    Pendulum Swing
AI Thread Summary
The discussion focuses on the behavior of a pendulum swinging through different arcs, specifically comparing a one-degree swing to a two-degree swing. It highlights that the time period of a pendulum's swing is determined solely by its length and the acceleration due to gravity, not the amplitude of the swing. The formula T = 2π(L/g)^(1/2) confirms that the period remains constant regardless of the swing's amplitude. Participants affirm that real-life observations, such as those from using a swing, align with this mathematical model. Overall, the conclusion is that the time required for the two-degree arc is the same as for the one-degree arc.

A pendulum swings through a maximum arc of one degree in 1 sec. Later, the pendulum is made to swing through a max of 2 degrees. What is the time required for the 2 degree arc?

T = 2pi(L/g)^(1/2)

Is the time the same since the swing depends on only the length and gravity due to acceleration?

Hi there,

Have you never used a swing a kid, and noticed that the period is the same whether you rock just a bit or whether you make the whole structure jump around. This is a real life problem. Now if you want to have a mathematical model that explain that, you gave the equation, in which the amplitude of the movement is not involved in the period.

And it works. Mathematical modeling can explain a real life problem. YEAH!

I did not sutdy all these years for nothing.

Just kidding about the last part.

Cheers

Yes.
 
Thanks for the confirmation :smile:
 
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}...
