    Physics Depth Study Advanced Mechanics

    Hi, I just got my first year 12 assignment which is a depth study of advanced mechanics. I had one idea of investigating the motion of rockets and satellites. I could even do something with circular motion or projectile motion, taking air resistance into consideration. I just don't what to do or...

    Types of lens flare - light and optical depth?

    I'm trying to understand what's going on with lens flare in different kinds of lenses. There's a lot of lens flare out there creating weird and wonderful artifacts in people's pictures. Without understanding the kind of lens flare going on in a very flat lens (e.g. smartphone) or a long lens...

    Pressure at a certain depth is the same on all sides of the object?

    Assuming that the object's surface is at the same depth, for example an object that is a line ----, why is there an equal pressure on the underside of the line? I know that at the top of the line, the perpendicular force is due to the weight of the mass of the liquid. Is the perpendicular...

    Perceived Depth

    I am looking down from my raft at a shark. Since I do not know anything about optics, I think the shark is somewhere along the line BD. Where do I 'think' it is along the line though and why? Thanks
