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.

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?

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?

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.

Is there gravity on the stars?

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?

User Avatar

Asked by Wiki User

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.

Does mass and weight change with location because the force of gravity changes?

User Avatar

Asked by Wiki User

Mass does not change!!! Whatever the force of gravity, the object contains the same amount of matter.

However, weight does change because the gravitational acceleration changes.

Can a body rotate under the action of gravity with respect to its weight?

Asked by Wiki User

no a body can,t be rotate about its centre of gravity

What effect does zero gravity have on a spine?

User Avatar

Asked by Wiki User

In zero gravity, the lack of gravitational force causes the spine to decompress and elongate. This can lead to increased height and temporary relief from spinal compression. However, prolonged exposure to zero gravity can weaken the spine and lead to muscle atrophy and loss of bone density, which can have negative long-term effects on spinal health.

Is it true that Winds cannot blow against the force of gravity?

User Avatar

Asked by Wiki User

No, it is not true. Winds can blow against the force of gravity. Wind is the movement of air, and it can be influenced by various factors such as atmospheric pressure gradients and temperature differences, rather than solely being driven by gravity.

What comes from the mass of the world our mass and the force of gravity?

User Avatar

Asked by Wiki User

The force of gravity is what keeps us grounded on Earth and is determined by the mass of the world (Earth) and our own mass. The interaction between these masses results in the force that pulls us towards the Earth's center.

Why did the byzntine military grow weaker?

User Avatar

Asked by Wiki User

There were several factors that contributed to the decline of the Byzantine military. These included constant wars and conflicts that drained resources, frequent changes in leadership and political instability, the rise of powerful enemies such as the Seljuks and Ottomans, and a decline in the quality of the military education and training system. Additionally, the reliance on foreign mercenaries weakened the effectiveness and cohesion of the Byzantine army.

How does gravity vary and why?

User Avatar

Asked by Wiki User

Gravity varies depending on the mass of an object and the distance between objects. According to Newton's law of universal gravitation, the force of gravity decreases as the distance between objects increases. Additionally, the greater the mass of an object, the stronger its gravitational pull. This variation in gravity is why objects on Earth feel a stronger gravitational pull compared to objects in space.

Center of gravity of a flat plate?

User Avatar

Asked by Wiki User

C.G of a regular shaped plates of uniform thickness will be at its centre. But if it is irregular, it can be inside or outside the lamina as well.

please give more details of shape and if it is solid and has uniform plane etc.
