How did Galileo experimentally confirm the hypothesis of the study of free fall?

Galileo discovered that the acceleration of bodies sliding off a smooth inclined plane depends on its angle. The greater the angle of inclination, the greater the acceleration of the ball. From this he concluded that this provision is also true for free fall.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
