An astronaut drops a feather from 1.2m above the surface of the moon If the acceleration of gravity of the moon is 1.62ms2 down how long does it take the feather to hit the surface?
s = ut + ½ a t^2 1.2 = 0 + (0.5)(1.62)(t2) t = (1.2/0.81)1/2 t = 1.217 seconds
What is the surface gravity on earth?
The force of gravity on the earth is 9.8 m/s^2
How weak is the gravity on mercury?
The acceleration of gravity on the surface of Mercury, and therefore the weight of any mass located there, is roughly 37.7% of what it is on Earth's surface.
How does the force due to gravity on Mars compare to the force due to gravity on Earth?
The acceleration of gravity at the surface of Mars is approximately 3.7 m/s2. Earth's acceleration is 9.8 m/s2 on average. The force that gravity would exert on an object is dependent on its mass.
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 !

What is makemakes gravity compared to earths gravity?
The acceleration of gravity at its surface is currently estimated as 0.4 m/s2 .That's about 4% of the acceleration of gravity on the Earth's surface.
Is there gravity between the moon and an astronaut who is on the moon?
Yes. The moon's surface gravity is about 1/6 what it is on Earth.
Why is the acceleration due to gravity on the surface of Mars is about one third the acceleration due to gravity on earths surface?
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
What is the percentage of the acceleration due to gravity between the surface?
its 13.6
The acceleration of gravity on the surface of a planet will effect a person or objects?
The acceleration affects the weight of the person and object
The acceleration of gravity on the surface of a planet will effect a person's or object's what?
weight
What is the force of acceleration do to gravity on Earth?
The acceleration due to gravity on or near the Earth's surface is about 9.81 meters per second2 . The forces of gravity between the Earth and a mass on or near the surface are 9.81 newtons per kilogram in each direction.
What is the surface gravity on earth?
The force of gravity on the earth is 9.8 m/s^2
How weak is the gravity on mercury?
The acceleration of gravity on the surface of Mercury, and therefore the weight of any mass located there, is roughly 37.7% of what it is on Earth's surface.
How much more is the level of gravity on jupiter than on earth?
The acceleration of gravity at the 'surface' of Jupiter is 2.639 times its value at the Earth's surface.
What is the gravity related to earth of Venus?
On the surface of Venus, the acceleration of gravity, and therefore the weight of any object, is 90.3 percent of what it is on the surface of Earth.
