Freely Falling Objects and Acceleration Due to Gravity

Check us out at http://www.tutorvista.com//videos
A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name. It is known as the acceleration of gravity - the acceleration for any object moving under the sole influence of gravity. A matter of fact, this quantity known as the acceleration of gravity is such an important quantity that physicists have a special symbol to denote it - the symbol g. The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s. There are slight variations in this numerical value (to the second decimal place) which are dependent primarily upon on altitude. We will occasionally use the approximated value of 10 m/s/s in The Physics Classroom Tutorial in order to reduce the complexity of the many mathematical tasks which we will perform with this number. By so doing, we will be able to better focus on the conceptual nature of physics without too much of a sacrifice in numerical accuracy

Thank you :D

Very Good.

this helps! thanks

@kandibee air resistance affects more on greater surface..., if both have same(or almost the same) surface, they will reach at the same time... ;)

@norlandanielbustillo wow what was the reason for that then?

My physics teacher (10 grade) showed us yesterday an ¨experiment¨ of free fall in which he threw a key and a piece of paper at the same time and height and obviously the key reached the ground faster... we all thought that it was because of weight, but then he made the paper into a ball and tried again and both reached at the same time.... AMAZING!
