What is the effect of the second pendulum swings onto the first pendulum?

As soon as the second pendulum starts to swing, it starts pulling back on the first pendulum. These pulls are timed so that the first pendulum slows down. To picture this, it may help you to think of a playground swing.

Moreover, what happens if you just let the pendulum swing for awhile?

But what happens if we pull the pendulum bob up to one side and then release it? It will swing from side to side for a long time. At the height of each swing, in the instant when the bob is motionless between upswing and downswing, the system has all potential energy and no kinetic energy. Would a pendulum swing in space? No, it wouldn't swing back and forth. Pendulums on Earth require gravity to pull the swing back down after they swing upwards. Since there is no gravity in orbit, there is no force that pulls the pendulum down and make it swing back and forth.

Will things move forever in space?

Objects in Motion Now consider an object in motion. straight line indefinitely. of outer space, and the object will move forever due to inertia. Do pendulums slow down? A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. 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.

Consequently, are pendulums infinite?

pendulum is infinite.. Actually the pendulum's time period is : T=2??l/g applicable when the angle made by the string from the mean position is small.. that is we consider it to be SHM. Does a double pendulum ever stop? (i.e. ones which dissipate the energy of the system, examples would be air drag and friction in common cases). Also, any pendulum which is left initially at its lowest energy state (the bob at the bottom most part of its trajectory), it would stay that way forever. (Assuming no external forces.)
