Yes, at the center it becomes zero.
Yes it does.
No, the gravity between Jupiter and its moons acts towards the centre of Jupiter.
Gravity acts in the direction directly towards the centre of the Earth. Drag acts in the direction directly opposite the bird's movement.
The centre of gravity is the point trough which the whole weight of the object seems to act.
i was taught that on the moon, your weight would be 11% of your weight on earth.
N o! the upthrust can not act at a distance because it acts on the centre of gravity of the object submerged in water in the opposite direction of weight.
Because the earth behaves like a magnetic field with the center of the earth pulling everything towards it.... do the math.
Centre of gravity of a body is defined as the fixed point in the body through which the weight of the body would act in whatever position the body is kept. Hence if the CG is at higher point of the body then there will be more chances for falling or toppling. Because earth would always attract the body towards its centre. Hence as CG is at the lowest level as possible then the stability would increase. Hence in case of ships the CG will be maintained to be at most bottom so as to avoid toppling.
An object must have mass for there to be weight. There also must be another mass (such as Earth) that exerts a gravitational pull on the object for there to be weight.
Like any other human being on this earth. Hopefully, that equates to respect and kindness.
to act HOSTILE is to act aggressively or defensively towards other people
1. Weight- caused by gravity pulling it towards the earth. 2. Lift- caused by a difference in pressure between the upper side and the underside of the wing. 3. Drag- caused by friction. 4. Thrust- caused by the engines pushing air in the opposite direction of travel.
