@lightningtiger090 How did you guess?

this is great, studying 4 my exams with these vids, great job!!

[hacksign000]

thanks !

[sarah29172]

cute videos... great way to understand the concepts!!!

@Punkyjes194 no meter persecond per second means meter per second squared, which is acceleration

These videos really help me somewhat prepare for my End of Year Examinations.

@roughrideres99 Accelleration is related to speed and time. Speed is measured in metres per second. Time is measured in seconds. Thus, accelleration requires two things to be measured with seconds: speed and time, so we represent it m/s^2, because one second is not longer than another second, so the second would be multiplied by itself, or squared.

@Kandecid i don't understand the meaning of m/s^2,, why is second square and not only second? thank.

[Punkyjes194]

But wouldnt Meter per second be the same as saying Meter per second per second?

I don't know if you still care to hear the answer. Anyway, gravity is 10m/(s^2).

The train in this example was 1m/(s^2).

But if hypothetically the train was accelerating at 10m/(s^2) and it KEPT accelerating that way (Remember: The top speed of the train is 36km/h in this example or 10m/s) then it would indeed travel as fast as an apple in a vacuum. In fact I don't even believe it would stop at it's terminal velocity because terminal velocity requires friction. : )
