Due to friction
it comes from friction
no
When a firefighter slides down a pole the thermal energy comes from the friction between the two objects.
The potential energy (due to the fighter's position in the Earth's gravity field). This is converted into kinetic energy as the fighter begins the slide and this kinetic energy is turned into heat energy by friction as the fighter slides.
Any time something falls, rolls, or slides down, gravitational potential energy is converted into kinetic energy.
Gravitational potential energy is converted into kinetic energy.
While a sled slides down a hill, it has kinetic energy(Ek = 1/2mv2).At the top of the slope, while not moving, it would have possessed gravitational potential energy. As it moves down the slope, however, some energy is converted to heat and sound in accordance with the Law of the Conservation of Energy which states that matter cannot be created or destroyed but is converted from one form to another.
Earthquakes
it has transform boundary
kenetic
kinetic
Mechanical Energy (:
usually there would earthquakes, volcanic eruptions, and mud slides
