A body undergoes simple harmonic motion if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean.
Provided the amplitude is small, a swing is an example of simple harmonic motion.

Effect of large angle to oscillation?
The motion is likely not to be a simple harmonic motion as required for the formula for the period of a pendulum to work properly. The angle of swing is likely to reduce.
What are the 4 example of bodies performing simple harmonic motion?
Pendant in a clock Swing Suspended spring with mass attached An object moving back and forth between rubber buffers along an air track
Is a swing an an example of a simple machine?
Yes, the simple machine is a lever if you look at the top of a normal playground swing.
Why are positive and negative numbers used on a harmonic motion graph?
Since amplitude can vary, it is inconvenient to set "0" at the maximum swing point. This can move your zero and all successive measurements with just a touch. Additionally, "simple harmonic motion" is easily described by combinations of the sine and cosine functions, and they yield positive and negative values of equal magnitudes. So it is *easier* to set zero at "mid span".
