If one angle is 80 degree and otjer angles are in ratio on 3 : 7
Answer:
Well, we've all heard of Galileo Gallelays famous expirement that showed that gravity effects all objects equally, regardless of their weight.
What we can't forget to take into account is that the objects he dropped of the tower had very similar, if not identical surface areas. This means that they had the same aerodynamic properties and the same amounts of drag.
If we performed the drop in question on Earth, the ball would hit the ground first as the paper slowly drifts to the ground. This is such because the paper has a much larger surface area and more drag. The force of gravity is the same on both objects, as they are dropped from the same height. Since drag is in essence just friction caused by air, it takes more energy to bring the paper down to the Earth comapared to the ball and so the ball has more energy being used/applied so it falls faster and in less time.
The only way the two would reach the bottom of the drop at the same time is in a place with no drag…space. Space is a vacuum so there is no air to cause any kind of drag. In this scenario…both objects hit the ground at the same time since gravity effects them equally and there is no drag to take into account. This was shown on one of the Apollo moon missions when an astronaut dropped a sheet of foil and a hammer and, as previously stated, they hit the ground at the same time.
