What else can I help you with?
Are rocks and stones the same thing?
No, rocks and stones are not the same thing. Rocks are made up of one or more minerals, while stones are small pieces of rock.
In 1971 who dropped the hammer and feather on the moon to seen which would land first?
In 1971, astronaut David Scott dropped a hammer and a feather on the moon during the Apollo 15 mission to demonstrate Galileo's theory that objects of different mass would fall at the same rate in a vacuum. This experiment showed that in the absence of air resistance, the hammer and feather landed at the same time, supporting Galileo's prediction.
What would happen if you droped a hammer and a feather on the Moon?
What would happen if you dropped a hammer and a feather on the earth and on the moon? 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.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 !The famous experiment by Astronaut Dave Scott on the moon is not very precise.Dr HW Looi
Why do the three rock groups contain the same basic composition?
All rocks are some arrangement of Earth's magma. Igneous rocks are hardened magma. Sedimentary rock are from weathered material from igneous, sedimentary, or metamorphic rocks. Metamorphic rocks have the same composition but are subject to extreme heat and pressure and hence change their crystal structure.
Are stones and rocks the same thing?
No, stones and rocks are not the same thing. Rocks are naturally occurring solid aggregates of minerals, while stones are small pieces of rock that have been shaped or smoothed by natural processes like erosion or human activities.
What is heavier 100 pound of rocks or 100 pounds of feather?
Both 100 pounds of rocks and 100 pounds of feathers weigh the same amount, which is 100 pounds. Weight is a measure of the force of gravity acting on an object, and in this case, both sets of objects have the same weight. The difference lies in their densities, with rocks being much denser than feathers, which is why a smaller volume of rocks weighs the same as a larger volume of feathers.
Do all rocks weigh the same if they have a different mass but the same weight?
Do all rocks weigh the same if they have a different mass but the same weight? Let's look at the question without one bit of it..... "Do all rocks weigh the same if they have ......... .... ... the same weight?" If things are the same weight, then they weigh the same.
Is 20 pounds and 54kilograms the same thing?
No. 1 kilogrammes = 2.2046226 pounds, so 54 kilogrammes = 119.04962 pounds and 20 pounds = 9.0718474 kilogrammes
Which weight the most a pound of cheese a pound of bricks or a feather?
the same
Do all objects fall at the same seed?
Yes - If they have the same weight. No - if they are different weights... imagine dropping a feather and a stone.
What is the amount of matter or stuff in a body?
The amount of matter or stuff is measured by the mass, measured in kilogrammes and other units like grammes or pounds. It not the same as weight, which (if you are an astronaut) changes with where you are.
When two object have different weight falling from same height which will come first?
drop a brick and a feather at the same time.. u tell me
Could a bag of feathers have more mass than the same size bag of rocks?
If the two bags weighed the same then yes they would have the same mass! But If they had different weights then the mass would be different! and the mass of the rocks would be higher then the bag of feather!
What weight more then a pound a brick a pound of sheese or pound of feather?
it is a pound of everything. so all will have the same weight.
Under what conditions would a lead weight and a feather fall at the same rate?
If they were dropped in a container from which the air had been removed.
What conditions would a lead weight and feather fall at the same rate?
The lead weight and feather would fall at the same rate in a vacuum where there is no air resistance to slow them down. In the absence of air resistance, all objects experience the same acceleration due to gravity, regardless of their mass. This is demonstrated in Galileo's famous experiment at the Leaning Tower of Pisa.
Which is heavier a pound of feathers or a pound of rocks?
They both weigh the same. A POUND of feathers vs. a POUND of rocks. A pound is a pound, and whether it is a pound of feathers or a pound of rocks, it doesn't matter. It's still a pound. THINK ABOUT IT!
