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.

false
the real question is, will anyone hear it?
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.
An apple falls downward due to gravity, a force that pulls objects towards the center of the Earth. This force is stronger than any force pushing the apple upwards, causing it to fall towards the ground.
By squatting and pushing then the stuff falls out of the butt
when water falls on a cemented ground the cemented ground can't absorve water much and the water flows away.
Yes, rainfall can occur without wind. Rainfall is caused by the condensation of water vapor in the atmosphere, which then falls to the ground due to gravity. While wind can impact the direction and speed at which rain falls, it is not a requirement for rain to occur.
A falling snowflake or raindrop does not accelerate as it approaches the ground because their mass doesn't change. The form is not affected throughout the fall so it is already approaching the ground at terminal velocity. Hope this helps.
It falls, accelerating constantly until it hits the ground.
Asexual reproduction occurs when a small piece of cactus breaks off, falls to the ground, and grows into a new plant without involving the fusion of gametes from two individuals. This process allows the cactus to propagate without the need for pollination or fertilization.
When water falls to the ground, it is called precipitation, which can take the form of rain, snow, sleet, or hail.
