The resistance force
Gravity is the main resistance force on any aircraft. Wind resistance would be second.
Inertia
It is friction. In air, it can also be called air resistance. Similarly, in water, it can also be called water resistance.
resistance (friction)
resistance force.
Air resistance.
resistance force
Possibly water resistance (drag)
The answer is gravity.they also experience a upward force called air resistance
Resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pound-force. Resistance force is used to calculate the work output using the equation: Work output = Resistance force * resistance distance
Resistance force is the force which an effort force must overcome in order to do work.
