Energy Forms and Transformations

As a roller coaster goes downhill

• kinetic energy is converted into potential energy.

  
  

• potential energy is converted into kinetic energy.

  
  

• electrical energy is converted into potential energy.

  
  

• potential energy is converted into electrical energy.

A boulder that is resting on the top of a cliff slips over the edge and accelerates towards the ground. As the rock falls, the amount of kinetic energy

• increases.

  
  

• decreases.

  
  

• stays the same.

  
  

• increases then decreases.
