How can GRAVITY be so strong to hold planets in place, yet be weak enough 4 a plant 2 grow against it?

Answer 1

Gravity is one of the weakest forces in the future, but if you put enough of it together, as in by the mass the size of a sun, it can control planets.

Answer 2

There are four fundamental forces in our universe: strong and weak atomic forces, electromagnetic, and gravity. Of the four, gravity is the weakest. To prove that point, throw a tomato onto a sidewalk off a twenty story building.

What will happen to the tomato when it reaches the sidewalk? Will it go through the cement or will it splat and splatter all over the nearby pedestrians?

The correct answer demonstrates that gravity is weaker than the electromagnetic forces that surround the atoms in the sidewalk's atoms. If it were stronger, the pedestrians would not have ended up with tomato sauce all over their Brooks Brothers suits.

As most answerers correctly stated, gravity holds the planets in place because the sources of gravity are generally quite massive.

Answer 3

Because its governed by Newton's laws were Fg = GM1M2/R^2. Do a websearch to find out exactly what each G is.

But basically it depends on the product of the masses of the two bodies and the inverse of the square of the distance. Planets have huge masses so they generate a lot of gravity, a plant doesnt

Answer 4

It is important to know that the gravitational force is not a constant. F = mg is a simplified formula, for low Secondary school, which takes g as relative to Earth (hence 9.81 m/s2).

In reality, Gravitational force, F = GMm/r^2
where G = Gravitation constant, M, m = masses (e.g. Earth and plant or Sun and a planet), r = distance between them.

As the masses of both the Sun and the Earth are huge and so is the Gravitation constant, so the force can be quite big despite the large distances between the two.

Answer 5

the easy answer is this: gravity is in basic terms not that good. The gravitational charm between 2 large (large meaning "gadgets which have mass") is measured by employing this formula: F = -G * m[a million] * m[2] / r^2 m[a million] = mass of first merchandise m[2] = mass of second merchandise r = distance between the centers of each and every merchandise's mass G = gravitational consistent of the universe the reason gravity is adequate to carry us to the earth is effortless: compared to us, the earth is monstrously huge. I recommend, the actual undeniable reality that you'll be able to leap is info adequate that gravity isn't all that good. you're efficiently overcoming the stress of gravity it fairly is preserving you to the exterior of the planet whenever you do leap. might want to you be in a position to leap more effective on Everest as compared to how intense you would possibly want to leap contained in the mariana's trench? certain. in spite of the undeniable fact that the adaptation is amazingly small. you also weigh a lot less on Everest than what you would possibly want to weigh contained in the bottom of the mariana's trench.

Answer 6

The force of gravity is weak when compared to each atom emanating gravitons, but when a person determines the total number of atoms emanating gravitons the value becomes great in total number. It is similar to a hurricane. The wind is a friendly thing to mankind. We fly kites within it, and enjoy it when it softly blows about us, but this "mild mannered" entity is able to be a monster when condensed.

Our sun expends 665 lbs/sec in order to keep the planets in place. Our planet expends 0.00444 kg/sec. This gravity thing is not free. What makes it so special is the efficiency of the kind of energy used.

Answer 7

gravity doesnt hold planets in place, planets move, you get gravity ON planets - not in space, depending on what planet you go to - depends on how much gravity there is. Gravity doesnt stop plants from growing - it holds the seed in place. Plants go up to the light. We grow up - gravity doesn't stop us.

Answer 8

mass and distance are completely different and with distance the force reduces as the inverse of the square of the distance-so although mass is large force on planet is 'small' but significant.With a plant the mass of plant is small so force of gravity is 'small' and it gets energy for itself to grow from sunlight.

Answer 9

Because planets are HUGE and weight billions and billions of tonnes.

Answer 10

Its all a question of mass
