A child sits at the top of a slide at a playground. He wiggles forward slightly, and then slide all the way down with no further effort. Explain the source of the force acting on the child, and how you would calculate the work being done.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

the components of a vector are the parts of the vectors that are to each other.
