The Electronvolt - A Level Physics

This video introduces and explains the Electronvolt for A Level Physics.

In everyday life we use the joule to measure energy. When we consider the energy of individual particles or photons, it is often more convenient to use a smaller unit: the electronvolt, eV.

ELECTRONVOLT DEFINITION: THE ENERGY GAINED BY AN ELECTRON ACCELERATING THROUGH A P.D. OF 1 VOLT

Thanks for watching,

OMG, I didn't know like how the electronvolt is the electronvolt, like how you work out the value, in other words proving it which makes it easier to understand. I love your videos sir, the way you explain it in detail makes everything seem clearer.

[spiritualfoxplays-tryhardp]

Hey man, after watching a few of your videos including young’s double slit, I must say you really made me understand physics better as you sound confident in your answers as well. So I just want to say thank you and have a great day, sir!

[BoredTAK]

Who’s bingeing these videos right before their exams

[abhishekbhattacharjee]

this helped me solve a lot of confusion, thanks fr the vid.

[xhibah]

so does that mean that an electronvolt is the same as the potential difference?

[that-guy]

this is kinda a random question but do you have a video on how to reduce uncertainty in any experiment. I have a feeling for the new specification they are going to put heavy emphasis on uncertainty in section c

[yktcmzc]

but i thought the charge of an electron is -1.6 x10 to the -19, so shouldn't an electron volt be negative?

[Username-wwcd]

Did you know your videos are used to teach physics on Up Learn? It's a paid subscription and when I did the free trial realised its your videos which we can get for free on yt

[davidgorelle]

Alright cool, good to know. But what does Pd stand for?

[adityamisra]

The teaching part went a bit too fast I kept on pausing. But I still understood some parts.

[aryanjain]

Since electron is gaining kinetic energy of 1eV won't it be losing equivalent amount of potential energy since Potential energy change would be equal to -1.6*10^-19 J so mechanical energy remains conserved

[MisterBinx]

I trust a guy with an accent teaching physics.

[hola-lwbi]

It would have been better if you had included all the units in the intermediary step starting at 1:40.

[muhammadalimusani]

When can you use KE=eV and when can you use KE=1/2mv^2?

[AlchemistOfNirnroot]

Have you done/ or know of videos which help with converting from kg ---> neVc^2 and vice versa? Where n can be M, G or T.

Your English is too fast I don't understand your topic
