The traditional acceleration due to gravity (9.8
meters per second per second) is assuming a vacuum. However, for short
falls, it works out well.
For longer falls, the force of gravity is eventually equaled by the force of
air resistance. At this time the speed remains constant. As you are likely
aware, in order to have a change in velocity, an unbalanced force is
required.
The "terminal velocity" is determined by the shape of the object. Sky
divers can speed up and slow down by changing the shape they present to the
relative wind (the air going by them). Ultimately, they open their
parachute and greatly increase the for of the air resistance... (luckily!)
slowing them down considerably.

An object with a mass of 8 kg is dropped and takes 2 s to hit the ground. Then another object with a mass of 16 kg is dropped from the same point. How long does it take to hit the ground?
2s
How long in seconds would it take for an object to fall 120 meters?
depends on weight of object and wind strength.normally heavy objects will drop down faster than lighter objects.
How long does it it take an object of 4 kg to hit the ground considering another object with a mass of 2 kg took 3 seconds to hit the ground?
Assuming they were in a vacuum, if both objects were dropped from th esame height, then both take the same length of time to reach the ground. All masses fall with the same acceleration, reach the same speed in the same period of time, and hit the ground at the same time. Otherwise and if there is an atmosphere or if they are dropped from different heights, you have not presented information; shape and size are the most important factors.
How long would it take for an object dropped from 54.6 meters to hit the ground?
D = 1/2 g T2T = sqrt(2D/g) = sqrt( 109.2 / 9.8 ) = 3.335 seconds(rounded)
How long does it take an object with a velocity of 2.5 meters a second up to fall 15m?
15 m divided by 2.5 m s-1 is 6 s.
How long will it take an object dropped from a window to fall a distance of 78.4 meters?
4 Seconds
Does an object dropped from twice as high take twice the time to fall?
No, an object dropped from twice the height will not take twice the time to fall. This is because the time it takes for an object to fall depends on the initial velocity and acceleration due to gravity, not just the height from which it is dropped.

How long will it take an object to fall 60000 feet?
It would take approximately 50 seconds for an object to fall 60,000 feet in a vacuum without air resistance. However, in reality, factors like air resistance would affect the actual time it takes for the object to fall.
How long would it take to fall if you dropped all the water in the world on top of new york city but funneled it so it could only fall in that one spot?
Five minutes
How long will it take object to hit the ground falling 500 ft?
It will take approximately 7.1 seconds for an object to fall 500 feet assuming free fall in a vacuum. This time can vary slightly depending on air resistance and other factors.
How long will it take an object dropped off the Leaning Tower of Pisa to reach the ground?
It depends plus, you can't go to the top of the leaning tower of Pisa.
How long in seconds would it take for an object to fall 120 meters?
depends on weight of object and wind strength.normally heavy objects will drop down faster than lighter objects.
How long does it take for felt to fall?
It depends from how high and the weight of it but the acceleration will be 9.8m/s2 if gravity is the only force acting upon the object.
How does gravity make things fall?
The weight of the object causes gravity to take the object falling
How long will it take an object dropped from a height of 500 feet to hit the ground?
Assuming the object is dropped from rest and neglecting air resistance, it would take approximately 7.0 seconds for the object to hit the ground from a height of 500 feet. This is based on the formula t = sqrt(2h/g), where t is the time, h is the height, and g is the acceleration due to gravity (approximately 32.2 ft/s^2).
How long does it take an object to fall 176.4 meters in a vacuum?
The time it takes for an object to fall a certain distance in a vacuum can be calculated using the equation for free fall: time = sqrt(2 * distance / gravity). Plugging in the values, it would take approximately 4.74 seconds for an object to fall 176.4 meters in a vacuum since there is no air resistance.
