Experimenting Mechanics: Two Balls, Same Time - Glilio Glili

AI Thread Summary
When two balls of different masses are dropped simultaneously, they hit the ground at the same time due to the uniform acceleration of gravity, which acts equally on all objects regardless of mass, assuming air resistance is negligible. This principle is rooted in Galileo's experiments, which illustrate that mass does not affect the rate of free fall. The discussion also touches on the concept that a ball thrown upwards reaches a maximum height where its velocity is zero before descending. Participants express interest in additional physics experiments that demonstrate similar principles. The conversation highlights fundamental concepts in mechanics that are essential for understanding motion and gravity.

I want to know why if I throw 2 balls and one ball is bigger and whit more mass
Why the two balls arrive to the ground in the same time
This is the experiment of glilio glili
Also I search after more experiment in mechanics (physics) like this
Or like this experiment - if I throw a ball up when the ball arrive to the maximum the velocity is zero
thanks

Welcome to the PF. Here is an discussion of Galileo's famous "experiment" (which most likely was a thought experiment, but there is debate about that):

The 2 objects fall at the same rate (neglecting air resistance) because they both experience the same acceleration due to gravity, which is independent of the object's mass.

To find you more examples of experiments, I just googled classic physics experiments. Here is the hit list:

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
