Well i think centripetal force is inversely proportional to the radius, so I'm guessing it would decrease but not sure to be honest.

Thank you so much for your reply, but I've decided to investigate the effect of radius on centripetal force using a conical pendulum. :)

Homework Statement: 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...

Would this be a good response?? The following investigation was valid as the experimental design tested the aim and all variables apart from those being investigated were kept tightly constant to stop them from affecting the results. The internal/criterion validity of this experiment was very...

oh sorry... It's assess. An example would be: Assess the validity of your experiment and suggest ways in which it can be improved. Attempt: The experiment was fairly valid as the experimental design tests the aim and all variables apart from those being investigated were kept constant...

Thanks for your help but how would I start my topic sentence in a scientific way? Is it something like The experiment was fairly valid...or The experiment was not valid... How do I write these in a scientific way?

Assess the validity of this experiment and suggest ways in which it can be improved. The experiment was fairly valid as the experimental design tested the aim and all variables apart from those being investigated were kept constant. Now you would elaborate on this statement through evidence, etc

I saw a couple of videos on how to build a simple 555 timer square wave generator, but it seems really complicated. I'm only in year 11 so I don't want to do something really complicated. Thank you so much for your help anyways :)

Is the 555 timer square wave generator hard to build? If you have any idea on how to build it, could you please explain that. Thanks

I'm sorry for not explaining it well but what I mean from a deep understanding of the theory is that I know how a change in the wave characteristics such as frequency, amplitude, velocity, and period/wavelength affect or change sound waves in terms of their loudness and pitch, but I don't know...

I have attached my physics notification. These are the instructions we were given. We can't use too high tech equipment as our school won't provide them.

I don't know how to make the practical or what practical I can conduct that would test the question we have been given.
