What is the gravitational potential energy of a 2 kg book on a shelf 2 m high?

Just calculate the potential energy in both cases, then subtract! The formula for gravitational potential energy is PE = mgh (mass x gravity x height). In SI units, gravity is approximately 9.8.

∙ 11y agoPlease use the formula for gravitational potential energy: PE = mgh (mass x gravity x height). Use 9.8 for gravity.
Wiki User
∙ 6y agoit is energy = mass x gravity acceleration x height = mgh. Thus energy = 2 x 9.81 x 2 = 39.24 joules

A 5 kg book falls from a shelf. If it lands with a speed of 5.7 ms from what height did it fall?
Here is one way to solve it:* Calculate the kinetic energy related to this speed. * Assume that no mechanical energy was lost; i.e., calculate the height required to get the same gravitational potential energy. That is, write the equation for gravitational potential energy, replace the numbers you know (including the energy you just calculated in the previous point), and calculate the height. Note that the result does not depend on the mass of the falling object.
When you pick up a book you use what kind of energy from your hand to the book?
When a book is picked up,its potential energy is increased. The hand picking up the book is also gaining potential energy. The energy is coming from the muscles contractions involved in picking up the book. The muscle energy is a result of processing food nutrients.
What type of energy does a battery hamburger book on a shelf a green plant a beam of sunlight a piece of radioactive metal a cup of hot cocoa have?
The answer is ((The Nature of Energy))
How do the various forms of energy differ?
Energy can either be "potential" energy or "kinetic" energy. Potential energy is energy that is stored in some system: a stretched rubber band, a book sitting on a table, or the chemical bonds in the wax of a candle. Kinetic energy is energy that is moving, and generally comes from the release of potential energy, such as letting go of the rubber band, the book falling off the table, or lighting the candle.
What is the difference between kinetic energy and potential energy?
Kinetic energy is the energy in the movement.Potential energy is stored energy, ready to be used.K.E-motion energyP.E-energy stored during displacement of springs that tend to restore to original position of springKinetic energy is the energy found in every object in motion .Gravitational Potential Energy is the enegry stored in an object because of its height. For example, the energy that water has before it goes over a waterfall. Chemical potential energy is the energy that a substance can release by undergoing a chemical reaction, for example gasoline which releases energy when it is burned. Mechanical potential energy would be the kind stored in a compressed spring. Radioactive materials such as uranium have nuclear potential energy.Kinetic energy is the energy of motion.. while something is moving.. and potential energy is the energy being stored up for the object TO move.A ball rolling has kinetic energy... when you pull back a spoon to throw food at someone, when you pull back and hold it there, it has potential energy (potential to be kinetic, that is)Potential energy is the capacity for doing work that a body possesses because of itsposition or condition. While kinetic energy is energy a body possesses because it is in motion.kinetic energy is moving energy or energy used in preforming an action.potiental energy is sitting energy or energy that is being saved up.potential- when energy is stored.kinetic- when energy is movingPotential energy is stored energy, when building up to it's highest point the energy is released as kinetic energy. For example potential energy is the energy gathered when moving slowly up an amusement park ride, when you reach the top the potential energy reaches it's limit and is realeased as kinetic energy when you rocket downwards.
When a book is moved from a higher shelf to a lower shelf what changes?
Gravitational potential energy
Does a book sitting on a shelf have gravitational potential energy?
YES!
Give an example of gravitational potential energy?
a book sitting up on a shelf. gravity can potentionally pull it down if pushed.
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.
What is the relationship between the work done while moving a book to a higher bookshelf and the potential energy that the book has on higher shelf?
Potetial energy is the energy an object has because of its position or location, or its energy of position.
Is Book on a high shelf chemical or potential energy?
Potential energy.
What energy of a book on a shelf is equal to the work done to lift the book to the shelf?
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
Can you give me an example of a potential energy?
Potential energy is energy of an object due to its location or the effect of forces which are "locked" in place. One example is a book on a shelf: it has gravitational potential energy which is realised when it falls. Another is a stretched spring whose potential energy is realised when the spring is allowed to return to its normal length.
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
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 is the relationship between the work done to lift a book to place it on a bookshelf and the potential energy of the book on the shelf?
There is no direct relationship because the potential energy of the book on the shelf is defined relative to an arbitrary base line at which the potential energy would be zero. The work done in raising the book is the increase in the potential energy of book from however much PE it had in its previous location - for example, on a lower shelf.
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.
