- - - - Gravitational potential
      - Kinetic
      - Thermal
      - Elastic
    - - Electrically
      - By radiation
      - Mechanically
- - - - If ride initially at rest and velocity at bottom= v
      - Kinetic energy= 1/2mv^2
      - Loss of potential energy=mgh
      - Work done to overcome friction and air resistance= mgh-1/2mv^2
- - - - If moves at constant velocity and height resistive forces are equal and opposite
      - When it gains speed output force is greater that resistive forces
