Why does length of pendulum affect period?

How does the length of a pendulum's string affect its period? (Answer: A pendulum with a longer string has a longer period, meaning it takes a longer time to complete one back and forth cycle when compared with a pendulum with a shorter string.

Also, why do pendulums not stop?

If there were no friction or drag (air resistance), a pendulum would keep on moving forever. In reality, each swing sees friction and drag steal a bit more energy from the pendulum and it gradually comes to a halt. But even as it slows down, it keeps time. Subsequently, is pendulum a periodic motion? A simple pendulum consists of a relatively massive object hung by a string from a fixed support. It typically hangs vertically in its equilibrium position. The motion is regular and repeating, an example of periodic motion.

Accordingly, is a pendulum a wave?

A pendulum may be considered an example of Simple Harmonic Motion, but it can't be considered a wave due to its characteristics. At what place the motion of simple pendulum will be lowest? It is at the equator,which could be predicted to have the lowest value of g. Hence time period being inversely proportional to the sqrt of 'g' will be the highest.So at the equator the time period is the lowest for the simple pendulum.

Does a pendulum swing faster with more weight?

The location of the weight, not the amount of weight, affects how fast a pendulum swings. What's going on? When you add a weight to the bottom of the pendulum on the right, you make it heavier. But since weight doesn't change the effect of gravity on an object, the two pendulums still swing at the same rate.
