The main of force needed tio move an object is the objects mass, f= ma.
because the more force the machine puts on it the farther the object will go, therefore the less work you have to do to move the object.
. The amount of Force needed to make an object change its motion depends on the Mass of the object and the Force required
Only the object's mass.
Yes.
how does moving a fulcrum on a lever change the amount of force needed to move an object
dependant on many factors.
Other forces and the mass of the object.
Force is the only such factor.
size , shape , and speed of the object
the less force is needed.
If the mass changes then the amount of material in the object changes. This will also affect the moment of inertia and the gravitational effect of the object.
