in a vacuum, items do items fall at the same rate?

Question

what about a piece of lint and a building? i know there is no air friction but does weight matter or mass??

Answer 1

yes .. in vacuum, all items will fall at same rate... it is the rate at which the gravity acceleration attacts everything to the center of teh Earth. But you might have a queation, that if the acceleration is same then why different things weigh different...

weight =mass X acceleration of gravity (9.8meter/second^2) and mass is the one which is a measure of matter in a body makes the difference... so if you let a 5kg weight and a 5,000kg weight fall in a vaccum, they will fall at the same rate and will reach the ground at the same time.

Answer 2

Provided you can release the building and lint exactly at the same time over the same gravitational field they will in theory fall at the same rate. That particular experiment has not been tried, but astronaut David Scott of the Apollo 15 mission did an experiment to prove it by dropping a feather and a hammer on the moon where there is essentially a vacuum.

Answer 3

Weight and mass make no difference until they hit the ground.... the lint fluff and the building would fall at the same rate, hit the ground at the same time, but the lint fall would go unnoticed while the building would make a lot of noise and probably a crater.

Answer 4

Ya you are right.Mass don't matter. A feather and a brick will fall at the same rate in a vacuum because there's no air resistance.

Answer 5

yes. weight/mass don't matter. A feather and a brick will fall at the same rate in a vacuum because there's no resistance.

Answer 6

properly, we in simple terms went over this in AP Physics: Acceleration of gravity= 9.80 m/s^2 (a million g) Acceleration= a speed= V (speed) Delta= "replace in" or Displacement Time=t a= delta v/ delta t therefore, the acceleration equals the replace in speed divided through the replace in time. for instance, if a motor vehicle hurries up from 20 m/s to 35 m/s in 12 seconds (s), what's that is average acceleration? the answer: 35-20= 15= delta V= replace in speed 12 s= delta t= replace in time (in seconds) 15 m/s divided through 12 seconds = a million.25 m/s^2= average acceleration therefore, in a vacuum (with out air) all products will fall on an same fee. even if, contained in the actual international (with air resistance)- in case you dropped some thing off a ladder, the products with larger factors that were more effective in probability of air resistance would fall slower (or have a slower fee of acceleration). products that ought to fall slowly: - Piece of paper - Styrofoams - sea coast balls - Balloons - Blades of grass You get the perception... issues that ought to fall with a intense fee of acceleration: - Small metal balls - Hardback books - Rocks You get the perception... save in recommendations, the acceleration of gravity is a continuing 9.80 m/s^2, therefore all products fall on an same fee at the same time as neglecting air resistance. contained in the actual international products which have a huge floor section and are in probability of air resistance will fall slower.

Answer 7

No, once you eliminate air resistance, all objects are affected equally by gravity and fall at the same rate of acceleration, provided that they are on the same planet (same gravity field).

Answer 8

In a perfect vacum nothing falls, nothing moves unless acted upon by another force (ie Gravity.)

Answer 9

In a vaccum nothing would fall it would just stay in the same place if we presume that there are no other factors.

Answer 10

yup
