but yet you feel a pull from the earth?

Come on, you can't feel the gravity from a bus. What you feel are effects from the air flowing around the moving bus. The issue is just (as pointed out in the earlier answer) that the coupling constant of gravity is so small it is noticable only for large masses.

The gravitational field strength is dependent on the mass. The mass of the earth is huge. The mass of a car is tiny in comparison. There is in fact a gravitational pull from the car, but it is much too miniscule for you to be able to feel it. The smallest thing the gravity of which you can easily measure is probably a mountain. A mountain is large enough that its gravity will measurably deflect a pendulum hung nearby.

Have you ever stood on a street corner, and a bus went by? You can feel the pull as it goes by (if its going fast enough). It's not a huge pull, but its still happening. It's not a car, but I think you get the idea.

because rejection is the hardest Emotion to attend to. men can get quite violent, females can bypass off into the deep end! It hurts plenty, and a lot of those issues make you freeze up interior because you purely don't have the arrogance it takes to confront your own emotions up the front and own. you're baring your soul to this man or woman and letting your self in for a painful adventure, likely? I advise what are you settling for? a minimum of now you get to seek suggestion from him yet might want to you nonetheless search for suggestion from him if he rejects you? And today that feeling of attending to seek suggestion from him feels truly good, or maybe that although truly small at the same time as taken away will harm plenty. So both tell him instantly out, or write him a short letter and then get his answer and recognize once and for all, or purely settle for being acquaintances and recuperate from it, distinctly in case you imagine that is one sided. ask your self what has he surely performed to make you sense that he feels an similar as you do? reality time is a scary time, yet I continually discover that is extra effective to gently bypass in and say the way you sense and gently watch for his reply. If he says sure, you bypass from there. yet when he delays or stalls or says out excellent NO, then ask no matter if that is okay for you 2 to stay acquaintances? a minimum of from this element you could bypass on. today all you're doing is pushing aside the reality.

Compare the size of the planet earth to the size and mass of a car. That should give you some hint.
