The speed of a falling object keeps changing as it falls.
If an object falls 250 feet to the ground and there is no air, then it takes about
4 seconds to fall, and it hits the ground at about 86.5 miles per hour (127 fps).
If the object falls through air, then the speed it picks up depends on its weight
and shape ... a sailplane falls slower through air than a rock does, but take away
the air, and a rock and a feather fall together.
Ignoring air resistance ... Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight makes no difference.
If you can ignore the effects of air resistance, then . . .The speed of a falling object isS = s0 + G TS = speed at any time after it's droppeds0 =initial speed you gave it when you dropped it; if you just openedyour hand and let it roll out, then s0 is zero.G =acceleration of gravity; On Earth: 9.8 meters (32.2 feet) per second2T =length of time it has been falling.That's the speed of the falling object, also the magnitude of its velocity.The direction of velocity is on a line toward the center of the Earth, typicallyreferred to in most places as "down".
The acceleration due to gravity on Earth is approximately 9.81 meters per second squared. This means that for every second an object is in free fall near the surface of the Earth, its speed increases by 9.81 meters per second.
No, distance does not affect the speed of a falling object. In a vacuum, all objects fall at the same rate regardless of their distance from the ground, known as the gravitational acceleration of 9.8 m/s^2.
There is no definite speed for free falling. If an object is released somewhere above the earth, the speed is changing every single moment. It is never the same speed it was before at any time; only until an object releases terminal velocity where it is moving at a constant speed. This is different for every object. The acceleration due to the gravity of the earth is 32 feet/second^2. This means that for every second that passes, an object is moving 32 feet/second faster than it was the second before.

On Earth, but without any air. . . 334 feet.
There is no definite speed for free falling. If an object is released somewhere above the earth, the speed is changing every single moment. It is never the same speed it was before at any time; only until an object releases terminal velocity where it is moving at a constant speed. This is different for every object. The acceleration due to the gravity of the earth is 32 feet/second^2. This means that for every second that passes, an object is moving 32 feet/second faster than it was the second before.
The speed of an object falling freely without air resistance from a height of 16 feet can be calculated using the equation V = √(2gh), where V is the final velocity, g is the acceleration due to gravity (32 ft/s^2), and h is the height. Plugging in the values, the speed of the object at impact would be approximately 28 feet per second.
Acceleration of gravity near the surface of the earth is 9.8 meters (32.2 feet) per second2. Downward velocity after 2 seconds = 19.2 meters (64.4 feet) per second.
The speed of an object falling increases by 9.81 m/s every second due to gravity near Earth's surface. This rate of acceleration remains constant until other forces, like air resistance, come into play and may impact the rate of change in speed.
When an object is dropped near the Earth's surface, and it experiences no air resistance, then its speed after 3 seconds is 29.4 meters (96.5 feet) per second, and its velocity is directed toward the Earth's center of mass, nominally the Earth's geometric center, colloquially referred to in the bourgoise vernacular as "down".
Neglecting the effect of air resistance, the speed of any falling object ... including ice cubes ... is always 32.2 feet per second greater than it was one second earlier.
