A swinging pendulum has potential energy at each end of it's travel (when it stops momentarily) This energy is converted to kinetic energy as it swings down and back to potential energy as it swings up the other way.
If at the top of the swing the pendulum is STOPPED then it has zero kinetic energy.
-- If you're talking about a pendulum, then the potential energy is highest and kinetic energy is zero at the ends of the swing, and potential energy is lowest and kinetic energy is highest in the middle of the swing. -- If you're not talking about a pendulum, then the preceding may be completely wrong.
When a pendulum is released to fall, it changes from Potential energy to Kinetic Energy of a moving object. However, due to friction (ie: air resistance, and the pivot point) and gravity the pendulum's swing will slowly die down. A pendulum gets its kinetic energy from gravity on its fall its equilibrium position which is the lowest point to the ground it can fall, however, even in perfect conditions (a condition with no friction) it can never achieve a swing (amplitude) greater than or equal to its previous swing. Every swing that the pendulum makes, it gradually looses energy or else it would continue to swing for eternity without stopping. Extra: Using special metals that react little to temperature, finding a near mass-less rod to swing the bob (the weight) and placing the pendulum in a vacuum has yielded some very long lasting pendulums. While the pendulum will lose energy with every swing, under good conditions the amount of energy that the pendulum loses can be kept relatively small. Some of the best pendulum clocks can swing well over a million times.
a pendulum
if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
When the pendulum is at the top of its swing, the speed is zero so the KE is also zero.
No, at the top of a swing, the pendulum has potential energy due to its position above the ground, which is considered gravitational potential energy. There is no chemical energy involved in the motion of a pendulum at the top of its swing.
When a pendulum reaches the end of its swing, the energy within the pendulum is potential energy, which is due to its position being at its highest point. At the highest point of its swing, the kinetic energy is at its lowest as the pendulum comes to a brief pause before reversing direction.
The maximum potential energy in a pendulum is reached when the pendulum is at the highest point of its swing, also known as the peak of the swing. This is where the potential energy is at its maximum because the height is greatest and gravity has the most impact on the pendulum.
If at the top of the swing the pendulum is STOPPED then it has zero kinetic energy.
The energy of motion, also known as kinetic energy, causes objects to move or undergo changes in position. It is transferred between objects during collisions and is responsible for the movement of vehicles, the swing of a pendulum, and the flight of birds.
You can make a pendulum swing faster by increasing its initial height or by shortening the length of the pendulum. Both of these actions will result in a larger potential energy that will be converted into kinetic energy, causing the pendulum to swing faster.
In a pendulum clock, the potential energy stored in the raised weight or spring is converted into kinetic energy as the weight descends or spring unwinds. This kinetic energy is then transferred to the pendulum, causing it to swing back and forth. The energy is continuously converted between potential and kinetic as the pendulum oscillates, regulating the clock's movement.
Potential energy
At the lowest point of its swing, a simple pendulum's velocity is at its maximum, and its potential energy is at its minimum. The kinetic energy is at its highest since the pendulum has the highest speed.
The pendulum's potential energy is highest at the highest point of its swing and lowest at the lowest point. As the pendulum swings, potential energy is converted to kinetic energy and back again.
The angle of release of a pendulum affects the swing time because it determines the initial potential energy that is converted to kinetic energy during the swing. A larger angle of release results in more potential energy at the start, leading to a longer swing time as the pendulum must swing through a larger arc to reach its highest point. Conversely, a smaller angle of release corresponds to less initial potential energy and a shorter swing time.
