Metric Mastery B

[Skink]

It's within the scope of the rules. I could give you a 2lb. weight labeled as such and ask what its mass is in kg. The 2lb. part just helps you out, far as I can tell, in case you know the conversion approximately. Is that how it's going to be at Nationals? Doubtful. Then again, I'm unsure what the focus of this event will be since there really are four types of questions, at least. Read back if you want to see more on that.

I would doubt that they would give you an English measurement and ask you to convert it to metric. That just seems to be too obvious and easy.

Well, among common metals you have things like iron and aluminum, which have respective densities of 7.87 g/ml and 2.7 g/ml, so I think so far randomly guessing is our best strategy for this.

I agree...the only metals they really give you at competition are Fe, Al, and Cu. Three out of four competitions I have been in have dealt with copper's density.

On the contrary, I have seen those types of questions at competition before.

I was just wondering if anyone knows what a station might be like for measuring speed?

It might be how fast is this Hot Wheels car traveling as it is going down this twisty turvy Hot Wheels ramp.

tigerpanda, you could have definitely put all of those posts into one. Just a tip; double/triple posting is often looked down upon on forums like these.

Usually they use a pendulum, in my experience.

Are speed and time referring to the same thing here?

Not really, speed is judging how fast something is moving(kilometers per hour), and time is how long something would take.

Right; the units would be different. Kilometers per hour/meters per second for speed and seconds for time.

What about force questions?
