The weight of a Nickel is 5 grams or 0.005 KG
For example
If a Nickel is dropped from a height of 1 metre (NEAR EARTH SURFACE GRAVITY)
the velocity just before impact is 4.427188724235731 metres per second
if the mass of the object is 0.005 Kg
then the kinetic energy of the object just before impact is 0.049 J
This is obviously directly proportional to the air flow and this example assumes that air friction is negligible.

while we are here lets calculate the impact force of the falling object..
now where's my beer.
the change in kinetic energy of the nickel is equal to the net work chivied on the object
therefore
the average impact force X distance traveled equals the change in kinetic energy
therefore the distance traveled is 0.02 metres
but this is obviously directly proportional to the density of the surface that it falls into, for this example i have used sand.

How do you find the kinetic energy of a falling nickel?
1) measure its mass and velocity. 2) Measure where its falling from. (the kinetic energy will equal the potential energy up to the instant the nickel stops).
What is energy from potenttial energy kinetic energy would be what?
A falling rock. In the air it has potential energy, as it falls it gets kinetic energy.
How does hydropower transformed?
The potential energy of the falling down water transfers to kinetic energy. The kinetic energy turns turbines that are connected to electric generators where the kinetic energy transfers into electric energy.
Why the kinetic energy is zero for object falling towards Earth from space?
It isn't. Kinetic energy is 1/2 x mass x speed squared, so if an object has mass, and it moves, it follows that it has kinetic energy.
How does velocity have an effect on kinetic energy?
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.

What accounts for the aircraft carrier having a greater kinetic energy than the falling nickel?
The aircraft carrier has a greater kinetic energy because it is so much more massive. Kinetic energy = (1/2)mv2, where m is mass and v is velocity.
What kind of energy do falling boulders have?
Kinetic energy.
What happens the the kinetic energy of a falling object?
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
Is a falling ball potential or kinetic energy?
it is kinetic because it involves releasing the energy.
What form of energy is a falling rock?
That is a trick question, but I believe it is kinetic energy.
A boulder falling through the air has what type of energy?
a boulder falling through the air still has some potential energy, but some of its potential energy has changed to kinetic energy...so it has both potential and kinetic!
What is energy possessed by moving or falling bodies?
kinetic energy
A falling rock has kinetic energy?
True.
What is energy from potenttial energy kinetic energy would be what?
A falling rock. In the air it has potential energy, as it falls it gets kinetic energy.
What is the energy in an object about to fall?
the energy in an object about to fall is potential energy then kinetic energy because when the object is not falling, it has potential energy but when it's actually falling, it has kinetic energy.
Is a falling rock a kinetic reaction?
There is no such thing as a kinetic reaction. Any moving body has kinetic energy. When a rock falls, its gravitational potential energy is transformed to kinetic energy.
