The speed of the system when it passes through the equilibrium position is
, and this corresponds to the maximum speed of the oscillator.
The angular frequency of the oscillator is given by
where k is the spring constant, and m the mass. Substituting the data, we find
and since the amplitude of the oscillation, A, is related to the maximum speed by
we can re-arrange this equation to calculate A:
This is true
In the winter they just fall off
∆y is change in y (velocity) and ∆x is change in x (time)
So from the graph we see that ∆y is zero and ∆x is also zero (value is changing with same ratio)
∆y/∆x= slope = 0
A. Because its now a smaller container with the same amount of gas
