Hello Pal❤❤
here's ua answer :
Galileo proved with his experiments that when objects are dropped simultaneously, they will reach the ground at the same time regardless of their masses and air resistance. In another set of experiments, he discovered that objects fall with uniform acceleration.
Galileo was fascinated by the behavior of falling objects. He knew that falling objects increase their speed as they go down. This change in speed is acceleration. However, he did not have any equipment to measure this change, so he used inclined planes to lessen the acceleration of the moving bodies. He was then able to investigate the moving bodies carefully.
On his experiment, he had observed the following:
A ball rolling down an inclined plane increases its speed by the same value after every second. For example, the speed of a rolling ball was found to increase by 2 m/s every second. This means that the rolling ball would have the following speeds for every given second.
wordpress
As the inclined plane becomes steeper, the acceleration of the rolling ball increases.
The maximum acceleration of the rolling ball was reached when the inclined plane was positioned vertically as if the ball is simply falling
These observations lead Galileo to conclude that regardless of the mass of objects and air resistance, falling objects would always have uniform acceleration.✔
