## amishra 3 years ago What is terminal velocity? Is it in the presence or absence of air resistance? Examples please! Why does a piece of falling paper reach its terminal velocity in a much shorter time than a falling book?

because of air resistance

2. fall2012

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling...

When you drop a piece of paper and a book, gravitational force causes them to accelerate, however, due to the light nature of the paper, air resistance acts on it and as such causes it to decelerate while the book is able to use it weight to over the air resistance...

Oh! I got it! Thank you~!!!! :D

So basically, terminal velocity is a state of constant velocity, when a free falling object reaches a maximum velocity which is nulled by air resistance. Am I right?

7. fall2012

well not precisely air resistance, if the object is in water, then the resistance will be from water. The literal definition: is the constant speed a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration

Oh, I got it now. Thank you so much!

aiit! Smile today!
