Gravitation energy. Water at a high elevation drops down to a lower elevation and releases gobs of energy. It could also be thought of as a drop in potential energy. Interesting to note there is a huge hydro-electric plant that utilizes this exact energy source.
Yes, Niagara Falls is a classic example of kinetic energy being converted into potential energy. As the water flows down the falls, it gains speed and kinetic energy, which is then converted into potential energy as the water rises higher above ground level.
Kinetic energy is the energy in a mass of matter that is in motion, the energy of motion. Potential energy (where mass is in a gravity field) can be converted into kinetic energy Chemical energy (of an explosion) can be converted into kinetic energy Electrical energy can be converted into kinetic energy (eg in an electric motor)
Potential energy can be converted into kinetic energy. For example, when an object is released from a height, its potential energy due to gravity is converted into kinetic energy as it falls. This conversion follows the law of conservation of energy, which states that energy cannot be created or destroyed, only converted from one form to another.
Yes, kinetic energy can be transformed into potential energy, and vice versa. For example, when a roller coaster reaches the top of a hill, its kinetic energy (motion) is converted into potential energy (height). Conversely, when the roller coaster descends the hill, the potential energy is converted back into kinetic energy.
When potential energy is converted into kinetic energy, it is transformed into the energy of motion.
Since energy is ALWAYS conserved, anything that happens is an "example". For example, an object just sitting around. However, it is usually more interesting to analyze what happens when one type of energy is converted to another. For example, if a car brakes, the car's kinetic energy is converted to heat (in the brakes); when you throw an object up, kinetic energy is converted to potential energy; when it falls back down, the potential energy is converted back to kinetic energy; and if in this example there is air resistance, part of the kinetic energywill be converted to heat.
It CAN be converted to kinetic energy, but it won't always do so.
Gravitational potential energy being converted to kinetic energy
A radio is an example of electrical potential energy because it relies on stored electrical energy to function. When the radio is turned on, this potential energy is converted into kinetic energy in the form of sound waves.
Potential energy can be converted into kinetic energy, as seen in a swinging pendulum where potential energy at the highest point is converted into kinetic energy at the lowest point.
If potential energy is not converted into kinetic energy (or into any other type of energy) then it remains potential. Potential energy does not expire.
Releasing a compressed spring is an example of kinetic energy being converted to potential energy. When the spring is released, the potential energy stored in the compressed spring is transformed into kinetic energy as the spring expands and moves.
