The total amoun of enery remains unchanged. However some of it is converted into different forms.
Gravitational Potential Energy, also known as GPE.
Potential energy. If the vase falls, it is converted to kinetic energy. A good article is in the link below.
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.
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
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.
Potential Energy If it falls, it will then be subject of gravity, so it has the potential of becoming energetic. -------------------- The bookshelf could also catch fire and the book would release energy as heat.
"Shelf" is about a girl that everyone falls for and has a gallery of hearts at her disposal.
Gravitational potential energy
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
Potetial energy is the energy an object has because of its position or location, or its energy of position.
Picking up the box gives it kinetic energy. When the box is sitting on the shelf, it has potential energy.
Whenever work is being done, energy is changing from form to another, so the shortest answer is "by doing work". As an example, If you lift a brick from the ground to a shelf, the work you do - muscle energy - is converted to potential energy in the brick. If you then push the brick off the shelf, it crashes to the ground and that potential energy changes to kinetic energy as it falls, and to sound and brick smashing energy when it hits the floor. Avoid toe breaking energies and don't try this at home.
