Law of gravity

Law of gravity
The prestigious Italian researcher, Galileo had demonstrated by dropping a few rocks from the inclining tower of Pisa that regardless of the distinction in weight, every one of the stones achieved the earth in the meantime. Be that as it may, you don't trust it, isn't that right?

On the off chance that you don't have confidence in the conclusions inferred by Galileo, let it be so. Be that as it may, you can yourself direct some such examinations. What's more, for this, you require not climb a tower. 


You can watch everything without anyone else by doing a basic analysis at your home itself whether the objects of various weights dropped from a similar tallness achieve the ground in the meantime or not. To do this examination, you will require a long wooden board—a meter long will do—and few coins of various weights. There's nothing more to it. Presently make a column of coins along the length of the board and hold the board on a level plane with both your hands, over your head. Tc increment the separation between the board and the ground, you can remain on a stool or table. Presently tilt the board towards the ground so that every one of the coins slide down at the same time. Before doing as such, ask your companion well ahead of time to observe painstakingly whether every one of the coins touch the ground in the meantime or not.


In the event that you have tilted the board in a manner that every one of the coins slide down in the meantime, then they will fall on the ground at the same time attributable to the impact of the gravitational draw of the earth which pulls in everything towards it with a similar speed. In the event that a similar trial is led with a coin and a plume, the outcome won't fit in with this standard. The coin will achieve the ground sooner than the quill. Why? The explanation for it is the resistance made by the air in the method for the quill. Be that as it may, if the coin is put on the plume, both will achieve the ground in the meantime, as for this situation, the air does not. Straightforwardly deter the smooth fall of the plume.
