Are my laptop specs too low to watch youtube videos?

[ABC1231]

I got a very basic laptop which I just use for browsing (facebook, twitter, news etc.)
Specs:
Intel Atom Processor 1.66GHz 512kb cache
1GB RAM
Ubuntu operation system

It's perfect for just browsing, basically its only purpose, but when I watch youtube videos it lags. I've tried letting the video buffer completely but it still lags. I've also tried setting the quality of the video to 240p but it still lags. When I watch a video like kahnacadamy it doesn't lag.

Does this have anything to do with my laptops specs or is it related to something else?
Do you know of a solution to this problem?

Update your flash player, those specs are more than enough for youtube.

This. I would also update java to be safe.

I've also had weird issues where a video driver on my laptop caused issues on anything that was driven by flash player. If Updating flash and java doesn't help give video drivers a try.
