Gravity is a constant force in the world. Throughout this process, it’s always pulling down on every object that has mass. There are other forces at work during this process, but gravity is what keeps everything in place and prevents them from floating away!

A book’s weight causes a force of attraction to the earth. This means that if you were holding it on your finger right now, it would be pulled down by the Earth’s gravitational field and wouldn’t go anywhere. Similar principles apply when an object falls towards a surface – once again there is a force being exerted downwards thanks to our planet’s mass pulling things downward as they fall.
The amount of time something spends with space also affects its trajectory upon hitting the ground because it will have lost some kinetic energy during this process which causes objects to drop faster than they normally would had they only fallen.

Gravity is a force that pulls anything with mass towards any other object with mass but not all forces are equal: an object’s weight and distance from Earth determine its acceleration due to gravity, while at sea level it feels like we’re being pulled down by about 32 feet per second squared! This means you can’t jump as high on earth as you can on the moon even though both planets’ gravitational fields pull things downwards equally – your body has more inertia here thanks to Earth’s atmosphere and heavier air
and so you have to push yourself off the ground just a little harder.
during this process, how much work does gravity do?
when objects are being pulled towards each other by gravitational forces, energy is transferred between them according to the law of conservation of energy: for every action there’s an equal and opposite reaction. This means that while things will start out with different amounts of kinetic energy – depending on their weight or distance from Earth – they’ll all end up with the same amount before long because some goes into heating air resistance as it falls (which slows down its descent) while others collide with walls or whatever else happens to be in your way! In fact during this process, kinetic energy transfer due to collisions is the dominant force.
since gravity does not work in a vacuum, during this process how much work does it do on an object with no air resistance?
as would be expected, once all these forces are accounted for (kinetic energy transfer due to collisions is the dominant force) then any change in height that occurs because of gravitational effects will have been balanced perfectly by its opposite – meaning there’s nothing left over and so after falling from rest at some height h, weight = mass * g * h / 1000000000. In fact during this process, if you were able to measure one kilogram of mass instead of just weighing a book downscale or something like that while keeping track of exactly how many joules are transferred to the book during this process, you would find that it’s precisely zero.
in other words (…)
What is gravity?
Gravity is a force of attraction between objects with mass or density and their proximity to one another on Earth’s surface which is most responsible for the orbits of satellites around Earth as well as keeping humans firmly planted to its ground. The strength of gravitational pull varies depending upon altitude: About half way up Mount Everest, there are about 40 percent less gravitational forces than at sea level because your weight decreases due to decreased air pressure; every km (or mile) gained reduces gravitational pull by 90%*. It’s no wonder our astronauts need special equipment just so they don’t float away when they are on the moon.
The gravitational pull of Earth is what keeps you firmly planted to its surface, but during this process you can find that it’s precisely zero. This is because our experiment looks at a book being raised from one point in space and not lifted off the ground—in other words, when we raise the book up by an inch using two fingers while holding three points on its spine with one hand each, there’s no movement of mass or any push towards gravity so for all intents and purposes gravity does nothing whatsoever to change things during this process.
So why? Let’s take another look: It could be that during this process gravity doesn’t do anything
