kinetic energy and potential kinetic energy decrease because a) the air is resisting the swinging item, so the item needs more energy (that it doesn't have) to continue swinging at its starting speed; and b) gravity is pulling it towards the earth. gravity is stronger than the small amount of energy put into the swinging item.
Air resistance.
The pendulum will lose energy, due to friction.
A swinging pendulum will eventually stop because of friction with the air.
Rolling friction causes a car to stop.
condoms.
Air resistance.
Stop the ship.
Stop the ship.
Obviously, it will stop after sometime , after swinging. It is because we cannot apply energy continuously to the swinging pendulum.
Gravity and the tension in the string.
Yes, something can cause it to stop continuously swinging.
Air resistance.

A swinging pendulum will eventually stop because of friction with the air.
Just click anywhere again when.
A pendulum does not keep swinging because the kinetic energy that it has as it swings is detracted from somewhat by the air. This may be easier to see with a comparison to friction. Air resistance acts on a pendulum swinging through air just as friction acts on an object sliding across a surface, causing it to come to a halt.
