you have to add or take away energy
Resistance force is the force which an effort force must overcome in order to do work.
surface tension
that is true
Push it, or pull it. You may have to push hard enough to overcome a force of friction.
In order to change direction, the applied force (represented as a Vector) must change DIRECTION. A change in magnitude of the Force is not necessary.

surface tension

Molecules in a liquid must overcome intermolecular forces before they can evaporate. The molecules must also be moving in the right direction and located near the surface in order for evaporation to occur.
it can either be converted into solid ice or liquid water and for both the reactions you have to release the heat energy of gas moloecules in order to overcome their kinetic energy and intermolecular spaces..

Frictional force resists movement. In order to set an object into motion (or accelerate an already moving object), the force of friction must be overcome.
To need force
Thrust is the produced force of the aircraft that propels the aircraft forward in order to overcome drag. Drag is the natural force of the air that resists the motion of the aircraft.
