What is the terminal velocity

I grabbed this right from Wikipedia.

The terminal velocity of an object falling towards the earth, in non-vacuum, is the speed at which the gravitational force pulling it downwards is equal and opposite to the atmospheric drag (also called air resistance) pushing it upwards. At this speed, the object ceases to accelerate downwards and falls at constant speed. An object moving downwards at greater than terminal velocity (for example because it previously used power to descend, it fell from a thinner part of the atmosphere or it changed shape) will slow until it reaches terminal velocity.

good answer, but do you know what it is in km/h at sea level?

That would all depend on the mass of the object falling. Here's a link to the Wikipedia page that gives the full explanation, as well as the equation to figure out what the terminal velocity is for the mass you are using. http://en.wikipedia.org/wiki/Terminal_velocity

Here's the math

v_t=√(2mg/(pAC_d ))

m=mass, g= gravity, p= density (air), A= surface area of object, C_d= coefficient of drag v_t = term velocity
