What else can I help you with?
When a book falls from a shelf to the ground without anyone pushing on it no work is done on the book plus?
false
What would the energy changes be if a book falling off a shelf and hitting the ground?
When a book falls off a shelf and hits the ground, its potential energy is converted to kinetic energy as it falls. When it hits the ground, some of the kinetic energy is converted into sound and heat energy due to the impact.
When an electron falls back to its ground state how much energy is released?
It releases the same amount of energy that it absorbed when it was excited to a higher energy state.
When a book falls from the shelf to the ground without anyone pushing on it no work is done on the book true or false?
True. Work is defined as the product of force and displacement in the direction of the force. Since there is no force acting on the book as it falls, no work is done on the book.
When a book falls from a shelf to the ground without anyone pushing on it no work is done on the book.?
false
What type of energy does a book have if it is on the edge of a desk?
The book on the edge of the desk has potential energy due to its position relative to the ground. If the book falls, this potential energy will be converted into kinetic energy as it moves towards the ground.
What happens to water when it falls on cemented ground?
when water falls on a cemented ground the cemented ground can't absorve water much and the water flows away.
Does rain release or consume energy?
Rain releases energy through the process of condensation when water vapor in the atmosphere cools and forms into droplets, releasing latent heat. This energy is then released as the rain falls to the ground.
What happens an object falls?
It falls, accelerating constantly until it hits the ground.
What are the two forces that act on a dropped book as it falls to the floor?
The two forces that act on a dropped book as it falls to the floor are gravity, which pulls the book downward, and air resistance, which pushes against the book as it falls.
When a book falls from a shelf to the ground without anyone pushing it Is work is being done on the book?
Work is being done by the force of gravity. When the book falls to the floor, there's a force on it, and the force keeps acting on it as it covers the distance. A force acting through a distance is the definition of work. Maybe there's nobody pushing the book, but the force of gravity is pulling it down, and it's the force of gravity that does the work on the book.
What is water called when it falls to the ground?
When water falls to the ground, it is called precipitation, which can take the form of rain, snow, sleet, or hail.
