It depends if it is affected by air resistance or not. If not then all objects close to the surface of the Earth have an acceleration of 9.81ms^-2 in free fall. If it is affected by air resistance you need all sorts of more information to answer that question, like the drag coefficient of the air.
you have to say JESUES MAN
In order to come up with an answer, we have to impose a couple of rules: 1). we're trying this on the earth 2). we're ignoring the effects of air 3). it's not moving at the beginning of the 5 seconds ... that's when you drop it from your hand Then the rock falls 400 ft in five seconds. What's really interesting is that it doesn't matter how much it weighs. ALL rocks fall the same distance in 5 seconds.
On earth it is responsible for air pressure. There are about 15 pounds of air above every square inch of the earth's surface. Or in other words, the volume of a column of air on Earth about a hundred miles high and a square inch in area weighs 15 pounds.
Any object near the surface of the earth, falling without air resistance and under the influence of only gravity, falls 789 feet. (rounded) Its weight makes no difference.
The Earth doesn't lose air, even for a few seconds.
The temperature of the air falls at night because the earth loses heat by
It loses air, generally going flat.
the earth will die out
Weather is a mix of things that happen from day to day in the air around Earth.
What will happen is that the air population will be more of a threat too planet earth. Because when people die they MIGHT leave the factories on an the air population. And the earth will die because of air population.
we all would die
It loses moisture if cooled below its dew point. It becomes more dense, and that causes it to move toward areas where the air is less dense.
If Earth's gravitational field were to collapse for a few seconds, objects and structures would experience weightlessness and potentially float away. This could disrupt ecosystems, cause widespread damage, and lead to injuries or fatalities as things become temporarily untethered. On the positive side, some may find the experience of weightlessness exhilarating for a brief moment.
The most likely factor that would cause a communications satellite orbiting Earth to return to Earth from its orbit would be atmospheric drag. As the satellite moves through the Earth's atmosphere, it experiences friction with air molecules which can slow it down and cause its orbit to decay, eventually leading to re-entry into Earth's atmosphere.
the engine will start up and run for a few seconds then quit
no air and no oxygen
