If you pull or push your muscles get stretched and gives discomfort. Sometimes muscle fibres snap in which case you get a lot of discomfort
This phenomenon is controlled by gravitational pull. Large objects tend to have a large gravitational pull. Smaller objects are pulled in by large objects. The reason why planets are a steady distance from the sun is because they have a perfect amount of inward and outward pull.
The gravitational pull between two objects depends on the mass of those objects and on their distance from one another. A large building isn't nearly large enough to create the gravitational pull to draw you towards it.
Objects of greater mass have more gravitational pull.
why does it hurt to pull your hair but not cut it?
Muscles pull. They have the capability of either contracting, or relaxing. They get longer when they relax but they do not exert any force by getting longer, since they are very flexible objects, not stiff rods. They only exert force when they contract, and the force they exert can be described as pulling. Muscles work in pairs, so that a joint can both bend and unbend, depending upon which muscle is pulling on it.
The earth's pull on objects is the force of gravity.
from the earth's strong gravitational pull, when something is so large it has a gravitational pull other objects are able to orbit it
all of them, muscles can only contract and relax
Gravitational pull is only noticeable for large objects, stars, planets, moons. Smaller objects just don't have enough mass to make much difference.
Objects orbit because planets, stars, and other large objects in space have their own gravitational pull. If it gets close enough, it will be pulled toward the object with a gravitational pull. If it is at the edge of its gravitational pull field, it will be pulled, but not directly at it and instead increase the speed it is moving at
All objects, big and small, exert gravitational pull. The moon, being very large, produces a large enough pull to affect the nearby Earth. The Earth also has a gravitational pull which holds the moon in orbit around us and keeps everyone on the ground.
