:confused: I'm still a little confused here, I'm just beginning physics and only know the basics of motion and things, its not the math that i can't work out its just the conceptual part, I mean I thought (so far) that acceleration was change in velocity divided by change in time. Although...

:confused: Hello I need some help understanding Newtons universal gravitation. I read on a site that an objects Force on Earth is its mass x gravity(on earth) hence MG (like F=MA). Then they say using Newtons inverse square law that the same object at a distance of the moon would have the...

Dimensions ------------------------------------------------------------------------- Ah very clear, I understand now, just breaking them down. Thanks

Hello I've been learning the basics of physics over the past few weeks and thought I knew what they meant when they would refer to the dimensions of something for instance if you asked me what are the dimensions of acceleration I'd say 'change in velocity/time'' or 'v2-v1/T' but I came across a...

Hello I'm learning physics and also brushing up on some math (its been 10yrs) and I encountered difficulty in understanding Dimensional analysis. I don't really understand how they know what number goes on top or what goes on bottom. I've read some explaintations but they just confused me...

I have read Zapperz's misconception of the Heisenberg uncertainty principle (and in magazines/books etc) and am still confused. What your saying when you describe how when the slit is made smaller the spread of the particles becomes increasingly spread out doesn't makes sense. So you say in...

ah, thank you that is a much better explanation. Heh I felt a bit of a dummy asking such a question but you got to start somewhere!.

Hello I'm a beginner in physics and came across an explanation for Gravitation, it explains it using the moons orbit around Earth as an example, they also say firing a projectile at a certain velocity can put that projectile in orbit, but they confused me with that one, can anyone help? this is...
