According to my Physics 11 textbook, linear magnification is "the ratio of the size of an image to the size of the object". I'm not so sure about the term "magnifying power". WDJr seems to be correct: "The angular size of the virtual image seen by the observer will be larger than the actual...

D'oh! g = G*m/r² where G is a constant, and m is a constant for a given body (at least in classical physics). So acceleration is proportional to 1/r². But wait... that still doesn't describe the object's motion with respect to time. If I have an object, (for example, with a mass of 1 kg...

I'm a grade 11 student (I haven't formally learned calculus yet, but I've been dabbling with online tutorials) with a question (not for homework, just something I've been thinking about). For relatively small distances from Earth, we can estimate that the acceleration of a falling object will be...

So has anybody actually solved this yet?
