They would hit the surface together, after a very long time. Gravity on Ceres is pretty light.
Both the hammer and the feather will hit the lunar surface simultaneously. In the absence of any atmosphere, there is no air resistance to slow down the feather. Therefore, in a vacuum, all objects fall at the same rate regardless of their mass. This was famously demonstrated during the Apollo 15 mission in 1971 by astronaut David Scott, who dropped a hammer and a feather on the moon's surface and observed them falling together.
Since they are both headed toward the center of the moon at the same rate of acceleration they should hit the moons surface at the same moment. No air resistance to speak of allows this.
because there is no atmosphere .
Assuming that each object is held with its center of gravity at the same height, and that each is dropped cleanly, with no rotation induced, the one whose lowest part is closest to the ground when dropped will hit first.
4 seconds
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.
They will both hit the ground at the same time.
Gravity.
They would hit the ground at the same time, Galileo dropped to balls with different masses and they both hit the ground at the exact same time.
On Earth, no. Air resistance would slow the feather way down. However, dropped on somewhere without an atmosphere (like the moon), they would reach the ground at the same time.
both reaches the ground at the same time because in the moon there occurs free fall.
Purely air resistance, the feather floats on the air. The mass is irrelevant. If a penny was dropped at the same time as a brick (ignoring wind resistance) both would hit the ground at the same time. Look up Galileo's tower of Pisa experiment. http://en.wikipedia.org/wiki/Galileo%27s_Leaning_Tower_of_Pisa_experiment This also includes a video of a feather and a hammer being dropped on the moon (where there is no air). Both hit the ground together.
If you drop a feather on the moon, it will fall from your hand with an acceleration of 1.62 meters (5.32 feet) per second2, and never a ripple or a flutter. If you drop the feather and a stone at the same time, they hit the ground on the moon at the same time.
The football will hit the ground and probably stay there. The cricket ball will be caught before it hits the ground and used enthusiastically by the grateful kiddies.
They will hit the ground simultaneously. Gravitational pull is the same on all matter.
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.
In a vacuum, a feather and a hammer will hit the ground at the same time if released at the same moment. In normal air, a feather will take longer to reach the ground.
