dude kenetic energy is stuff in motion, you mentioned before punching a wall, this hurts because hard objects are also capable of exerting a lot of force, enough force to cancel out gravity when that hard object is a giant rock the size of the earth!

Where is this safe place to go where I would be free of your ignorance and insistence that you know how things works - please tell me because I doubt its existence.

Answer my question why does the ground simply stop things from falling - if there is a force that pulls things down, simply stopping the movement with the ground, doesnt stop the force acting on it - so really we should be able to take advantage of all this kinetic energy of things just sitting on the ground- so why are we not?

You just contradicted yourself. An object that is motionless (just sitting on the ground as you put it) has 0 kinetic energy.

You are 100% on the money here (for once). A stationary object is not accelerating, but yes gravity puts a force on that object, which leads to the problem you pointed out. But alas there is the normal force (which we have mentioned before). So congratulations, you just made it from first day highschool physics to 2nd day high school physics. At the rate you are going, you might be able to solve a simple incline plane problem in a few years.

The kinetic energy of an object is (1/2)m*v^2. If the object is sitting still its velocity is 0 so its kinetic energy is 0. Wow you might be up to 3rd day high school physics now!

if you put something heavy on you you can still feel it pushing down even though it isn't moving right?

No, gravity is the contradiction - of course things on the ground have no kinetic energy - but if gravity were real - they actually would.

Do you understand the contradiction of circular logic yet?

you realize weight is massxgravity right? so any science using weight uses gravity

I realize that is what we are told, figuring out it is not true is beyond comprehension for some.

Only you know where your safe from the truth space is, or maybe you really don't and are actually as daft as you appear, or maybe your just a troll.

As for why we don't don't collapse into a denser ball of all matter on earth? You will just have to accept the fact that earth and life on earth exists and evolved to exist in an environment that the force attracting us to earth is just counter balanced enough by our body structure to not squash us and that the pressure of our atmosphere doesn't compress into pancakes as proof that it doesn't. But then how can you be certain we are not brains in vats in some sort of matrix. One baby step at a time for you card. Maybe tomorrow you will find one truth you can dare to believe in to start building a foundation of knowledge.

you can try to combine weight and mass but then why is it easier to slide something than lift it
stuff makes sense to me the way it is, mass momentum force gravity equilibrium, I can accept it might not be the case for all though, guess we won't convince each other for now
