Amplitude is the height from the mean, or rest, value of the function to its maximum or minimum. The period is the distance required for the function to complete one full cycle. For the sine function, the amplitude is given by and the period is defined as. The same is true for a cosine function.
The acceleration of an object carrying out simple harmonic motion is given by. The positive quantity [omega]2 xm is the acceleration amplitude am. Using the expression for x(t), the expression for a(t) can be rewritten as. This shows that the acceleration is proportional to the displacement, but opposite in sign.
