The formula for force is Force= Mass x Acceleration. Therefore, you have to use a greater force to move the refrigerator because it has a greater mass than the book.
how does moving a fulcrum on a lever change the amount of force needed to move an object
force-meterfriction
No, work is related to energy, not to force.
It takes 160J/8m = 20N Newtons force to do the job.
A force is needed to move an object.

The main of force needed tio move an object is the objects mass, f= ma.

A force. Such a force must be stronger than any frictional forces.
it measures how much force is needed to to move it
