The Equations of Rotational Kinematics help

AI Thread Summary
In the discussion about rotational kinematics, a fan's rotation of 2 complete revolutions is compared to linear kinematics. The key focus is on identifying the analogous quantity, with participants debating whether it relates to position, displacement, velocity, speed, or time. The consensus leans towards displacement, as time is not mentioned in the context of the question. The reasoning highlights that since velocity and speed depend on time, they are not applicable here. Ultimately, the discussion concludes that the correct analogy is displacement.

Consider a fan that has rotated by a total of 2 complete revolutions from where it started. This quantity (2 revolutions) is analogous to what quantity in linear kinematics?

Position

Displacement

Velocity

Speed

Time





Time


Homework Equations



I am leaning towards velocity since displacement over time is velocity...

The Attempt at a Solution

Is time mentioned at all in the question, aside from the possible answers?
 
no, it is not.
 
Then it's probably not anything to do with time, like velocity or speed.
 
so displacement
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
