Eli5: How can a plane try and do a touch and go landing?

Question

You know when planes try to land and a problem arises, how have they got enough lift to immediately take off again? Isn’t that the purpose of the run up to taking off (normally)?

Answer 1

The pilot ‘puts the pedal to the metal’, increasing the engines’ thrust, the plane’s speed, and thus the wings’ lift. On approach to landing, the plane had nearly enough lift to maintain altitude, so increasing lift a bit gets it going back up instead of down.
