A helicopter takes off from the ground and rises vertically. It then hovers at a constant height
above the ground.
Which sequence of energy changes takes place during the gain in height?

A
$Chemical \rightarrow kinetic \rightarrow gravitational\ potential$
💡 Explanation:
First the fuel in the engine gives chemical energy during burning. That chemical energy then converts to kinetic energy if the rotor of blades of the helicopter. Then kinetic energy converts in gravitational potential energy as it gains height.
