Who is Faster? - An Experiment on Gravity and Falling Speed | C4D4U
HTML-код
- Опубликовано: 12 апр 2024
- In this exciting experiment, we pose the question: "Who is faster?" as we let two balls of different sizes, but the same density, fall freely. Find out if the size of a ball affects its falling speed and discover how gravity works in practice.
What You Will Learn:
The basics of free fall and gravitational acceleration.
The effects of size and mass on falling speed under ideal conditions.
Observe how objects of different sizes fall in Earth's gravitational field.
Discuss with Us!
Did you expect size differences to have an impact? Why or why not? Share your thoughts and knowledge in the comments!
Newton's First Law (Law of Inertia):
This law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force. In the context of your experiment, this means that the balls would continue to fall unless the force of gravity accelerates them.
Newton's Second Law (Law of Motion):
This law describes the relationship between the force applied to an object, its mass, and the resulting acceleration:
F=ma.
For objects falling under gravity, the acceleration is considered constant (approximately 9.81 m/s² on Earth), regardless of the object's mass.
Newton's Third Law (Action-Reaction Law):
For every action, there is an equal and opposite reaction. This is less directly relevant to free falling but comes into play when considering the interactions between the balls and the Earth.
Galileo Galilei's Laws of Falling:
Galileo demonstrated through experiments that all objects fall at the same rate in a vacuum, regardless of their mass. This debunked the older view that heavier objects fall faster.
His famous experiment at the Leaning Tower of Pisa showed that balls of different weights hit the ground simultaneously when the influence of air resistance is minimal.
Air Resistance and its Effects:
Air resistance is a force that acts opposite to the direction of movement of an object and increases with the object's speed and cross-sectional area. In your experiment with a short drop distance, air resistance is negligible, but it's important to understand how this factor plays a role at higher speeds or larger drop heights.
Conservation of Energy:
The laws of conservation of energy, particularly the transformation of potential energy into kinetic energy during a fall, are central to understanding how objects accelerate as they fall.

In the last few months I have had to report several hundred copyright infringements.
There are already so many people who have no ideas of their own and create exactly the same content (really absolutely identical content incl. objects, titles, descriptions).

All take, none give back.
This is really very sad and of course makes me sad.

MUSIC-MODE ;)
Why don't I enter the music title anymore.
Well, unfortunately some people not only copy my animations (because they have no ideas of their own) but even use exactly the same music.
These people may now search for it themselves ;)
I hope for your understanding.

0:17 is when the video actually starts
:)
Equal
05:15 this is the most interesting part of the video
😂 The video is only 54 seconds long 😂
Big one.
Oh... apparently there was no air or the had the same mass..
Still really cool video ❤
Thank you Curacaogirl :)
The air resistance can be neglected at such a short distance. Both have different masses but the same density. Both arrive at the same time.
The video should be physically correct even if it does not take place in a vacuum.
@@C4D4U ohhh yes of course!! I forgot that for a second 🤭
@@curacaogirl Ha ha ha, no problem.
Equal 😂
The description got me rolling LMAO:
“Если вы хотите поддержать меня, не стесняйтесь купить мне кофе.” смех! this is so funny
Let me give you a sentence
C4D4U, мне нравятся все твои видео. Можете ли вы сделать больше видео? Я сохраняю ваши видео в плейлист, чтобы пересмотреть их.
Из rc5 для C4D4U.
I think I rogured it out. Gravitational acceleration does not depend on the mass. Hence, due to greater resistance (friction), the ball accelerated more slowly in the pr3vious video.
Yes, you're right about gravity. In the previous video, it is the moment of inertia that is decisive. The resistance to rotation.
Highway: a main road, especially one connecting major towns or cities.
Wie jetzt? Keine Reibung mit der Luft? Oder war der Fall-Weg nicht lang genug, damit die große schneller wird, als die kleine?
😂 Das klang jetzt widersprüchlich.
Sollte physikalisch korrekt sein. Luftwiderstand kann bei so einer kurzen Distanz vernachlässigt werden.
Galileo hat vom Turm in Pisa zwei Objekte fallen gelassen, mit unterschiedlicher Größe. Damit konnte er alte damals bekannte Ansichten widerlegen.
@@C4D4U I can speak 3 languages 👀
It's a tie!
?😂
I would say the big fall faster but as nobody would have asked if that was the case I'm saying none, they have the same mass
Edit and spoiler : I was right
Edit 2: I missed the "same density" thing but also forgot the fact gravity doesn't work the same way when it's free falling so I guess it's luck
Gravity is the decisive factor here ;)
