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.
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
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
NO!!!
However, if you can have an acceleration greater than 10 m/s^2, then you can overcome gravity - hence rockets into space.
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.
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.
Gravity doesn't have speed , it has acceleration.
On Earth gravitational acceleration is 9.8 ms^-2.
Often approximated to 10 ms^-2
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.
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.
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.
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.
no a body can,t be rotate about its centre of gravity
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.
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.
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.
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.
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.
