Is it true that we see an object when light from our eyes hit that objects?

No, that's not true. It's the other way round - light from the object hits our eyes.
We see the light that enters our eye.

Do an opaque object reflects the light that it does not absorb?
true
What does the wavelength of light tell us about an objects movement?
Assuming the object's moving rapidly enough to affect the light from it observedly: If approaching the light will be biased to blue (higher-f, lower wavelength); If receding, the light will be redder (red-shift), or lower-f, longer wavelength) by Doppler effect. If the true spectrum can be determined then the shift either way can be used to calculate the object's speed relative to the observer (not necessarily its true speed!).
Is the following sentence true 'unbalanced forces acting on an object will change the objects velocity'?
Yes
If you know the objects mass and acceleration you can determine the net force being exerted on the object?
True
Is it true that all atoms in objects are moving even if the object is still?
yep it's true. The atoms in a still object just move a lot faster and are closer together but they're moving
The methods of an object are the operations that can be performed on that objects data true or false?
True.
Which of newtons law implies that it takes more force to accelerate a havy object than a light object?
Newton's law doesn't say anything about heavy and light. The 'law' talks in terms ofthe mass of the object, and it's true even in space, where the objects have no weightat all.
Is it true that you see an object when light from it hits your eyes?
Yes, that is correct. Please note that the object itself doesnt create the light - it mearly relfects the ambient light (which, for example, comes from light blubs or the sun). It is this reflected light that the eye picks up and - with help from the brain - interprets into an image which we "see".
Why in poor light you cant percieve the true colours of objects?
Our eyes have both black-and-white receptors, and color receptors. The black-and-white receptors work at low light levels; the color recepters require a higher light intensity.
Does an opaque object reflect the light it does not absorb?
true
Do an opaque object reflects the light that it does not absorb?
true
Is it true that the color an object appears to be is the color of light that is absorbs?
NO it is not true an OBJECT appears colour because it reflect that colour
When you look at the night sky what is true of most of the light-producing objects you see?
For almost all of the objects you see in the night sky, the light that enters your eye left the object many years ago.The only exceptions are the moon, planets, meteors, artificial satellites, airplanes, and the occasional comet.
