when you add more weight to a pendulum the number of swings increases. But what causes this?
please be seriuos about this

centripetal force. If mass is added on to a branch of a tree, the branch will bow down. With the pendulum, it is the same way. The force of gravity pulls down harder. But since the swings move in half circles, the gravity goes sideways, east and then west. This is called centripetal force, object moves in circular motion.

momentum. the number of swings a pendulum performs before it comes to rest is equal to the (potential energy + kinetic energy) / (energy loss to friction (air and axel)). The energy loss on each swing is effectively constant. The potential+kinetic energy is twice as great if you increase the mass by 2.
