potential energy changes to kinetic energy
When the flood gates of a dam open, the potential energy of the water stored behind the dam is converted into kinetic energy as the water flows downstream. This change in potential energy to kinetic energy allows the water to generate electricity as it passes through turbines in the dam.
light bulb. Incandescent: Filament in an environment absent of oxygen, glows white hot when electricity passes through it producing light. Fluorescent: electrode "excites" mercury vapor which produces U.V. rays. U.V. rays hit a phosphorus coating on the inside surface of the bulb. The phosphorus coating adsorbs the U.V. ray and remits it as visible light. Light Emitting Diode or LED : Silicon crystal emits light when electricity passes through the diode in a certain direction. Organic Light Emitting Diode or OLED: Instead of a silicon crystal an organic-compound in used. Note: fire could be considered an answer.
it stays there. the electricity travels back and forth through the filament until you turn the lighbulb off.
As a cold front approaches, cloud coverage typically increases, often resulting in the development of cumulonimbus clouds and potential precipitation. Once the cold front passes, the cloud coverage may decrease as the cooler air displaces the warmer, moist air that was creating the clouds.
It moves at a slower speed!
nothing happens
A motor. If electricity passes through it, the motor rotates(kinetic/potential energy)

it absorbs it and passes it on.
The highest point of the pendulums swing is when the potential energy is at its highest and the kinetic energy is at its lowest. Kinetic energy is at its highest when at the lowest point of its swing, or equilibrium position, this is when the potential energy is at zero.

A pendulum has mechanical energy, which is made up of potential energy due to its height above the equilibrium position and kinetic energy due to its motion as it swings back and forth. This energy is constantly changing between potential and kinetic as the pendulum moves.
Think about what happens in a hydroelectric plant. The potential energy in the water is called 'potential' because the water has a place to go-- down. As the water falls it gains more and more kinetic energy. What is the water made to do before it's released? It passes through huge turbines and it makes the turbines spin. It's the spinning of the turbines that generates electricity. The kinetic energy of the water is converted to electricity.
Sources of energy, such as sunlight, reach the troposphere through radiation. Energy from the sun passes through the Earth's atmosphere and is absorbed by the surface, which then heats up and warms the air in the lowest layer of the atmosphere, the troposphere.
When electrical energy passes through a household device like a blender or a toaster, it is converted into other forms of energy. In the case of a toaster, electrical energy is converted to heat to toast bread. In a blender, electrical energy is converted to mechanical energy to blend food.
Pendulums move in a manner consistent with a harmonic oscillator. When you raise a pendulum, you are giving it potential energy (due to gravity). When you release it, the potential energy decreases counter to increasing kinetic energy as it is accelerated due to gravity. As it passes the lowest position, it begins its upswing, and the kinetic energy (momentum) carries it back up, increasing potential energy and decreasing kinetic energy (as it slows due to gravity pulling down on it). And the entire process repeats on the downswing after it reaches the maximum height of upswing. This process continues until frictional forces, air resistance, and other sources of kinetic inefficiency gradually reduce the overall energy available to the system, and then the pendulum approaches equilibrium at zero kinetic energy with respect to that reference frame.
