How do you make spandex gravity well?
To construct the gravity well:
- Brace the hula hoop on the four supports (chair backs or similar).
- Drape the spandex cloth over the hoop.
- Slightly stretch the cloth and begin to attach the pegs in pairs.
- Keep tension on the cloth as pegs are added.
- Continue to peg the cloth, using 16 evenly spaced pegs.
Is gravity a force or fabric?
The more massive the object, the more it pulls. The amount of pull exerted by an object on the universal fabric is its gravitational force. So the apple falls to Earth because Earth has warped space-time in such a way that the apple must move toward Earth’s center.
What is the force of gravity short answer?
The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity. Objects with more mass have more gravity.
How is the force of gravity on an object?
You can calculate the force of gravity on an object using the object’s mass and this acceleration. The formula that expresses Newton’s second law is F = ma. If you use g as the acceleration, the formula for calculating the force due to gravity on a mass close to Earth’s surface becomes F = mg.
What does the fabric of a gravity well represent?
The well represents the gravitational potential field that surrounds an object.
How does gravity act like a heavy object on a stretchy fabric?
Every object exerts a gravitational force on every other object. In the spandex sheet, gravity is represented by how much the spandex stretches. Close to the large mass, there is a lot of stretching, and so there is a lot of gravity. Far away from the mass, there is less stretching, and so there is less gravity.
Is gravity a push or a pool?
As a curvature, or warping of spacetime, gravity is neither a push nor a pull. Astronauts in orbit float freely, i.e., force-free, under the influence of gravity, even though they seem to be pulled in an accelerated path around the earth.
How do you explain gravity?
Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth’s gravity is what keeps you on the ground and what causes objects to fall.
Is gravity a downward force?
gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. …
Does moon have gravity?
1.62 m/s²
Moon/Gravity
How to calculate the force of gravity sciencing?
How to Calculate Force of Gravity | Sciencing The famous force due to gravity formula is an extension of Newton’s second law, which states that a mass subjected to an outside force will experience acceleration: F = ma. The force of gravity is a special case of this, with
How does the gravity of an object depend on its size?
The gravity of an object depends on its size. To be more specific, the Gravity of an object depends on the mass of that object. It is undoubtedly the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. Relationship Between Gravity and Weight
How is gravity the most dominant force in the universe?
Basic Facts about Gravity. Gravity is the weakest of the four known fundamental forces of nature, yet it is the most dominant force. Even though it is the weakest force, Gravity holds together the entire solar systems and galaxies. The speed of freefall is consistent over the surface of the earth.
What does Albert Einstein say about gravity in space?
An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet. If another object is nearby, it is pulled into the curve. Image credit: NASA Anything that has mass also has gravity. Objects with more mass have more gravity.
