If two objects on the same planet are dropped from the same place at the same time

and there is no air resistance, they fall with the same acceleration, and they hit the

ground at the same time with the same speed. Their size, mass, weight, temperature,

color, political affiliation, race, creed, or sexual orientation make no difference.

What is the largest velocity reached by falling object?

The escape velocity from Earth is 11.2 kilometers/second. This is also the speed that an object would reach if it fell onto Earth's surface from far, far away ("infinity" is often used, to simplify calculations) - without air resistance, and without interference by other objects that might also attract it.The escape velocity from Earth is 11.2 kilometers/second.

Will objects fall at the same speed if there is no air?

It is rather subtle. In general yes, if there is no air resistance (or any comparable force) all objects will fall down at the same speed. However this is only strictly true if the masses of the objects are small compared to that of the Earth. This is because we generally attach our coordinate system to the Earth, so if the Earth moves upwards we do not measure it, instead appearing to us as if the object fell down quicker. This is just a consequence of a badly chosen reference frame of course. As an example one would not expect a tea cup to fall down at the same speed as the Moon, because the Moon would actually also pull the Earth towards it. Again if we would properly attach our coordinate system to some place that will remain at rest all objects fall with the same speed.


If you fell in space where would you land?

If you fell in space, you would continue to float or drift in the direction you were originally moving due to the lack of gravity to pull you down towards a specific surface. In the absence of any gravitational pull from nearby objects like planets or stars, you would continue to move in a constant direction.


If both an elephant and a mouse fell down from the 10th level at the same time which one of them would reach the ground 1st?

Both the elephant and the mouse would hit the ground at the same time. In a vacuum or free fall scenario, objects of different masses fall at the same rate due to gravity (ignoring air resistance). This principle was famously demonstrated by Galileo in the 16th century.


When a body of mass 10 kg and 100 kg fall from a height of 100 m which will reach first?

It depends on their relative air resistance. If air resistance were not a factor, the objects would actaully all fall at the same rate. Astronauts confirmed this during a lunar landing by dropping a hammer and a feather. Since the moon lacks an atmosphere, which ordinarily greatly reduces the rate at which a feather will fall, the hammer and the feather fell at the same rate. No matter how massive an object, if wind resistance is not factored in, all objects fall at the same rate on the earth's surface. Higher-mass objects will have more momentum because of their mass (and thus do more damage if they hit something), but have the same 9.8 meters/second2 acceleration on the surface of Earth due to gravity.
