What happens to objects on earth when they are dropped?
When an object is released on earth (so it is free to fall), there are two forces that take hold. Gravity and Buoyancy. Gravity, of course, is what pulls matter to matter, and pulls us, and everything else towards the ground here on earth. Buoyancy is what makes things float. If the Buoyancy forces is stronger then the force of gravity, then the object will float away, at least until the buoyancy force levels out with the gravity force. Examples of buoyancy overpowering gravity is like a helium balloon floating away, or a boat floating on the water (gravity pulls the boat down, but the buoyancy over the water allows it to float).
What is gravity's role in the expansion of the Universe?
It was believed for quite a while that gravity would slow the expansion of the Universe down. But it is now known that the Universe is expanding faster and faster (apparently it tends towards an exponential growth), so there must be something else, that is pushing the Universe apart, more strongly than gravity can it together. This "something" is called "dark energy".
What is something that orbits something else?
A satellite.
Why does Earth have gravity and how does it affect the objects on its surface?
Earth has gravity because of its mass, which creates a force that pulls objects towards its center. This force affects objects on the surface by keeping them grounded and causing them to fall towards the ground when released. Gravity also determines the weight of objects on Earth, as it pulls them towards the center of the planet.
What are the two forces that keep the planets to its orbits keep them falling off in space?
The two forces are gravity, which pulls the planets toward the sun, and the planets' inertia, which makes them move forward. Gravity provides the centripetal force that keeps the planets in orbit around the sun.
Why does electrical wirings sag?
The simple answer is, "Gravity". Gravity pulls the wires down just as it pulls everything else down. The wires can only be pulled with a maximum tension, and all the while gravity is pulling down.
Why doesn't our air get pulled out into space?
Gravity pulls the air down toward the ground, just like it pulls down everything else.
What pulls the earth and moon into a revolution around the sun?
The sun's gravity - just as it pulls everything else in our solar system into orbit around itself.
What cause planets to orbit the sun?
i know only one and it's a good one, the sun's gravity pulls the planets from flying some where else EDIT: Gravity pulls objects together and angular momentum makes sure planets orbit
Does the moon do anything else but brighten up the sky?
Yes. The moon's gravity pulls on the oceans in order to make tides and waves.
What metric unit is a can measured in?
The answer depends onwhether you want to measure the can itself, or its contents;whether you wish to measure its mass or volume (or something else).The answer depends on whether you want to measure the can itself, or its contents;whether you wish to measure its mass or volume (or something else).The answer depends on whether you want to measure the can itself, or its contents;whether you wish to measure its mass or volume (or something else).The answer depends on whether you want to measure the can itself, or its contents;whether you wish to measure its mass or volume (or something else).
Why don't we fall off the Earth?
We don't fall off the Earth because of gravity. Gravity is the force that pulls objects towards the center of the Earth, keeping us and everything else on the surface.
What effect does gravity have on a chair?
Gravity pulls the chair downward, causing it to stay grounded and not float away. It also affects the weight of the chair, as the force of gravity acting on the chair creates the sensation of weight when someone sits on it.
What are items measured in grams?
they can measure a gram for patatoes or something else.
What items can be measured in grams?
they can measure a gram fo patatoes or something else
Objects can be measure in centimeter?
you can measure anything in centimeters but most things would be really big and you would want to measure them with something else
Why don't we fall if the Earth is round?
We don't fall off the Earth because of gravity. Gravity is a force that pulls everything towards the center of the Earth, keeping us and everything else on the surface. The Earth's round shape allows gravity to act evenly in all directions, keeping us grounded.
