If words are direct synonyms - the words are very interchangeable.
A sitting rock has no force, it is hard to pick up because it has weight. The fact you have have faith there is a force does not make it so. If there was a constant force being applied to all objects like gravity, we would have an infinite source of power, so go ahead and waste your life thinking about how we can convert this force you believe in, go for it.
They are synonyms to some extent, not when talking about weight in its physics definition.
The sitting rock has force, you said it yourself; weight. You can easily calculate the force applied by the air on the rock you've thrown. If that was the only force applied, you could be throwing rocks miles away. What's your explanation as to why the rock falls back to the ground so quickly?
Machines using earth's gravitational force already exist. Hydroelectric dams and tidal generators use gravity to generate electricity.

Why do we need doctors/professionals anymore when you have the power to look stuff up on WebMd.com or Wikipedia?
Because people like you can edit Wikipedia pages without knowing what they're talking about. But hey, it must be coincidence if all professionals understand gravity in a way that's different to your understanding.
