The force that pulls objects to the center of the Earth is called gravity. In places like outer space, where the gravitational pull of celestial bodies may be minimal, you may not feel the typical effects of gravity.
This is a very good question! You might be fooled into thinking that the only thing we feel if we walk around is the normal force pushing upwards against our feet, but this is because we are so used to feeling the effect of gravity (because it is almost never absent) that we are not consciously aware of it. You can check this by going into a rollercoaster or a fun fare attraction where there is a drop in free fall or even on a swing. In such situations you might feel a soft tingling in your stomach as your organs adjust to being in free fall. Being in free fall actually means you are no longer feeling the effects of gravity. This might sound strange, after all you are falling because of gravity! But it is true. In fact, it is the thing that prompted Albert Einstein to formulate his theory of gravity. And since we can feel the absence of gravity (the tingling of the stomach for example) we must also be able to feel gravity (or rather acceleration). It is just that we are so used to living with gravity and free fall situations are so rare that we think we do not feel gravity.
Gravity affects velocity by changing the acceleration of an object. As an object falls, gravity accelerates it, increasing its velocity. Without gravity, an object would move at a constant velocity.
Gravity really is one of the four main forces of the Universe. gravity is an effect and not the cause of anything, no gravitation's, no gravity waves, none of it. gravity is a dynamic effect. the acceleration of the underlying for of energy focused to the center of a mass. there is no separate force called gravity, just a dynamic effect we call 'gravity'
Gravity does not effect speed of light ,so velocity is constant. Even if it effect the effect is negligible. So in short answer is 3*108ms-1 -Thunder
The most noticeable effect is the tides.
Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
Because gravity is stronger with a bigger object. The greatest effect on the gravity you undergo has to do with the immense electromagnetivity from the Earth's core. There are none of those physical factors in space.
It is really the other way round - gravity has an effect on weight. The more gravity, the more weight.
It compresses it. This is the reason why the Earth is the most dense planet in the Solar System.
You are asleep? When you walk, do you feel the ground? That's gravity.
The most important effect of gravity in hockey is that it keeps the ball on or close to the ground. For that matter it also keeps the players on the ground.
Gravity affects everything that has mass.
To get an understanding of what causes gravity you need to start by understanding what 'energy' actually is, and luckily, we can see(1) it and we can touch(2) it, however, we can also feel(3) its effect on the bottom of our feet. http://www.simplegravity.com/

No.
All matter, including air has a gravitational pull. The gravity we feel, though is not a product of Earth's atmosphere, which has a tiny mass in proportion to the planet itself. Most of the mass of Earth is rock and metal. That is the source of most of Earth's gravity.
