In a vaccum:- the body accelerates in a free fall for 9.8m/s^2. A vacuum has no air-resistance, only gravitational pull acts on it With air:- the body accelerates in a free fall for 9.8m/s^2. However, for larger/less aerodynamic objects eg:- an elephant, air resistance can reduce the acceleration of the object leading to terminal velocity, where both drag and gravitational pull is equal in other words the thing that makes the velocity increase/decrease is air-resistance in a falling object. In the video it shows well a ball of different mass is dropped from a height, which is a freefall. Hence, No matter if its a vacum or not, the acceleration will be 9.8m/s^2, if terminal velocity is not reached!!
Suppose u r standing in the middle of the road, on both sides exactly at 1 km away, two group of bikers are standing, one groupe has 10 bikes in it, and 2nd group has 50 bikes in it, all bikes have same engine, same acceleration and same maximum speed, when you signal both the groups, they start moving towards you at the same time, because both groups have same speed, they will reach u exactly the same time, now you say 1st group was smaller it had 10 bikes only, and 2nd group had 50 bikes, why didn't 2nd group reached you faster? Same is the case with lighter and heavier object, both objects are made up of exactly same type of sub atomic particles, they all have same mass, the only difference is heavier object has more such particles and lighter object has less of such particles. The earth attracts all the subatomic particles with same force and all individual particles move at same speed. That's why objects with more electrons, protons, neutrons and objects with less electrons, protons, neutrons reach earth on same time. This is ofcourse in vacuum where air resistance is ignored.
But how it came true in the experiment done by Galileo Gailele from leaning tower of Pisa although it doesn't have vacuum when he drops two balls of different masses say M and m thus due to air resistance the ball with mass m i.e the lighter mass should reach slowly then heavier mass M.. Do u have any explanation regarding this?
@@darshnyadav5002 explanation is the same, the sub atomic particles of both the masses M and m (even if they are made up of different element e.g: carbon and iron) have exactly the same masses, but they are different in numbers, all the sub atomic particles having equal masses will be attracted by the earth (=sub-atomic particles that constitute the earth) with equal velocity, hence they cover the same distance in same time.
This video is wrong in Earth heavier object will fall down faster than lighter object due to air resistance.Like the feather and a stone.But without air resistance lighter and heavier object will fall down in same speed and together.
Even in vacuum heavier objects will hit the ground sooner. With small objects the difference is more than negligible, but if you take something with mass comparable to that of the Earth's, you will notice it will hit the Earth much faster. That's because gravity is at least two forces. It's not just the Earth attracting you, but also you attracting the Earth. Now, you're light so you can ignore it and it won't matter at all, but a heavy object, like a huge asteroid, or another planet, will make a difference in the speed of falling and will hit the ground faster.
Galileo's purported experiment only works perfectly in a vacuum, and only works approximately well at low heights through air. Even with identical surface material and areas giving the same air resistance, more massive bodies falling through air have a higher terminal velocity and will hit first, though you may be unlikely to notice it for a couple of reasons: 1) you're dropping it from too low of a height for velocity to accrue, or 2) you're inadvertently dropping the light body sooner than the heavy body and this cancels out its delayed impact (and one argument for the reality of some form of Galileo's experiment is that he noticed that lighter things tend to be released earlier by the same person's hands). If you multiply the height of Galileo's experimental tower by several times, and use a device to release things simultaneously, you will begin to notice the significant delay of impact of the lighter body. So Galileo helped clarify and formalize -- but cannot be said to have completely repudiated -- the "common sense" earlier view that heavier things do, on Earth, fall faster than lighter ones (again, due to air resistance differences from size and shape, and velocity differences from mass). I feel like physics teachers often bypass this nuance in their explanations.
Assuming there is no air resistance too. Also, inertia is key. The "heavier" item has more inertia and hence is sluggish. It's like making a heavy car accelerate
It is independent of nature of mass and as we know when object fall their gravitaional potential energy is converted into kinetic energy =½mv² and it is proportional to mass and square of speed Mgh=½mv²and divide m on both side and 2 to cut fraction and thus v²=2gh and thus proved
Let an object has mass M. And gravity attracts it with a Force F. We know F = MA So A = F/M Now, if we double the mass of that object to 2M the gravitational force acting on it will be doubled so 2F. 2F = 2M a So a = 2F/2M =F/M So a = A The acceleration due to gravity is independent of the mass of objects. There is a comment saying the heavier ball will fall faster than a helium balloon due to more density but it has nothing to do with density. It is an external thing. They both accelerate at the same rate. We couldn't say the heavier ball will reach the ground fisrt because a little kid throws the balloon back to air.
this is wrong, as much the experiment show that it might fool a lot of people. they will only fall at the same speed till one of then the reach terminal velocity. 2 equal objects with different mass will have different terminal velocities. the trick here is to find an object that reaches terminal velocity before it hits the ground, and then compare to other object with the same shape but heavier.
This is false because the sizes of these objects are too similar. Gravity is directly proportional to the mass of the objects that fall. We need the sizes to be greater to see a difference. Air resistance is important as is water resistance but in space large planets will accelerate slower and reach higher speeds than smaller items like individual molecules of gas.
exactly, its not a free-fall, the paper reached 'terminal velocity', due to air-resistance (bc of it's surface area & mass) the only force acting on the book is gravitational pull/weight, meaning its a free fall.
@ACanadianFry aren't we taught that the mass doesn't affect the gravity affected on it... so the earth would pull 1kg object the same as the 2kg object but the only diffrence is the objects mass which affects the objects gravity.
the heavier object will always fall faster if its given enough distance to reach its maximum velocity ... if you drop 2 objects inside a vaccum the heavier item will still fall faster if giving enough distance to reach maximum velocity .... all a vaccum does is remove the air so their is no resistance ...
@@Asifkabeer no its the density of the object ... if an object is denser than the medium its travelling through it will fall down ... if an object is less dense it will rise up... example... 5kg bowling ball and 5kg helium balloon released from 10mtrs .... which will hit the ground 1st and why.... density.... 👍

Two kilogrammes . Mass have a relation with gravity by newton second law .in space mass with a direct force gain speed 9.8 *mass minus resistance.
That was awesome! And it was something new for me👍🏻👍🏻

Wouldn't air resistance affect the lighter body more? Maybe in a vacuum the two weights would fall at exactly the same time?
Air resistance has a relatively lesser force than gravity.
@@Asifkabeer So, feather vs. canon ball?

If its falling without air resistance theyd both have the exact same acceleration.

Thanks Sir
Let an object has mass M. And gravity attracts it with a Force F.
We know F = MA
So A = F/M
Now, if we double the mass of that object to 2M the gravitational force acting on it will be doubled so 2F.
2F = 2M a
So a = 2F/2M =F/M
So a = A
The acceleration due to gravity is independent of the mass of objects.

That doesn't make sense! Helium balloons dont fall, precisely because they are less dense than air. Am I right?
@@MisterDenisTTyou are right. Some people just deny common sense to believe some madeup numbers lmao.
I thought the heavier the object, the faster it will fall. Like the equation p = mv

Interesting! Thanks for sharing!
Thats genius. Thank you for the nerd variant :D
Show the Apollo Moon HAMMER/FEATHER experiment and explain that in relation to the Moon's 'gravity'.
The result was exactly as expected in 1/6 g and vacuum.
Is this experiment performed without air resistance?
That's the assumption
But what about mg
nice
this is wrong, as much the experiment show that it might fool a lot of people.
they will only fall at the same speed till one of then the reach terminal velocity.
2 equal objects with different mass will have different terminal velocities.

It's about terminal velocity
yh, this video shows freefall
bro at any height if you drop whether it both reaches same height ,max height these principle applicable
i just dropped a piece of paper and a book together but the book fell first while the paper was still in the air
exactly, its not a free-fall,
the paper reached 'terminal velocity', due to air-resistance (bc of it's surface area & mass)
the only force acting on the book is gravitational pull/weight, meaning its a free fall.
Bonjour, what is this
This is wrong. Aerodynamics (drag, parasitic drag etc) act on different shapes differently

But 2kg mass has more of its own gravitation pull than 1kg so would 2kg be so slightly faster
inertia causes 2kg to take more force to accelerate so it balances out

@@jamescaldwell8153 no, mass definitely causes the force of gravity to be stronger, which is why heavier things are harder to move?
