Galileo Galilei found out
Without air resistance, heavier and lighter object fall at the same speed. More precisely, they accelerate at the same speed - near Earth's surface that would be 9.8 meters/second2. If air resistance is significant, heavier objects tend to have less air resistance, compared to their weight, so they will usually fall faster.
As common sense would suggest, it is easier for them to lift light objects.
The reason that the greeks might not have had any questions to the evidence that hevier objects fall faster than light objects is because they would be questioning statistics which is that heavier objects and lighter objects do not fall at different rates but at the same its just the pending on the weight ex. a brick and a feather you drop a brick it falls quick beacuse of its weight and a feather because of it's weight it falls alot slower but at the measuerment of the objects falling quicker than the other they don't its irrelevent.
The wind and the temperature of the water makes it move, and the heavier it is the faster it moves.
the answer is no; the speed of light is the universal speed limit, nothing travels faster
-- Because that's the way gravity behaves. -- Because is would be ridiculous to think that heavy objects fall faster. Here's why: ==> Let's say that heavy objects fall faster and light objects fall slower. ==> Take a piece of sticky tape and stick a light object onto the back of a heavy object. Then drop them together off of a roof. ==> The light object tries to fall slower and holds back, and the heavy object tries to fall faster and pulls forward. So when they're stuck together, they fall at some in-between speed. ==> But wait! When they're stuck together they weigh more than the heavy object alone. So how can a stuck-together object that's heavier than the heavy object alone fall at a speed that's slower than the heavy object alone ? ! ? Isn't that ridiculous ? There's no way that heavy objects can fall faster than light objects.
Yes, that is correct.
So far no one has found anything to be faster than light. Some have sugested that ones thoughts may come up to being the nearest.
I am not sure what you mean; sound (in air) is actually roughly a million times SLOWER than light.
Here's the answer, and I love it. Let's assume that heavy objects fall fasterand light objects fall slower, just like everybody wants them to.Follow me now . . .-- Heavier objects fall faster. Lighter objects fall slower.-- Take a heavy object and a light object up to the roof of a tall building.Then take a piece of sticky tape, and stick the light object onto the backof the heavy one. Then walk carefully to the edge of the roof, and dropthe package over the side. As you do that, yell down "Look out below!"-- The heavier object normally falls faster, so it tries to pull the package ahead.The lighter object normally falls slower, so it tries to hold the package back. Soas they fight each other, the package falls at some middle speed, slower thanthe heavy object alone, and faster than the lighter object alone.-- But wait! They're taped together. How is that different from being glued together ?Or melted together ? Or welded together ? Or even inside the same skin ?-- Or even being the same single object ? They could just as well be a single object,one that weighs a little more than the original heavier object.-- But we just agreed that the package falls a little slower than the original heavier object,even though it's heavier than the original heavier object.-- Our orignal assumption . . . that a heavy object falls faster than a lght object . . . leads usdown the garden path to a ridiculous result.That assumption must be wrong.Don't ya just love it !
The best way to answer that question is: Because that's the way gravity works. When you think about it, it's really the only way that makes sense. Let's assume that heavy things fall faster, and light things fall slower. Take a heavy thing and a light thing. Tie them together with 3 feet of string, and drop them from a high building. The light thing wants to fall slower, and it holds the heavy thing back. The heavy thing wants to fall faster, and it pulls the light thing ahead. Together, they fall at some speed faster than the light thing alone, but slower than the heavy thing alone. Bu that's crazy. What difference does it make whether they're tied together with string, stuffed in the same bag together, or hooked together with nuts and bolts ? Together, they're even heavier than the heavier thing, but we just said that they're falling slower than the heavier thing would fall alone. It doesn't add up. Heavier things don't fall faster.
No one answer to your question. I shoot light .243 bullets for groundhogs, heavier bullets for deer. All other things being equal, the lighter bullet can be driven faster, but the heavier bullet will retain energy at long range better.
