Gravity
One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

What is the vertical velocity to reach 500 meter height?
If you mean that you throw the ball or the rock vertically and it gets no more boost
after that, then the required vertical launch speed is 99 meters per second.
Check:
-- Time for speed to dwindle to zero is 99/9.8 seconds .
-- Average speed during that time is 99/2 .
-- Distance = (average speed) x (time) = (99/2) x (99/9.8) = 500.051 meters. Close enough!
What is the graavitaional force between a mass of 120kg and 100kg that are 3 meters apart?
The gravitational force between two masses is
F = G M1 M2/R2
'F' = the force
'G' = the universal gravitational constant
'M1' = the mass of one mass
'M2' = the mass of the other mass
'R' = the distance between the centers of mass of the two masses
In SI units, G = 6.672 x 10-11 Newton-meter2 per kilogram2
F = (6.672 x 10-11) x (120) x (100) / 9 = 8.896 x 10-8 Newton
That's about 0.000 000 32 ounce of force.
Why we don't feel gravitational force?
We do feel gravitational force if that force is not nullified by another force. But for an equal supporting force, we will be moving toward the center of earth and in that case, we will feel the gravitational force.
While lifting an object up , we feel the gravitational force.
==============================
Another thought:
We don't feel anything that is constant and never-changing.
We only feel things when they change.
Another example is: Velocity, or speed and direction of motion.
You can relax quite peacefully, and even nod off, in a passenger jet
cruising at 500 miles per hour, 7 miles above the ground. You're
reminded of your situation only when the aircraft turns, speeds up,
or slows down. (And not even so much in a bank and turn if they're
well coordinated.)
Another example: A modern, high-speed elevator (a lift).
You feel little or nothing during the high-speed 'cruise' portion
of the journey, but you become aware of the motion during the
acceleration phases, at the beginning and end of a long transfer.
This proverb likely means that when someone's pride and ego are not desired or welcome, the natural consequence will be a swift and inevitable fall from grace or downfall, similar to how objects are quickly pulled down by the force of gravity. It serves as a warning against arrogance and self-centered behavior.
Assuming that it's flown well, the terminal velocity is just about the stall speed of the aircraft - between 80 and 150 mph.
If it's just falling out of the sky then it may exceed mach (aprox 750 mph).
F = G M1 M2/R2
F = force of gravity between two masses (vector)
G = universal gravitational constant
M1 = mass of one of the two masses
M2 = mass of the other mass
R = distance between the two masses' centers of mass (vector)
Does mars have a strong gravitational force?
The acceleration of gravity on the surface of Mars, and therefore the weight
of objects located there, is about 38% of the corresponding number on the
surface of the Earth, and about 2.3 times the corresponding number on the
surface of the Moon. You're free to describe those numbers using any slippery
ambiguous adjectives you like.
Is there such thing as gravity falls in Oregon?
No, "Gravity Falls" is a fictional town featured in the animated television series of the same name created by Alex Hirsch. The show is not based on a real town in Oregon, although it is inspired by the Pacific Northwest region.
How do you get the battery in gravity fall mystery shack game?
To get the battery in the Gravity Falls Mystery Shack game, you need to go to Grunkle Stan's office and interact with the radio. This will trigger a mini-game where you need to match the symbols on the radio with the symbols on the screen. Once you complete the mini-game, you will receive the battery.
How to make gravity inTO ENERGY?
It's done every day, in hundreds of places around the world, and is a major source
of electrical energy in the US.
==> Use falling water to turn electric generators, as is done at Hoover Dam, Niagara Falls, etc.
The gravitational potential energy stored in the water at higher elevation changes
to kinetic energy as the water drops to lower elevation, and some of the kinetic
energy is robbed and used to turn the generators.
Who plays Seuss on Gravity Falls?
Alex Hirsch the creator of Gravity Falls plays Soos and Grunkle Stan.
Gravity is proportional to the mass and inversely proportional to the square of the distance of the centre of the body or bodies.
As the shuttle orbits at a comparatively low altitude and the mass remains constant the force diminishes only slightly. Being in free-fall does not mean there is no gravity.
Why each morning gravity around the bed is ten time stronger?
Gravity around the bed doesn't actually change in the morning; it's consistent throughout the day. However, when you wake up, your body is more aware of its weight and the force of gravity pulling you down, giving the sensation of gravity feeling stronger. This feeling is due to your body's adjustment from a restful state to an active one.
What is the effect of gravity on the falling object?
It is gravity that will be acting on the object as always with everything on Earth, and air resistance will also be present as this opposes the direction of movement.
Are acceleration due to gravity on small stone and big stone equal?
Yes, the acceleration due to gravity on both small and big stones is equal because it depends only on the mass of the Earth and the distance from its center. The mass of the stone does not affect the acceleration due to gravity.
How old are Dipper and Mabel from Gravity Falls?
Well in the episode where they sneak out with Wendy to the store at the end Dipper tells them he's really 12 and not 13 and Mabel and Dipper are twins so Mabel is 12
What would happen to a hot air balloon if the uplift and gravity forces were the same?
If the uplift and gravity forces were the same on a hot air balloon, it would remain at a constant altitude. The balloon would neither ascend nor descend but would instead float in a stable position in the atmosphere.
Because here on Earth, in the 'laboratory' where you must make all of your observations,
everything you see falling must fall through air. The presence of air has a substantial
effect on what you observe.
If you could do the experiments without air, and have nothing but gravity affect your
falling objects, you would see a feather and a truck fall with the same acceleration,
reach the bottom at the same time, and hit the ground with the same speed.
How does anti-gravity propulsion systems work?
Anti-gravity propulsion systems are hypothetical and not currently proven to exist. The concept involves the manipulation of gravitational forces to create thrust without the need for conventional propulsion systems. The theoretical basis for such technology often involves ideas from speculative physics, such as wormholes or negative matter.
How do you calculate force of dropped object?
The simple formula discovered by Sir Isaac Newton, F=MA (or Force=Mass x Acceleration) shows the answer to this question.
Say the mass of the object which you are dropping is 10 kg, (Mass is measured in grams), and the acceleration is 50 meters per second, then the force would be 500,000 joules (kilo means 1,000 so the mass of the object is 10,000 grams).
To get the acceleration of the object, (assuming you are on earth) you can use the formula 9.8 meters per second per second. This formula means that the speed is changing 9.8 meters every second. So after one second, it would be moving at 9.8 meters per second (9.8 x 1), after two seconds, it would be moving 19.6 meters per second (9.8 x 2), after 3 seconds it would be moving 29.4 meters per second (9.8 x 3), and so on.
So with these formulas, you can combine them to make it 9.8 x t x m= f (9.8 x time (in seconds) x mass (in grams)= force). So if you had dropped something 3 seconds ago, and it's mass is 500 grams, than your answer is 14,700 joules (9.8 x 3 x 500).
Which balances is affected by the local force of gravity is it beam or analytical or spring balance?
The spring balance is affected by the local force of gravity. It measures the force applied to an object based on the extension of a spring, which changes due to the gravitational force acting on the object. Beam and analytical balances operate based on comparing weights and are not affected by the force of gravity.
Center of gravity = center of mass, for most practical purposes. Mainly, the center of mass is the place where you imagine the mass to be concentrated. However, as a result, you can also consider inertia and weight to be concentrated at the center of mass.
What is the product of specific gravity and aniline number of oil?
The product of specific gravity and aniline number of oil gives an indication of the oil's asphaltene content and tends to correlate with its viscosity and density properties. This value is often used in the petroleum industry to assess the quality and behavior of oils in various applications.
Does gravity affect all objects in the same way?
Yes, according to Newton's law of universal gravitation, gravity affects all objects in the same way regardless of their mass. However, the force of gravity acting on an object depends on its mass and the distance from the source of the gravitational field.
