Answer;
The energy turns into heat, or thermal energy.
Step-by-step explanation;
- According to the law of conservation of energy; energy can not be created or destroyed, but can be transformed from one form to another.
- Therefore; a decrease in kinetic energy and potential energy when a jumbo jet slows and descends on the approach to landing, indicates a transformation energy to another form, which is heat energy or thermal energy but not destruction of energy.
