gravity :D
Gravity pulls objects towards the center of the Earth, so people on the opposite side are also pulled towards the center and stay upright due to the balance of forces acting on their bodies.
Every planetary body (including the Earth) is surrounded by its own gravitational field, which exerts an attractive force on all objects. (http://en.wikipedia.org/wiki/Gravitation). Because of gravity of earth we stay on the earth.
Satellite objects are set at speed and distance that its' orbit around earth equal earth rotation. It's centripetal acceleration must be just balance with gravity of the earth or v2/r=GM/r2.
coz you can
Yes because large asteroids heading for earth are Near Earth Objects and if they were to hit many people can lose their lives.
The Earth does not stay at rest due to the gravitational pull of other objects in the universe, such as the sun and moon. These forces create a dynamic system of interactions that keep the Earth in motion, causing it to orbit the sun and rotate on its axis.
Objects in space, like satellites and astronauts, stay in orbit by moving at a high speed horizontally. This speed creates a balance between the force of gravity pulling them towards Earth and their forward motion, allowing them to continuously fall towards Earth without actually hitting it.
The first people to use body parts to measure objects were the first people on Earth. This was their only way of measuring anything.
If there was no friction on Earth, objects would not be able to stay in place and would slide or float away. People would have difficulty walking or driving as there would be no traction. Machines and mechanisms that rely on friction to operate, such as brakes and gears, would not function properly.
stay away from earth away from people
Earth's gravitational pull. See attached link for more information.
The earth's pull on objects is the force of gravity.
