An object falling through the air will have a terminal velocity of approximately 120-140mph. The less "wind resistance" it has the faster it goes. Although the penny has less wind resistance than say, an elephant, it still is not an ideal shape for moving through the air. Being flat, it can flutter, spin, 'float', etc, and that will slow it down.
If the penny is in a vaccum, the penny has no terminal velocity because verminal velocity is when the resistance against the falling penny is equal to the force of gravity. So if it is in a vaccum, it has no forces resisting the fall, and it has no terminal velocity.
The velocity of the penny when it hits the ground can be calculated using the formula: velocity = acceleration due to gravity x time taken to fall. The acceleration due to gravity is roughly 9.81 m/s^2. Therefore, the velocity of the penny when it hits the ground is 44.145 m/s.
The kinetic energy of an object is greatest when its velocity is at its maximum. Kinetic energy is directly proportional to the square of the velocity of the object, so as the velocity increases, the kinetic energy increases exponentially.
The greatest velocity a falling object reaches is called the terminal velocity.For an object falling at the terminal velocity, the weight force of the objectis balanced by the drag force and buoyant force on the object.W + FDRAG + FBUOYANT = FNET = 0.0
I say NO. If you mean it is dropped and falls vertically. Discover Channel's "Myth Busters" tried to determine if a bullet would kill you if it was fired directly vertical and falls on its own. The bullet or penny would fall at terminal velocity which is about 120mph. However, they will tumble which slows them down more. This velocity and their mass is not enough to kill you.

The greatest velocity, achieved when the acceleration due to gravity is balanced by the aerodynamic deceleration, is called the terminal velocity.
The velocity of the penny when it hits the ground can be calculated using the formula: velocity = acceleration due to gravity x time taken to fall. The acceleration due to gravity is roughly 9.81 m/s^2. Therefore, the velocity of the penny when it hits the ground is 44.145 m/s.

The name for it is "terminal velocity". What it is depends on what the object is.
