What direction does gravity act on a plane?
Always toward the center of the Earth.
What is positive Gravity?
gravity is the earths pull on you. it is located in the center of the earth, and that is why we stand on the ground instead of floating upwards. you dont really feel it pulling on you but its there.
In which direction does gravitional force apply?
The concept of direction in relation to gravity is complex. Gravity is a property of matter and can be visulised as a force pulling towards the centre of mass of that matter. Thus YOU as a body of matter have a mass and a gravitational force of your own. However, on the Earth, your mass is much smaller than Earth's so you feel Earth's gravity pulling you towards its centre. On the Moon you woud feel yourself being pulled towards the centre of mass of the Moon. Thus as you can see what happens applies depends on where you are - but - it is always towards the centre of mass.
Why do you have to use force to lift objects?
Because there is a force of gravity constantly pulling it towards the center of earth. When you exert enough force to over come the gravity acting on an object it is lifted
Is there a force that cancels out gravity?
The fact that we stand on the surface of the Earth - rather than falling right through to the center of the Earth - indicates that there is. The two forces - the Earth's surface pushing us upward, and Earth's gravity pulling us downward - cancel in this case. In the above, the forces cancel out -- we are pulled down, but the floor pushes up at the same force (different direction. But is there a force that cancels out gravity? The best I can think of is an Earth above and an Earth below, so that the two opposite directed forces cancel out. Although in orbiting, the centrifugal force cancels (equal and opposite) of gravity.
In which direction does gravity pull the moon?
The Earth's gravity pulls the Moon towards it and its center.
In which direction does gravity pull you?
Gravity acts as though you were being pulled to the center (of the earth, in my case).
What direction does gravity act on a plane?
Always toward the center of the Earth.
Where is the direction of acceleration due to gravity?
It's toward the center of the Earth. We call that direction "down".
What is the reaction force if Sun's gravity pulling on Earth is the action force?
Earth's gravity pulling on the Sun.
In what direction do the gravitational forces act?
Gravity is essentially the attraction of masses between each other. So gravity between the earth and moon, for instance, points in both directions between those two objects. The earth's gravity is pulling the moon and the moon's gravity is pulling the earth.
What is positive Gravity?
gravity is the earths pull on you. it is located in the center of the earth, and that is why we stand on the ground instead of floating upwards. you dont really feel it pulling on you but its there.
Why is acceleration due to gravity zero at the centre of the Earth?
Acceleration due to the earth's gravity is zero at the center of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. Simplistically, acceleration due to gravity decreases as distance from the center decreases. At the center the distance is zero, hence gravity is zero.
Why does gravity keep us down on the ground and not up in the clouds?
It is pulling us toward the center of the earth. We are lucky we live on Earth and no some planet with a weak gravity where we can fly in the clouds.
In the earth where the gravity of the earth becomes zero?
In a perfectly-shaped sphere, with a smooth surface, and composed of exactly the same substance with the same density throughout it, the force of gravity is zero at the exact center of the sphere. That does NOT mean that 'gravity becomes zero' at the center. It means that at the center, for every speck of mass pulling on you in any direction with any force, there's another speck of mass pulling you in exactly the opposite direction with exactly the same amount of force, so the whole thing adds up to zero. In the real Earth, we can't tell exactly where that point is, because the Earth is not a perfect sphere shape, It doesn't have a smooth surface, and we don't know every last little detail about the distribution of mass inside it.
What is the pulling force that the planet earth has?
gravity? :)
Which direction is gravity pointing?
The forces due to gravity act along the line between the centers of two masses. That means that the Earth is attracted toward your center of mass, and you are attracted toward the center of the Earth, both with equal force. We typically refer to that direction as "down".
