Why the pendulum loses energy and eventually comes to a stop?

As the bob reaches point P, its potential energy becomes zero and the bob possesses only kinetic energy. The bob does not oscillate forever. It comes to rest because air resistance resists its motion. The pendulum loses its kinetic energy to overcome this friction and stops after some time.

When a pendulum is swinging it slows down because energy is lost?

With each swing of the pendulum there is a little bit of energy lost due to friction in the rope. This loss of energy will dampen each swing, causing the maximum height of swing to go down each time.

How does a pendulum store energy?

The swinging of a pendulum is powered by an ongoing process of storage and transformation of energy. When the weighted end of the pendulum is raised to one side by an outside force, the system is given energy. At this point the energy is stored in a form called potential energy.

Why does the pendulum make a good clock?

The advantage of a pendulum for timekeeping is that it is a harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. Pendulum clocks are now kept mostly for their decorative and antique value. Pendulum clocks must be stationary to operate.

Where does the energy go when a pendulum stops swinging?

At that point the kinetic energy starts transforming back into potential energy on the other end of the swing. Then, the pendulum actually comes to a stop! It comes to a stop for a very short time at the end of each swing. When it is “at rest” the energy is once again potential energy.

When a pendulum swings when is the potential energy greatest?

If kinetic energy is highest at the bottom of the pendulum, then that is where potential energy is the lowest. So potential energy would be highest when the pendulum is at its highest point on either side of its motion where it is stationary for an instant.

How does pendulum clock works?

As it swings from side to side, it rocks a lever called an escapement that locks and then unlocks the part of the mechanism driven by the falling weight. Since (in theory, at least) a pendulum of a certain length always takes the same amount of time to swing back and forth, the pendulum is what keeps the clock to time.

How did the pendulum clock affect society?

The introduction of the pendulum increased the accuracy of clocks enormously from about 15 minutes per day to 15 seconds per day leading to their rapid spread replacing older designs.

What transformation of energy happens in the swinging pendulum?

As a pendulum swings, its potential energy converts to kinetic and back to potential. Recall the concept of conservation of energy—that energy may change its form, but have no net change to the amount of energy.
