An engine producing THRUST keeps an airplane moving forward. Types of engines used by airplanes include reciprocating engines, turbo prop engines, turbojet, and turbofan engines. Some manufacturers are developing electric engines and one bicycle racer powered a very lightweight airplane using pedal power connected to a propeller.
Yes, and any pilot can tell you about flying into a wind but moving backwards with respect to the ground. But be certain you understand that the airplane keeps flying, it just doesn't move forward.
keeps the plane from moving sideways
The ball keeps moving forward because of its momentum, which is not a force.
Lift keeps an aircraft up, thrust pushes it forward.
The force you seek is gravity.
Air moving over the rotor disk, much like an airplane wing.
It keeps moving forward or moves with the cold air it depends
It keeps you from moving forward if the car is hit or stops suddenly.
No. The forward motion creates the lift that keeps it in the air. Even when all engines are shut down, momentum keeps a plane moving forward. As the momentum decreases, the plane begins to descend; forward motion eventually changes to downward motion. Even a passenger jet that explodes or has been hit by a missile keeps moving, that is the pieces keep moving. I will only stop moving when it, or the pieces hit the ground (or is purposely parked at an appropriate place).
The engine makes an airplane go forward.
The lift of the paper airplane is created by the wings and the thirst that you provide with your arm. Gravity is the force that brings the plane down and keeps it moving once the energy you provided with your arm has dissipated. The downward motion of the airplane caused by gravity keeps it moving forward which allows the wings to continue to provide lift.
Inertia keeps you moving forward.
