If the object that falls is sufficiently dense and streamlined, so that the effects
of air resistance can be neglected, then you can estimate the height from which
it fell like this:
-- Time the fall, from the instant the object is released until the instant it hits the ground.
-- The distance it fell is [ 16.1 T2 ] feet, or [ 4.9 T2 ] meters.
The height of a tall building can easily be measured by using a barometer.
There are two convenient methods.
1). Drop the barometer from the roof of the building. Time its fall, from the
instant the barometer is released until the instant it hits the ground. The
height of the building roof is [ 16.1 T2 ] feet, or [ 4.9 T2 ] meters.
2). Tie the barometer to the end of a long tape-measure or rope. With the
barometer as a weight to resist the inaccuracy that would be introduced by
the wind, slowly pay out the tape or the rope from the edge of the building's
roof, until the barometer just touches the ground. At that point, either read
the height directly from the tape, or mark the rope where it touches the roof,
and measure the length of rope between the barometer and the mark later.
The formula to determine the velocity of an object in free fall is v = gt, where v is the final velocity, g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth), and t is the time the object has been in free fall.
The formula for calculating the height of an object in free fall based on its velocity is h v2 / 2g, where h is the height, v is the velocity, and g is the acceleration due to gravity.
The formula to determine the velocity of an object in free fall is given by v = gt, where v is the final velocity, g is the acceleration due to gravity (usually taken as 9.81 m/s^2), and t is the time the object has been falling.
The object is said to be in free fall.
An example of free fall is when an object is falling under the sole influence of gravity, without any other forces acting on it. For instance, dropping a ball from a height and watching it fall straight downwards with no air resistance would be considered free fall.

Because they undergo an acceleration. Free fall velocity is the function of a square.

The object is said to be in free fall.
An object is in free fall when only gravity and air resistance (drag) are acting on it. In space, free fall excludes drag.
An example of free fall is when an object is falling under the sole influence of gravity, without any other forces acting on it. For instance, dropping a ball from a height and watching it fall straight downwards with no air resistance would be considered free fall.
In free fall, the object converts its potential energy at height h into kinetic energy as it falls. The conservation of energy principle states that the total energy (sum of potential and kinetic energy) of the object remains constant if we ignore factors like air resistance. Therefore, as the object falls from height h to the ground, its potential energy decreases while its kinetic energy increases, with the total mechanical energy remaining constant throughout the fall.
An object in free fall is one that has only the force of gravity acting upon it.
A falling object.
Free fall is exactly what the name suggest. A free fall is when an object falls downwards with NO OTHER FORCE acting upon it. An example of a free fall would be if you pushed your friend off an airplane. while he is falling he is experiencing no force but gravity (a free fall). Don't worry though, he had a parachute he deployed later on.
The only force that can act on an object in free fall is gravity.
