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.

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.

Forces might be described as contact and non-contact forces.

Contact forces would include friction, pressure, etc.

Non-contact forces are more basic and include gravitational force, electromagnetic force, electro-weak force, and others.

ag = GM/d2.

ag is the gravitational acceleration; G is the gravitational constant; M is the mass of the primary body (e.g. planet); d is the distance between the centres of mass of the primary and secondary bodies.

Specific gravity is the ratio of the density of a substance to the density of a reference substance, typically water for liquids and solids, and air for gases. Specific gravity can be measured using a hydrometer, which is a device that consists of a weighted glass or plastic tube that floats in the liquid. The hydrometer has a graduated scale that is used to read the specific gravity of the liquid. Another method is to use a digital density meter, which uses electronic sensors to measure the density of the substance. In this method, the substance is placed in a container and the electronic sensors measure the weight and volume of the substance to calculate its density and specific gravity.

Humans grow too, yet we are pulled down.

Plants, like most living organisms, grow by cellular reproduction. This replicates cells, making a plant larger.

A hormone called auxin stimulates cell growth. The hormone is gravotropic, which means in plant shoots, it stimulates cell growth upwards, the opposite way in which gravity is forcing the plant.

Birds is use they wing to keep them up. They flap and up in air.

By moving their wings in a flapping motion, along with angling their bodies and internally measuring their speed, they are able to maintain a constant elevation. Some birds travel in V forms to ease the burden on the bird behind them, constantly swapping positions to keep any one bird from having a harder time than another.

NO!!! Gravitational acceleration on Earth is approximately 9.8 ms^-2 . It applies to ALL objects.

Force of Gravity ???? Force = mass x acceleration.

So the Force is subject to the mass of a given body. This is a mathemticl expression of Newton';s Second Law of Universal Dynamics.

Gravity is used because if the rollercoaster is too high you could get a nose bleed or even die. So a lot of science is put into a rollercoaster to check the height and stuff. You will probabaly learn this in like the 5th or 6th grade. It has to do with velocity ,gravity,air pressure and stuff of that sort.

A ball is thrown up at 12m/s. Assume no air resistance and you have to assume that the gravitational field is constant at 9.8ms^-2 then

(for this x will represent the number of seconds since the object was first at a height of 0m)

to work out the speed at each point in time we use the equation 12-9.8x

the 12 is the original speed and the -9.8 is the acceloration towards the earth and the x is the seconds if we calculate the units

12m/s+(-9.8m/s/s*xs) = 12m/s + (-9.8x)m/s this means that the end units are m/s which is speed.

to work out the position we have to times by time again to get m

so the (position at time x) = 12x+(-9.8)*(x^2)

then to find the highest point use the formula x=-b/2a which in this case as we are using the quadratic -9.8x^2+12x+0

-b = -12

2a = -19.6

-12/19.6 = about 0.61 seconds (this is at what time it reaches its highest point) as we have x we can work out the height which is

-9.8(0.61)^2 +12(0.61)+0 = 3.67m

so in answer to the question proposed as an answer for the original question the object would reach 3.67 meters

I think you need to try and clear up what you actually want as an answer for the original question before you can get a proper answer to it.

In all the bars Ive shot at here on Oklahoma,neither is required unless specially requested by opponent and both parties agree to that before the break.

Europa's Gravity is 1.314 m/s2 or (0.134 of earths gravity)

9.8 m/s2

----------------------

Yes this is the average value of acceleration due to gravity near by the surface of the earth. As we go higher and higher level this g value decreases and becomes almost negligible. Same way as we go deeper and deeper the g value decreases and at the centre of the earth its value becomes zero.
