The energy of the body by the virtue of its motion is known as the kinetic energy of the body. The book's kinetic energy when it hits the floor will be 2J.
The energy of the body by the virtue of its motion is known as the kinetic energy of the body. It is defined as the product of half of mass and square of the velocity.
According to the law of conservation of energy, the total energy is defined as the sum of kinetic energy and potential energy.
Total energy = kinetic energy+potential energy
Also, the energy can not be created nor be destroyed can be transferred from one form to another form.
Work is also a form of energy so that total work done is transferred into the total energy but at the lowest position, the potential energy of the object is zero.
So that the total work done by the body is equal to the kinetic energy of the body.
Work = Force × distance
Kinetic energy = work = weight × height traveled
Kinetic energy =2.0×1
Kinetic energy =2.0 J
Hence the book's kinetic energy when it hits the floor will be 2J.
