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.
The results will vary, depending on the specific situation.
-- 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.
A light object has less momentum than a heavy object. A light object would stop first.
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.
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 paper weight on a piece of paper. -- A car on an ant
yes, bot not faster than light
the light one
Other things being equal, yes - with the same force, you can make the light object rotate faster. The amount of force required to make an object rotate depend on the mass, the size, and the general shape of the object. And of course on the rotational velocity you want to achieve. Do some reading on "moment of inertia" - for rotational motion, that is the equivalent of "mass" for linear motion.
cause the two have lost their weight
Because water is heavy, Air is light.
When you include the effects of friction, it takes less force to move a light-weight object. If you can get the objects into a frictionless environment, then any force, no matter how small, can move any object, no matter how heavy.
