How does mass affect gravity?

How does gravity affect free falling objects?
Why does all matter have a gravitational field?
Free Falling objects are falling under the sole influence of gravity. This force causes all free-falling objects on Earth to accelerate downward towards the Earth. But what affect does object mass have on this value? The Physics Classroom explains.

A gravitational field is where a mass experiences a force. All matter has a gravitational field that attracts other objects. The more mass an object has, the greater its gravitational field...
The force of gravity exists between all objects. The closer together the objects are, the more noticeable the effect. But gravity only becomes noticeable when you have at least one very big mass...

Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein desc...
Gravity is what holds the planets in orbitaround the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light. Albert Einstein ...
Gravity is very important to us. We could not live on Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe. Gravity is what holds our world together. However, gravity isn’t the same everywhere on Earth...
Newton proposed that gravity is a force of attraction between ALL objects that have mass. And the strength of the force is proportional to the product of the masses of the two objects and inversely proportional to the distance of separation between the object's centers.
Gravity is most accurately described by the general theory of relativity, proposed by Albert Einstein in 1915, which describes gravity not as a force, but as the curvature of spacetime, caused by the uneven distribution of mass, and causing masses to move along geodesic lines.
