Air resistance.
Inertia affects the movement of a pendulum by resisting changes in its speed or direction. When a pendulum is in motion, its inertia causes it to continue swinging back and forth until an external force, such as friction or air resistance, slows it down or changes its direction.
The force that causes the periodic motion of a pendulum is gravity. When the pendulum is displaced from its resting position, gravity acts as a restoring force that pulls it back towards equilibrium, resulting in the swinging motion.
Is law catalyst for starting the pendulum swinging? or is ethics? politics?
Obviously, it will stop after sometime , after swinging. It is because we cannot apply energy continuously to the swinging pendulum.
A pendulum slows down and stops swinging due to air resistance and friction at the pivot point, which gradually sap its kinetic energy. This energy loss leads to a decrease in the pendulum's amplitude and eventually causes it to come to a halt.
The path of a pendulum will follow a predictable pattern over the course of a day, swinging back and forth in a regular motion due to gravity and inertia. As long as there are no external forces acting on it, the pendulum will continue swinging along the same path. The gravitational force keeps the pendulum in motion, and the pendulum's potential and kinetic energy will continually cycle as it swings.
A swinging pendulum demonstrates primarily two types of energy - kinetic energy when the pendulum is in motion, and potential energy - based on how high it is above the mid-point of the swing. If not for friction, a pendulum would continue to swing forever, with the sum of the kinetic and potential energy remaining constant but the distribution between the two constantly changing as the pendulum moved through its swings.
A swinging pendulum will eventually stop because of friction with the air.
The apparent change in direction of a swinging Foucault pendulum is due to the rotation of the Earth. As the pendulum swings, the Earth rotates underneath it, causing the deviation in its path over time. This effect is known as the Coriolis force.
