Uniformly accelerated motion 2 [IB Physics SL/HL]

We're so excited to be able to share our exams with you!

Cheers, Mitch

such an optimistic teacher. THANK YOU FOR YOUR EFFORT!

really really like the way he's explaining the concepts!!!

hi! thank you so much for these videos. if I were to take down to be positive when using 9.81 as acceleration would that be ok to then have a positive acceleration and a positive displacement for the first example? and can I do this for other examples so long as I am careful and consistent? I think i prefer working with a positive acceleration of free fall !

1:40 don’t u take a positive side first then a negative side so u know what’s what

It's kind of confusing to label these videos '2.1, 2.2, 2.3...' because those are the sub-topic labels in the syllabus, but that's not what you mean it it? You just mean, part 1, part 2, part 3 of, possibly, the same sub topic!

1:40 i think this video's incorrect. -9.8 for acceleration means the acceleration is negative and the object is going upwards. because if it was +9.8 it would be acceleration due to gravity which happens towards the surface.

[rampranavnavendran]

Is it possible that we can take gravity as 10ms^-2, is using 10 not allowed in the IB?

[edward]

wouldn't -9.81m/s^-1 be deaccelerating?

[lux]

This doesn't work if you are "pushed". That will mean u is not 0.

I got a bit lost as to how you got 9.81 for acceleration. help???😟😬😬😬
