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 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 happen to the kinetic energy of a falling book when the book hits the floor?
when book is dropped from the height its kinetic goes on increasing and the sudden stop to the book when it touches the ground all the kinetic energy of the book is converted into potential energy of the book which helps the book to be stable after the impact, in short when the book hits the ground kinetic energy is converted to potential energy due to law conservation of energy.
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.
If a book has fallen what energy has it change from?
A falling book exhibits a change from potential energy (rest) to kinetic energy (motion).
How much kinetic energy does a book have just it hits the floor?
Just about as much as it had potential energy before it started falling - since most of the potential energy will be converted into kinetic energy. The exact amount depends from how high it falls.
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.
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.
Book is to shelf as plate is to?
Kinetic Energy
Which form of energy is represented by a book lying on a desk which form of energy is represented by book falling off a desk?
Lying on a desk: Potential energy Falling off a desk: Kinetic Energy
