Virtual image and Virtual Object

Click For Summary
A virtual image is indeed the reflection seen in a mirror, but the term "virtual object" is less straightforward. In optics, a virtual image produced by one lens or mirror can serve as a virtual object for another lens or mirror in a system. However, the concept of a virtual object doesn't imply that such objects exist independently; it's more of a theoretical construct. The discussion also touches on virtual particles in quantum physics, which are temporary pairs of particles that appear and disappear in a vacuum. Overall, while virtual images are commonly understood, the notion of virtual objects is more complex and primarily relevant in optical systems.

so virtual image is my image on the mirror? If that was true, then what is a virtual object? (with examples please)

That phrase is not appropriate in conventional optics - unless you say that the virtual image from one lens / mirror can be regarded as a virtual object for the next lens / mirror in the chain. But that's only a form of words and doesn't imply that there are really 'virtual objects' anywhere. There's enough to worry about in Science, without exploring all combinations of words that could come to mind. :)
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
