Want this question answered?
I have no way to know, because I was not in the room while you were doing the experiment.
Inertia is directly proportional to an objects mass. Inertia is the desire of objects to continue doing exactly what they are doing. The greater the mass the greater the inertia.
Strictly speaking, the only thing that opposes to force and slows objects in all scenarios is friction. If you are trying to move an object upwards, gravity is a downward force and as such is capable of doing opposing upwards forces and causing the object to slow down as well
Moving a force through a distance.
downward force of your body on the chair force on pen to write with

Deep question, but at the end of the day, Yes. It is true that no force is needed. Because if you put an object into space for example, it will continue what it is doing. If there was no gravity, it would just sit there.

The first law comes closest. Objects have a tendency not to change their velocity.
In the most precise sense, 'work' is defined as force acting through a distance. So ... straining to agree with something in the question ... if a force has already come along and moved through part of the distance, doing some of the required work in the process, then yes, the work already done by the force has reduced the amount of work remaining to be done. But that's a real stretch.

he/she already done it whats she/he doing

the force of the particals would prevent you from doing it.
Objects in space are always Floating and/or orbiting a larger object because of the lack of gravity in space.
