Study the scenario.
An isolated system includes a girl, a slide, and the Earth. The girl is initially at the top of a slide, storing 100 J of gravitational energy.
As the girl slides down the frictionless slide, what happens to the total energy of the system?
Responses
The total energy of the isolated system increases to more than 100 J of energy as energy is released as the girl slides down the slide.
The total energy of the isolated system increases to more than 100 J of energy as energy is released as the girl slides down the slide.
The total energy of the isolated system decreases to 0 once the girl reaches the bottom of the slide.
The total energy of the isolated system decreases to 0 once the girl reaches the bottom of the slide.
The isolated system stores slightly less than 100 J of total energy as some of it is converted to heat as the girl slides.
The isolated system stores slightly less than 100 J of total energy as some of it is converted to heat as the girl slides.
The isolated system stores 100 J of total energy, but it is converted to a different form of energy.
The isolated system stores slightly less than 100 J of total energy as some of it is converted to heat as the girl slides.
The correct response is: The isolated system stores slightly less than 100 J of total energy as some of it is converted to heat as the girl slides.
As the girl slides down the slide, some of her gravitational energy is converted into kinetic energy, which allows her to move down the slide. However, due to friction between the girl and the slide, some of this energy is also converted into heat. Therefore, the total energy of the system decreases slightly from the initial 100 J of gravitational energy.
