Why light and heavier object when fall through vacuum more side by side?

This is because the weight of an object does not affect the acceleration of that object due to gravity. At Earth's surface, the acceleration due to gravity is roughly 9.8m/s2, regardless of the mass of the object.
What does differ with the mass of the object is the force of gravity. Force is equal to mass multiplied by acceleration. So a one kilogram object will fall with a force of roughly 9.8 meters squared per second squared, or 9.8 Newtons (N). A two kilogram object would fall with a force of about 19.6N (2kg * 9.8m/s2). This is why when -NOT- in a vacuum, items of different mass can fall at different rates. The additional force of the more massive object will better counter the force of friction with the air, allowing it to fall faster even though it's acceleration is the same.

How does the speed of light in glass compare to the speed of light in a vacuum?
It will depend on the type of glass, and something called its refractive index. All materials have a refractive index which will effect the speed of the light through it. The speed of light through a vacuum is 3.0x10^8 m/s, and a material such as glass will be lower than this.
What is the speed of light as it travels through a vacuum?
299,792,458 meters (186,242 miles) per second.
Why is the speed of light a fact?
A "fact" is basically anything you can state, especially if such a statement is true. Since you can say "light has a speed", and since that is true, it follows that it's a fact. Light through a "vacuum" is the meaning of "the speed of light." Light through glass is slower.
Does a beam of light have a constant speed?
Light travels at a constant speed of 299,792,458 meters per second in a vacuum. However, as light travels through different mediums, it slows down depending on the medium. The crazy thing about light though, is that if it leaves a medium and starts travelling back through a vacuum, it once again goes 299,792,458 meters per second.
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
Why doesn't light travel through a vacuum?
Light does travel through a vacuum.
What evidence do we have that light travel through a vacuum?
You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.
Is vacuum a medium of light?
No, a vacuum is the absence of any medium, including air. Light can travel through a vacuum because it does not require a medium to propagate.
Can light travel through a vcuum?
Yes, light can travel through a vacuum because it does not require a medium to propagate. In a vacuum, there are no particles to scatter or absorb the light, allowing it to travel in a straight line indefinitely until it encounters an object.
What object does light travel through more slowly a vacuum water or glass?
Light travels very slowly in glass compared to water and vacuum
Does light travel at its slowest speed when passing through a vacuum?
No, light is at its fastest in a vacuum.
What happens when light passes through vacuum?
it travels at c (speed of light in a vacuum)
Can gases travel through a vacuum?
No. Only light waves can travel through a vacuum.
What materials can light travel through faster than it travels through air?
Light can travel faster through a vacuum than through air. In a vacuum, light travels at its maximum speed of about 299,792 kilometers per second. This is because there are no particles in a vacuum to slow down the light's speed.
What is the path that light travels if it does not hit an object or travel through a new medium?
If light does not hit an object or travel through a new medium, it will continue to travel in a straight line indefinitely. This is known as propagation in free space or a vacuum.
What does light travel faster through?
Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.
What form of energy is not associated with particles of an object?
Electromagnetic radiation, such as light, is a form of energy that is not associated with particles of an object. It consists of waves of electric and magnetic fields that can travel through a vacuum.
