  • Decades ago, US astronauts proved that a hammer and a feather fall at the same rate, on the Moon.

  • These guys are funny. But seriously, who doesn't realise that air resistance means a pillow won't fall as fast at the cooker over such a fall? Same for the balls, it would've been a far great difference if they had of used a ballon and a cannon ball :-)

  • The theory of gravity and velocities require a vacuum. Two heavy cannon balls, different mass but the exact same materials and shape, will result in a nearly identical impact.

  • so heavy does an object have to be to cancel out the air density ,,,??why did the wheel and car fall at the same speed but the pther objects differed?

  • @uuber666 actually, wind is a vector quantity that acts parallel to the horizontal of the force, since the horizontal and vertical components of forces are independent of one another in trajectory, the wind speed and direction don't effect the decent of the object. air density and terminal velocity are closely related and would be calculated at the same time whilst taking air resistance into account.

  • wind resistance..

  • Wind resistance.

  • @GB016768 :D

  • @bosaap10 lol

  • @69aussieguy

    To say something like this is soley based on air resistance is naive, you have to take other things into consideration, wind speed, wind direction, air density and terminal velocity, to name a few.

  • 4:30 In your Face Aristoteles =D

  • @xXEnZeR0Xx that has to do with air ...in a vacuum , 2 objects will keep accelerating as they fall .
