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.

When a country that is weak is shielded by a stronger the weaker is a?

User Avatar

Asked by Wiki User

When a weak country is protected by a stronger one, the weaker country is typically referred to as a client state or satellite state. This arrangement often involves the weaker country relying on the stronger one for security, economic support, or political guidance.

How is the gravity survey caried out today?

User Avatar

Asked by Vikusyabrenzovych

Gravity surveys are conducted today using highly sensitive instruments like gravimeters that measure the gravitational field of the Earth at different locations. These instruments are mounted on aircraft or vehicles to collect data across large areas quickly and accurately. The data is then processed to create maps showing variations in gravity, which can be used to understand subsurface geological features.

When two values change in opposite directions so that if one increases and the other decreases by the same amount they are said to be inversely proportional to each other?

User Avatar

Asked by Wiki User

When two values are inversely proportional, one value increases as the other decreases, keeping their product constant. In mathematical terms, this relationship can be expressed as y = k/x, where y and x are the two values and k is the constant of proportionality. Examples include the relation between speed and time to travel a certain distance, or pressure and volume of a gas at constant temperature.

Is sitting down gravity?

User Avatar

Asked by Wiki User

Sitting down is not gravity itself, but gravity is the force that pulls us toward the ground when we sit. It is the Earth's gravitational force acting on our bodies that keeps us in our seated position.

Mercury's surface gravity?

User Avatar

Asked by Wiki User

Mercury's surface gravity is about 3.7 m/s^2, which is approximately 38% of Earth's surface gravity. This means that objects on Mercury weigh less than they do on Earth due to the lower gravitational pull.

What are the disadvantages of gravity?

User Avatar

Asked by Wiki User

Some disadvantages of gravity include the strain it puts on our bodies over time, leading to issues like joint pain and muscle fatigue. Additionally, gravity can make certain physical activities more challenging and can limit our mobility in certain environments. Lastly, gravity can also have negative impacts on objects and structures over time, causing them to wear down and deteriorate.

Isaac Newton is the scientist associated with the theory of gravity. He formulated the law of universal gravitation in the late 17th century, explaining the force that attracts objects towards each other.

Dipper Pines finds the first book in Gravity Falls. The book is discovered in the forest and becomes a central part of the series, containing mysterious secrets and information about the supernatural occurrences in the town.

Why must the intersection of the 3 lines be the center of GRAVITY of the irregularly shaped lamina?

User Avatar

Asked by Wiki User

Friend Hilmar Zonneveld is perfectly and absolutely right. Weight, being a vector, of an object will always act through the center of gravity. Also definition of centre of gravity confirms that whatever be the position the weight would always act through a point known to be center of gravity

What is the speed of gravity on earth?

User Avatar

Asked by Wiki User

The speed of gravity can not be measured because it does not move instead it is a field denting space and time

Gravity does not have a speed but at the Earth's surface it produces an acceleration of 9.08 metres per second per second on a falling object. In other words an object that is dropped will after one second be travelling at 9.08 m/s

Can you turn gravity off?

User Avatar

Asked by Wiki User

NO!!!

However, if you can have an acceleration greater than 10 m/s^2, then you can overcome gravity - hence rockets into space.

Did Sir Isaac Newton discover gravity by watching an apple fall?

Asked by Wiki User

Isaac Newton was observing an Apple Tree when an Apple fell from the tree near someone. So then he got the idea about Gravitational Force. :-)

Is gravity used in space travel?

User Avatar

Asked by Wiki User

If you mean do any manned spacecraft use artificial gravity, the answer is, not so far. But, in the future, large spacecraft may create artificial gravity by rotating them.

To conserve fuel, the gravity of the moon/planets is used to pull spacecraft toward them. And of course the gravity of earth is used to hold/pull on spacecraft so they orbit (circle) around it instead of flying off into space.

Where in the universe is gravity the highest?

User Avatar

Asked by Wiki User

Probably in a 'Black Hole' , because Black Holes draw in everything including light ( electromagnetic waves).

By analogy , one way of thinking of Black Holes is that they are gravitational whirlpools. In flowing water, which may go over a rocky bed, it creates whirlpools, and objects in space may do the same and create Black Holes.

What is gravity speed?

Asked by Wiki User

Gravity doesn't have speed , it has acceleration.

On Earth gravitational acceleration is 9.8 ms^-2.

Often approximated to 10 ms^-2

Does earths gravity affect space?

No. Space is literally nothing. No oxygen, no air, no dust, nothing. objects in space, yes, the earths gravity does affect it. otherwise the moon would just fly away.

How does mass affect acceleration due to gravity?

User Avatar

Asked by Wiki User

According to Newton's law of universal gravitation, the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

However, when considering the acceleration due to gravity on an object near the surface of the Earth, the mass of the object itself does not affect its acceleration. This is known as the equivalence principle, which states that the gravitational mass and inertial mass of an object are equivalent.

In other words, regardless of their mass, all objects near the Earth's surface will experience the same acceleration due to gravity, which is approximately 9.8 m/s². This means that in the absence of other forces, all objects will fall with the same acceleration, regardless of their mass.

When gravity acts on the mas of an object it causes the object to have what?

User Avatar

Asked by Wiki User

An object with mass that is suspended in a gravitational field will have what we call weight. Weight is the term we apply to the force on that object due to gravity.
