How fast is terminal velocity for a penny if it is in a vacuum?

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.

Terminal velocity is achieved when an object?
is falling as fast as air resistance will allow it to.
How fast do objects fall through air?
An object's top speed is called Terminal Velocity.The terminal velocity of an object can be calculated via a formula. See the related links.
What is terminal velocity and how to control it and why it occurs?
Terminal velocity is when air resistance balances out with gravity. For humans it's usually around 2000 ft of falling, gravity accelerates the person towards the ground at about 9.8m/s, as said person speeds up, air resistance increases and it becomes harder to accelerate. Terminal velocity is the point at which one may no longer accelerate. To control it: more air resistance = slower descent (terminal velocity comes sooner and is not as fast (i.e.parachutes), less air resistance = faster descent, it may take longer to reach terminal velocity as it is a much higher speed.
What is the terminal velocity of gravity?
gravity is a force that defines terminal velocity, along with friction and others..objects can only fall so fast due to friction..on earth gravity pulls at 9.8m/s2 while at the event horizon of a black hole gravity pulls faster then the speed of light, which is why light cannot escape it
What is refractive index?
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium.A simple, mathematical description of refractive index is as follows:n = velocity of light in a vacuum / velocity of light in mediumHence, the refractive index of water is 1.33, meaning that light travels 1.33 times as fast in a vacuum as it does in water.
What veritables determine how fast an object will be moving when it reaches terminal velocity?
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
How does an object achieve terminal velocity?
99% of the object cause terminal velocity is determined from an object when it is going as fast as it will go
The greatest velocity a falling object reaches?
The greatest velocity that a falling object can achieve is termed, terminal velocity. The equation for terminal velocity is equal to the square root of (2mg / (air density * projected area * drag coefficient))
Terminal velocity is achieved when an object?
is falling as fast as air resistance will allow it to.
If you throw a tennis ball of the Empire State Building how fast will it go?
It will go as fast as it's terminal velocity
How fast can a man fall to earth from airplane?
The fastest rate a human can fall is called terminal velocity. Terminal velocity is when the gravity force upon an object is equal to that of the wind resistance. The normal terminal velocity of a human is around 125 miles per hour.
How fast do rubber balls go if they fall off a tower?
It depends on the height of the tower and the terminal velocity of the specific rubber ball. Many objects with a specific gravity near 1 have a terminal velocity of about 120 miles per hour.

How fast does a person fall out of an air plain?
About 55 meters per second is "terminal velocity". http://hypertextbook.com/facts/JianHuang.shtml
What animals are carried by a tornado mile unharmed?
Possibly insects. Their small size means they have a low terminal velocity, so they will not be moving very fast when they fall out.
