How can you increase the amount of work done when you lift a book explain

Explanation:

Using the Newton's laws, we can find the force F required for lifting the book having mass (m) and acceleration due to gravity (g) that is ;

and, the change in the position of the book that is Δx (Height)

→ Δx = Final position - Initial position

which is only the height, then the amount of work done will be calculated by :

W= mgh

m = Mass of the Body

g = Acceleration due to Gravity

h = Height of Body being displaced

you need to have a picture of the atom that way we can answer it
