What's the difference between impact speed and terminal velocity? I'm reading a book that gives a shortcut about how to calculate "The speed at impact in the y-direction when falling from rest" and it gives the eguation vt=9.8t.

Impact Speed: The speed at which a falling object hits the ground

Terminal Velocity: The fastest speed an object can go as its acceleration is slowly decreased over time due to air resistance (air resistance works against gravity; eventually, the force of air resistance = the force of gravity)
