Hi guys, at 24:52 the fraction should be p1/T1=p2/T2. If you have spotted this, you have passed the test : )

@niclawrenson1906 Год назад

@Zphysics can you please explain this? P/T = nR/V which is not constant for an isobaric change, because volume will be changing, and nR is constant. I don’t get your correction i thought you were right in the video?

@saulneedham1333 Год назад

@@niclawrenson1906 pV = nRT, p/T = nR/V, p/T = constant, p1/T1 = p2/T2

@parth1705 2 года назад

For the Compression stroke of the 4 stroke engine you said that the spark causes the 'pressure and volume to increase dramatically at a constant volume', I think you meant to say the pressure and temperature increase at a constant volume

@zhelyo_physics 2 года назад

Absolutely correct, thanks!

@_Anti_Communist_ Год назад

I can't seem to find the various formulas for the moment of inertia on the AQA formula sheet? Also, just a quick question, what happens to the rotational kinetic energy when we increase the radius of the flywheel?

@zhelyo_physics Год назад

If needed, they would be given in the question, very often as a number too. You have the general ones given. And in terms of the fly wheel, as rotational KE=Iw^2 and I is proportional to r^2 so if everything else is constant, the KE will increase by a factor of r^2. Hope this helps!

@_Anti_Communist_ Год назад

@@zhelyo_physics Alright thanks, so I understand that increasing: Mass, Angular Speed, Amount of Spokes and Radius all increase this store of Rotational Kinetic Energy?

@fahrenheit2101 Год назад

Any tips for calculating areas quickly and accurately in an exam? Counting squares is impossible, and i never know how many trapezia are enough

@zhelyo_physics Год назад

if it's a multiple choice you can approximate with a shape and find the closest answer. If it's a numerical answer I am afraid counting squares might be the only option. How I wish integration was on the spec and then you wouldn't have to count squares : )

@rokerlegend6137 2 года назад

13:45 why does the KE stored increase with spokes?

@zhelyo_physics 2 года назад

I was thinking about researching this further, I think a spoked wheel of the same mass will have a larger radius, meaning that the mass will be spinning with a higher r of rotation, hence higher moment of inertia and more energy.

@rokerlegend6137 2 года назад

@@zhelyo_physics thanks

@daisybrown4995 2 года назад

The distribution of mass has changed (and therefore the radius) causing the I to increase therefore KE increases :)

@@zhelyo_physics I'm sadly going to have to cram for this physics paper 3 since I still have alot to cover and not exactly the most amount of time lol, any tips?

@zhelyo_physics 2 года назад

use the time wisely, make notes, run through the video and also look at the syllabus at the same time. You can do it! Don't forget to get a decent amount of sleep before the exam.
