If a roller coaster has 50,000 J of potential energy at the top of the first hill, how much kinetic energy does it have at the lowest point?

50,000 J because of the transformation of energy

Explanation:

newton's first law of motion

  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
