IV characteristics of an ohmic device
This curve appears to be the integral of a sinusoid. It could
therefore represent the total electrical power dissipated as a
function of time for a device through which we pass an alternating
This curve could represent the amplitude of oscillation of an
undammed spring which is the suddenly stopped.
This curve could represent the magnitude of a pendulums
displacement from its equilibrium position (assuming the pendulum
begins at maximum displacement).
Charging of a capacitor
Radioactive decay. This curve could represent the number of nuclei
decaying per second from some radioactive source.
Normal distribution: Height or weight
This could also be a resonance curve. The Y axis could be the
amplitude of osciallation and the X axis could represent the
frequency of the input, at the natural frequency we would get a
very high amplitude response.
This curve could represent the fracture toughness of an alloyed
metal, the Y axis representing the fracture toughness and the x -
axis representing the volume fraction of the alloy.
