When a book is moved from a higher shelf to a lower shelf what changes?
Gravitational potential energy
What form of stored energy does a book have while it is still on a high shelf?
How does a book on a higher shelf have more potential energy than a book on the lower shelf
Is t true the kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no
Is a shelf a plural?
Shelf.
Is the shelf in a hatch back a partial shelf or a parcel shelf?
The shelf in a hatch back is a partial shelf. A parcel is a package.
What is the potential energy of a 5 kg object sitting on a shelf 3 m high?
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
A statue has a mass of 14 kg on a shelf it sits 2m from the fround what is the gravatational potential energy?
The statue has 274.4 joules of gravatational potential energyrelative to the fround.
When a book is moved from a higher shelf to a lower shelf what changes?
Gravitational potential energy
Is Book on a high shelf chemical or potential energy?
Potential energy.
Can an object have energy when it is at rest?
Sure. When a 6-kg bowling ball is resting on a shelf that's 2 meters off the floor, it has 12 joules of gravitational potential energy referenced to the floor.
What is the definition of pontential energy?
Potential energy takes many different definitions, but the most common is due to gravity. Say move a book from the floor to a shelf that is one meter above the ground. The book has a mass of 2 kilograms. While the book is on the floor, it has zero potential energy. Since potential energy is defined as the height times the mass times the gravitational constant, and height is equal to zero at that point, there is no potential energy. But when it is moved to one meter high, the math goes as follows: 1 meter X 2 kilograms X 9.8 meters per second squared(The gravitaional Constant) = 19.6 Joules(The unit of 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.
Why does a book on a high shelf have more potential energy than on a low shelf?
Since potential energy equals mgh. When h, height increases potential energy also increases. If h is 0 then p.e is 0/
A trophy sitting on a shelf demonstrates energy?
potential
When an object is moved from the bottom shelf to the top shelf its gravitational potential energy has?
Increased
How can you the amount of potential energy in a book sitting on a bookshelf?
Place it on a higher shelf. If it has to stay on the same shelf, then its potential energy can only be increased by adding some pages to it.
What is the gravitational potential energy of a microscope with a mass of 0.5 kg sitting on a shelf 1 m from the floor?
Gravitational potential energy is the product of the force required to lift the mass and the height. For a mass of 0.5 kg, the force attracting it to the earth is 0.5 x 9.81 Newtons. (9.81 is the acceleration of a body in freefall, in units of meters/sec2.) As in this case the mass is raised 1 meter, its energy is 0.5 x 9.81 x 1 = 4.905 Joules.
