To find the amplitude of something that swings back and forth, you need to measure the maximum displacement from the equilibrium position. The number of complete swings, also known as oscillations or cycles, is not directly related to the amplitude.
To determine the amplitude, you would need to measure the maximum distance the object moves from its equilibrium position. The equilibrium position is the point at which the object is at rest, and the maximum displacement is the distance from this point to the farthest point the object reaches on either side during its oscillation.
If you have measured the maximum displacement (d) of the object, you can use that information to find the amplitude (A) using the formula:
Amplitude (A) = Maximum displacement (d) / 2
Note that the division by 2 is necessary because the amplitude represents half the total distance the object moves from one extreme to the other.
The number of swings or cycles per unit of time (such as 27 swings in 5 seconds) can provide information about the frequency or period of the oscillation, but it does not directly give you the amplitude.
