At what condition does coin and feather fall together?

When there is no air resistance, a coin and a feather fall together. Acceleration of the feather and a coin at that instant is 9.8 m/s2.

Why does a feather and a coin fall at different rates?

Larger objects experience more air resistance than smaller objects. Since the feather is so much lighter than the coin, the air resistance on it very quickly builds up to equal the pull of gravity. After that, the feather gains no more speed, but just drifts slowly downward.

What is the conclusion of the coin and feather experiment?

The main conclusion of feather and coin experiment is that the falling rate or acceleration due to gravity is independent of the masses of the falling bodies. If there is no air resistance than all the bodies fall together irrespective of their masses.

When a feather and a coin are dropped in a vacuum tube?

The free fall of a coin and feather are compared, first in a tube full of air and then in a vacuum. With air resistance, the feathers fall more slowly. In a vacuum, the objects fall at the same rate independent of their respective masses.

In which condition does an object fall freely?

free-fall, in mechanics, state of a body that moves freely in any manner in the presence of gravity. The planets, for example, are in free-fall in the gravitational field of the Sun. Newton’s laws show that a body in free-fall follows an orbit such that the sum of the gravitational and inertial forces equals zero.

Why an iron ball and a feather fall together in vacuum?

In explaining Einstein’s theory, Cox said, “The reason the bowling ball and the feather fall together is because they’re not falling. “(Einstein) reasoned that if you couldn’t see the background, there would be no of knowing that the ball and the feathers were accelerating toward the Earth.”

What happens when an object falls freely in a vacuum?

Free Falling Object Motion. An object that falls through a vacuum is subjected to only one external force, the gravitational force, expressed as the weight of the object. The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth.

What is feather and coin experiment?

The “Coin and Feather” experiment is one of the best ways to dispel the “lighter objects fall more slowly” myth. The syringe vacuum pump (included) will bring the air inside the tube down to about 7\% of atmospheric pressure, making the feather and the coin appear to drop at the same rate.

Why does a hammer hit the ground before a feather?

Surprising as it might seem, an object’s mass has no impact on how fast it falls. Gravity accelerates both objects at the same rate, but another factor comes into play: air resistance. The feather is slowed down more by the air and floats down gently, while the hammer crashes straight to the ground.

What are the two conditions for free fall?

Two conditions for free fall:

• the resistance of air should be neglected.
• all object should fall with the same rate of acceleration, regardless of their mass.
