If you drop an object from the sky at what speed does it reach the earth?

When you drop an object it accelerates. The faster it goes the more the air resistance to its motion; this increases proportionally to the square of the speed. Eventually the air resistance becomes as much as the weight of the object. At this point the object stops accelerating. It has reached its terminal velocity. So, if you drop an object from a great height, it will hit the ground at its terminal velocity. What that is depends on the size, shape and mass of the object. For a human being terminal velocity is around 120 mph - almost always lethal. If you drop a mouse from a third floor window the mouse will usually just walk away. Drop a spider from the top of the Empire State Building and the spider will hardly notice the landing.

Why does the pressure drop as you travel upward from earth's surface?
Air pressure is caused by the weight of the atmosphere above an object. When one goes higher, there is less air above and so the pressure drops.
What type of mirror is formed when a mercury drop falls on the earth?
convex!
Why is the water in the Earth is not falling down in the outer space is it because of the shape of the Earth?
Water on Earth is subject to the pull of gravity. Water in the form of clouds is in such tiny drop-lets, that it's suspended until something makes the drop-lets join together, making them heavy enough to be pulled back to Earth.
Where is the temperature on earth?
Antarctica (South pole) where temperatures can drop to -120° or less.
What causes an object to fall to the earth?
Because there is a gravitational force of attraction between every two objects that have mass.The force is proportional to the product of the two masses, and inversely proportional to the square of their separation.The object you drop is attracted to the earth, to the sun, to the moon, to your car, to your dog,and to every planet and star.Since the earth is the largest and closest mass, the attractive force toward the earth is the greatest,and that's therefore the direction in which the object moves.
How does a drop reach the earth?
Gravitational attraction
If you drop an object why does it fall to the ground?
This is explained by Newton's Law of Universal Gravitation. All mass attracts all other mass. The object you drop is attracted by the planet Earth. That's why it falls.
Where on earth can a hammer and feather drop at the same speed?
Inside a safe dropped from a plane.If there were a very good vacuum to drop them in, it would be close. The air resistance of a feather limits its falling velocity more than the resistance on the hammer. When the drag caused by friction equals the weight of the object, it cannot continue to accelerate and falls at a speed called its terminal velocity.
What is the fastest free falling object known to man-is it a rain drop which is liquid or a solid object like a bb?
Everything falls at the same speed so there is no free falling object If everything falls at the same speed then everything is a free falling object... Air resistance or deflection controls the falling speed of any object, this crucial stipulation determines falling speed. I leanred this in flight school.. please someone intelligent communicate with me?
Do all objects not aided by the air fall to the ground at the same speed?
Yes all objects fall at the same speed but there are objects that are aided by the air that don't fall to the ground at the same speed. For example, a feather and a brick. A feather is a object that is aided by air. A brick is a object that wind cannot blow away. If I drop both of them down with the same time down a 100 feet building, then definitely the brick will totally reach the ground first ............ well and it will get crushed into pieces while the feather might be blown away into a different place and reach the ground last.:) :):):):):):):):):)
When you drop a small object is the mass and veloctiy low or high?
Galileo was the first to discover that, when released at the same time, objects with different weights will reach the ground at the same time. This is true because the Earth's gravitation pull is constant. Generally speaking, the velocity of an object will initially be low (zero) and will, given time and distance, increase to reach its terminal velocity. Mass, on the other hand, will remain constant.
Can't drop anything without gravity?
Due to the lack of gravity in outer space, an object and the astronauts in a spaceship, will float. Back on Earth, gravity causes an object to drop to the ground, and keeps our feet firmly on the ground.
Why does the rate of drop change in parachutes?
Parachutes increase the wind resistance experienced by a falling object, thereby slowing the speed of decent.
What happens when a falling object stops?
It suddenly stops and hits wherever it's landing. ---------------------------------------------- When a falling object stops accelerating then the body would continue moving with the speed attained. This speed is known as terminal speed. This is what happens when a rain drop falls from a large height through the atomosphere.
How do you find the velocity of a falling object?
If an object is in free fall, its speed grows at the rate of 9.8 m/s every second.To find its speed at the end of some period of time, multiplyspeed = (number of seconds after the drop) times (9.8 meters per second2)Since the object is falling, the speed is in the downward direction. Knowing boththe speed and the direction tells you the velocity.
What causes speed drop in motor?
1) If current, at 'on load' condition, reach or cross its rated value, then the speed of the motor will be decreased. 2) If there is any voltage droop occurs in the incoming supply then the speed of the motor will be decreased.
How could you determine if it will take the same time for the lighter and heavier object to reach the ground when dropped at the same height in the same time?
drop a heavy object and a light object from the same height at the same time. time it with a stopwatch, or just watch them.
