Why is learning about pendulums worthwhile?

Using math, and the fact that the pendulum oscillates at a constant rate, Galileo was able to determine the approximate effects of the pull of gravity. These early experiments and the use of pendulums allow scientists to calculate the shape of the Earth.

Correspondingly, how does gravity affect a pendulum?

Gravity is one of two main forces acting upon a pendulum at any given time, helping create the back-and-forth motion of the swinging weight. What factors affect pendulum period? The mass and angle are the only factors that affect the period of a pendulum. b. The mass, the angle and the length are the three variables affecting the period.

Do pendulum clocks need batteries?

Little did I know back then, but pendulum clocks don't need batteries at all! It may seem like it's just idling around, serving no real purpose as it swings to and fro, but that action is actually what keeps the clock accurate to the second. Thereof, how does a pendulum keep swinging? The science behind the pendulum is explained through the forces of gravity and inertia. The Earth's gravity attracts the pendulum. This means that since the pendulum is now in motion, it keeps moving, unless there is a force that acts to make it stop. Gravity works on the pendulum while it is moving.

Thereof, does a pendulum ever stop?

A pendulum can only stop when its gravitational potential is lowest and it no longer has energy driving it. (This is of course assuming the pendulum is allowed to swing until brought to a stop by friction, rather than being stopped by an applied force.) And another question, how do pendulums synchronize? A study in the journal Scientific Reports has proposed a solution: the pendulums transfer energy to one another through sound pulses. A pair of Portuguese scientists hypothesised that these pulses might move from clock to clock, perturbing the swing of the pendulums and eventually causing them to synchronise.
