What else can I help you with?
Would feather and a nail reach the ground at the same time?
No, a feather and a nail would not reach the ground at the same time if dropped at the same height in a vacuum. This is because the feather experiences more air resistance, slowing its fall compared to the nail which falls faster due to its higher mass.
Why will a feather and a hammer reach the ground at the same time if there is no air resistance?
The acceleration due to gravity is constant at the same elevation, therefore anything that is dropped from the same height here on Earth will accelerate at the same rate, and fall at the same time, hitting the ground at the same time.It is difficult to fathom this simply because we are used to observing the result of air resistance. You would need to perform this experiment in a vacuum.
What falls faster when dropped on the moon a hammer or a feather?
On the moon, both a hammer and a feather would fall at the same rate because there is no atmosphere to create air resistance. In a vacuum, all objects fall at the same rate regardless of their mass. This was famously demonstrated by astronaut David Scott during the Apollo 15 mission.
When You Drop An Object From A Certain Height It Takes Time T To Reach The Ground With No Air Resistance. If You Dropped It From Three Times That Height How Long Would It Take To Reach The Ground?
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.
Which has more kinetic energy a ball dropped from a height of 2m or a same ball dropped at 4m which has more kinetic energy just before it hits the ground?
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
If two object of different density are dropped simultaneously which one will hit the ground first?
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
On the Moon if a basketball and a feather are dropped from the same height about the ground which one hits first?
both reaches the ground at the same time because in the moon there occurs free fall.
If a hammer and feather were dropped simultaneously from the same height on the asteroid Ceres which would hit the ground first?
On the asteroid Ceres, both the hammer and feather would hit the ground at the same time due to the very low gravitational pull compared to Earth. This phenomenon is in line with Galileo's principle that objects of different mass will fall at the same rate in a vacuum.
Would feather and a nail reach the ground at the same time?
No, a feather and a nail would not reach the ground at the same time if dropped at the same height in a vacuum. This is because the feather experiences more air resistance, slowing its fall compared to the nail which falls faster due to its higher mass.

What will strike the surface of the moon first a hammer or a feather?
Answer 1:Both will strike at the same time. Gravity affects the descent of all things equally.On Earth, it would be the hammer. But that's because the feather has properties that will make it waft up due to air currents.There is no air on the moon.Answer 2:If a hammer and a feather are dropped simultaneously from a height on the moon they will hit the ground at the same instant.Leonardo DaVinci did this experiment with different weight iron balls on Earth to prove that objects fall at the same rate. He dropped them of the leaning Tower of Pisa.The reason a feather takes longer on Earth is because of the resistance of the air. In a vacuum everything falls at the same rate.Answer 3:"Both will hit the moon at the same time"This may not be absolutely true since every object has its own gravity which is greater if its mass is greater. So the hammer has a gravity much greater than that of the feather. Therefore the combined gravity of the hammer and that of the moon (which pulls the hammer and moon towards each other) is greater than that of the feather and the moon.As such the hammer should collide with the moon marginally earlier than that between the feather and the moon, though this difference is so minute that we assume that the collisions occur simultaneously.However, if the hammer and feather are dropped together, then as the hammer's gravity pulls the moon towards itself, it also pull the moon towards the feather and as such the lucky feather may get a free ride and hits the moon at the same time as the hammer.But even with this help, the feather will still take a slightly longer time to collide with the moon as the gravity from the hammer will cause the flight path of the feather to curve towards the hammer and as such takes a longer path and hence a longer time to hit the moon.To be fair, the experiment should be done dropping the feather first, then the hammer and then see the different times taken.All the above are valid only on the assumption that the centre of gravity is the part that hits the moon but since this is not true, we have to take into account the part of the hammer or feather which is nearest to the moon before the two objects were released !So, the real answer is that there is not enough data for us to know which will hit the moon first !
Which astronaut dropped a hammer and falcon feather while on the moon?
Apollo 15 astronaut Dave Scott dropped the hammer and feather to show that since there is no air friction on the moon, and the acceleration of an object by gravity does not depend on the mass of the object.The above experiment is supposed to prove the equivalence principle which states that the acceleration an object feels due to gravity does not depend on its mass, density, composition, colour or shape."Both will hit the moon at the same time?"Answer:If you drop a hammer and a feather from the same height on earth, the hammer will hit the ground first as the feather is slowed down drastically by air resistance.But on the moon, because it is a vacuum, and since the acceleration of an object is the same as the gravity i.e. a = g and the mass is not in the equation, all objects will have the same acceleration and hence the hammer should fall to the surface of moon at the same time as the feather but:"Both will hit the moon at the same time as believed by most scientists?"This may not be absolutely true since every object has its own gravity which is greater if its mass is greater. So the hammer has a gravity much greater than that of the feather. Therefore the combined gravity of the hammer and that of the moon (which pulls the hammer and moon towards each other) is greater than that of the feather and the moon.As such the hammer should collide with the moon marginally earlier than that between the feather and the moon, though this difference is so minute that we assume that the collisions occur simultaneously.However, if the hammer and feather are dropped together, then as the hammer's gravity pulls the moon towards itself, it also pull the moon towards the feather and as such the lucky feather may get a free ride and hits the moon at the same time as the hammer.To be fair, the experiment should be done dropping the objects individually e.g. feather first, then the hammer and then see whether the times taken are the same or not.All the above are valid only on the assumption that the centre of gravity is the part that hits the moon but since this is not necessarily true, we also have to take into account which part of the hammer or feather is nearest to the moon before the two objects were released (assuming that the centre of gravity of both objects are at the same level on release) !The real answer is that there is not enough data for us to know which will hit the moon first !
If there were no air resistance how did the speeds of a feather and a penny compare?
If there was no air resistance and a feather and a penny were dropped from the same height they would both pick up speed by the same amount and they would hit the ground at the same speed and at the same time.

Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
A feather and a rock dropped at the same time from the same height would land at the same time when dropped by?
They wouldn't land at the same time. the rock will land first and quickly because a rock have bigger mass than a feather. A feather is very light, if you ever tried to drop it from some height you could see that it takes very long time to land and it might go away to another place too.
