came for the revision left with knowing how to get ketchup out of the bottle correctly

@OSC1990 3 года назад

Hah, nice one. I do try to give interesting uses. Ketchup is important to life :)

I just wanna say that everything about the video is great...but if you could just use a more complex example it would be better because the questions aint always so easy just hope you can do that thanks

@oskarfurdyn9265 3 года назад

I just wanted to say that without your videos I would have jumped off a bridge a long time ago. Thank you that you are here

At 3:53, isn't it 1N to the left?

@sankalpmundra9651 2 года назад

exactly

@wxrlp Год назад

i just use circular motion to get the ketchup out lol

@OSC1990 28 дней назад

So you spin it around? Sounds....dangerous :)

Why did you make it 1000 meter and not keep it at 1km? U sed kg in the mass before

@OSC1990 2 года назад

The official units we use in the IB (SI units) use metres for length (and not km), but we use kg for mass (rather than g).

@ahilsarang2918 3 года назад

Hey, on EX: 3 isn't it 1N to the left??? 3:53

@OSC1990 3 года назад

Yes, it would be - you're correct, thank you! Cheers, Mitch

Hi. I have a problem. I tried to solve the problem for the 2nd law using the formula: a=m.s^-2 a=m.s^-2 s^2=m/a s^2=1000/0,533 s= 43,3 can you please help me to find my error? thank you

@OSC1990 3 года назад

The problem is that you used the wrong equation. We have many different formulations for acceleration (use the 4 equations of accelerated motion for example, or Newton's second law F = ma). However, what you used isn't an equation as such - you're just using the units (acceleration is measured in meters per second squared). You should use one of the other equations like I did. Newton's 2nd law actually has a better formulation using momentum, where we write that the resultant force = rate of change of momentum. In other words, Fnet = dP / dt
