Potential energy is energy due to mass and height, while kinetic energy is energy due to mass and velocity. To convert potential energy to kinetic energy, simply let go of the object and let it fall. As is accelerates due to gravity, its potential energy will change to kinetic energy.Examples:A ball rolling down a slanted surface.Something falling off a shelf to the floor below.A spring release that opens the engine hood of a car.dropping an item from rest above the ground. think of potential energy as height and kinetic as the motion of falling.dropping an item from rest above the ground. think of potential energy as height and kinetic as the motion of falling.
Which type of energy is being converted into kinetic energy as a marble falls from a shelf?
Gravitational Potential Energy, also known as GPE.
Is a book on a shelf potential energy?
Yes it is. Because it has the POTENTIAL of falling off. Very simple physics, learned that in 6th grade.
