Weight has nothing to do with how fast things fall, only wind resistance. Take two 16 ounce soda bottles, open one drink eight ounces. The unopened bottle is twice as heavy as the opened bottle. Close the bottle you just drank half of and drop them at the same time from a tall building, they will hit the ground at the same time. That is because gravity is a constant and the velocity of any falling object is 9.8 meters per second/per second.

Acceleration is the same for all objects atm/s^2(32.2 ft/s^2 or 22 mph) for each second of its descent. Thus, ignoring air resistance an object starting from rest will attain a velocity of 9.81 m/s after one second, 19.62 m/s after two seconds, and so on.
Acceleration due to gravity near the earth's surface is the same for all objects regardless of their mass.
This is because acceleration is inversely proportional to mass:

a = F / m

If you substitute the "force of gravity" equation above for F in this simple equation, and assume m here is m1 there, you'll find you have m1 (mass of the falling object) on both sides of the fraction, so they cancel out - acceleration due to gravity doesn't change with the mass of the object. But the force most definitely does.

Force and acceleration are two very different things. Confusing them leads to wrong answers and f

Depends which direction the object is travelling in the water. If the object is on top of the water, the lighter object would be faster. If the object is sinking in the water, the heaver object would be faster.


They both fall at the same rate. This is because they are both only acted upon by one force in the vacuum- gravitational acceleration. The mass, size or shape of the object do not influence the object's motion in a vacuum.


It would depend on the shape of the light object, usually it is because of air resistance.


The results will vary, depending on the specific situation.


Simply put neither falls faster than the other. Weight has no bearing on how fast something falls Check related link for more information. Exactly. It's a common misconception that heavy things fall fasdter, but they don't.


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 !


A light object has less momentum than a heavy object. A light object would stop first.


-- 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.


light is reflected when it falls on some object. every object has the ability to reflect light.


When heavy objects roll down something, fricition is involved. Friction is made by the rubbing of one thing against the other. Try rubbing your hands together reallly fast. Do your hands feel warm? Heavy objects have more friction, which slows down the heavy object. Lighter objects have less friction which cause it to run faster.


I suspect that if they didn't, you'd ask why not.Heavy things and light things fall with the same acceleration because anything else would be absurd.Think about it. Let's say heavy things fall faster than light things, and let's see where that leads us, OK ?Take a heavy thing and a light thing. Tie them together with some length of light string, and drop them offthe roof of a tall building. What happens ?The heavy one wants to fall faster, and it pulls the light one down faster than the light one would normally fall.The light one wants to fall slower, and it holds the heavy one back, slower than the heavy one would normally fall.Together, they fall at some speed between the normal speed of the light one and the normal speed of the heavy one.But that's absurd. You have a combination of a light object and a heavy object. Together, they're heavier thanthe heavy object alone. But they're falling slower than the single heavy object alone would fall.


The reason is very simple. Heavier objects are harder to accelerate than lighter objects, even for gravity. So while a heavier object experiences more force than a lighter object, this cancels out with the greater force needed to achieve the same acceleration.The ancient Greeks knew objects had to fall at the same speed regardless of weight thanks to the following thought experiment:Assume heavier object fall faster than lighter objects. Now imagine a heavy object and a light object connected by a short string. The heavy object will try to fall faster, pulling down on the light object. The light object will try to fall more slowly, pulling up on the heavy object.When the string gets tight, they will have to fall at some intermediate speed with the heavy object at the bottom and the light object at the top. But now these two objects with the string are, together, an even heavier object. So mustn't they fall at a faster speed than even the heavy object?Both arguments are totally conclusive, yet they give opposite results. Thus our original assumption, that heavier things fall faster, must be false.


Black will be the color of a yellow object in a dark room while white light falls on it.


Green will be the color of a yellow object in a dark room while red light falls on it.


That refers to the object's weight.


It depends on how big and heavy it is. If it is large and heavy it falls fast, if it is small and light it falls show ************************************* Unfortunately, the above answer is not correct. Size and weight of a falling object (in a vacuum) have no effect on the Speed at which it falls. In "open air" the size and shape of an object WILL effect its "Wind Resistance" and can slow it down. For a person, like a Sky Diver, the terminal velocity is approximately 120 MPH. This is controlled by body position, Arms, and Legs.



opaque is a object in which light can't pass through it. so when light hits the object it casts the shadow.


no its not. since when light falls on the (object) it will create a shadow.


Not without the help of air resistance. With plenty of air resistance, a small, light, wadded-up sheet of paper could fall faster than a big, heavy sheet of lead foil. In the absence of air resistance, the size, age, weight, mass, shape, race, creed, color, religion, political persuasion, gender, or national origin of the object has no effect on how it falls. They all fall with exactly the same acceleration, and all reach the same speed in the same amount of time.


Black light is asborbed and white light is reflected


In the absence of other factors, such as air resistance, the weight of an object does not affect its rate of acceleration in a gravitational field.


-- A paper weight on a piece of paper. -- A car on an ant


Technically, if there are no specified resistive forces, any force applied will cause the object to accelerate and not slow down until another force is applied to it. But if there are resistive forces, the same force will generally accelerate a light object faster than a heavier one.


A shadow , a portion where there is absence of light.
