Relevant formulae:
weight = mass x gravity
force = mass x acceleration (Newton's Second Law)
Let's say, for the sake of argument, that one object has twice the mass of the other. For example, 2 kg versus 1 kg. The more massive object will be subject to twice the gravitational force - close to Earth's surface, that would be about 20 newton, compared to 10 newton for the less massive object. But the more massive object also has twice as much inertia; that is, twice the force divided by twice the mass will provide the same acceleration.
Light can travel through vacuum, but it is not a medium.
an objects light can pass through is transparent
As common sense would suggest, it is easier for them to lift light objects.
Light travels fastest through vacuum.
Dark objects do not reflect light. Light is absorbed by them.
Light does travel through a vacuum.
Light travels faster through a vacuum. Velocity does not change in a vacuum, so objects retain their original speed and direction unless acted upon by another force, like gravity.
Light can travel through vacuum, but it is not a medium.
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.

No, light is at its fastest in a vacuum.
it travels at c (speed of light in a vacuum)
No. Only light waves can travel through a vacuum.
sometimes it pass through objects
Light travels fastest through vacuum.
When the light is traveling through vacuum.
