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!
What form of stored energy does a book have while it is still on the the high shelf?
Potential energy, specifically gravitational potential energy, since the book has the potential to fall due to gravity when it is on the high shelf.
A book at rest on a shelf has .?
A book at rest on a shelf has potential energy due to its position in the gravitational field. This potential energy is determined by the book's height above the ground and the acceleration due to gravity.
Where is gravitational potential energy found?
Gravitational potential energy is found in objects that are lifted above the ground, such as a book on a shelf or a satellite in space. It represents the energy stored in an object due to its position in a gravitational field.
Which things are stores of gravitational potential energy?
Objects at a height above the ground such as a book on a shelf, a pendulum at its peak, and water in a raised reservoir are examples of stores of gravitational potential energy.
What type of energy is book on a bookshelf?
The potential energy of a book on a bookshelf is due to its position above the ground. When the book is lifted or moved from the shelf, the potential energy decreases as it is converted into kinetic energy.
Examples of potential energy?
A stretched rubber band has elastic potential energy. Water stored behind a dam has gravitational potential energy. A compressed spring in a toy car has elastic potential energy. A book placed on a shelf has gravitational potential energy.
An example of gravitational potential energy?
Any object that is above the chosen reference level has gravitational potential energy. If your chosen reference level is the ground level, a book on the table, or you yourself if you are standing rather than lying on the floor, have potential energy.
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 could gravitational potential energy objects be?
Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. Objects like a book on a shelf, a pendulum at its highest point, or a ball held above the ground all have gravitational potential energy. This energy can be converted into kinetic energy when the object is in motion.
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?
The work done while moving a book to a higher shelf is equal to the change in potential energy of the book. As the book is lifted to a higher shelf against gravity, work is done to increase its potential energy. The potential energy of the book on the higher shelf is directly proportional to the height it is raised to.
