Moving forward, air rushing over the wings causes them to produce lift. When the amount of lift created is greater than the weight of the plane it will rise off the ground.

How long does it take an airplane to get off the ground?

Depends on the aircraft, and the velocity of the air over the wings that produces enough lift to get the aircraft into the air. For aircraft that are STOL capable (Short Take Off and Landing) this time will be short, but ultimately it depends on the wind conditions, and the thrust of the aircraft. VTOL (Vertical Take Off and Landing) aircraft can take off instantaneously. There are too many variables to give a short answer, as stated above, but as an example, a fully loaded modern day commercial airliner like the Boeing 767-400 might have a take-off run of 9000' to 9500' before the main landing gear actually lifted off the ground.


How fast does a passenger airplane take off?

A passenger airplane typically takes off at a speed of around 150 to 180 knots (170 to 210 mph) depending on the size and type of aircraft. The exact speed can vary depending on factors such as aircraft weight, runway length, and weather conditions.


What type of energy does an airplane taking off have?

An airplane taking off has kinetic energy, which is the energy an object possesses due to its motion. As the airplane accelerates down the runway and gains speed, it builds up kinetic energy that is then used to lift off the ground and continue its flight.


Is an airplane taking off down a straight runway an example of accelerated motion?

Yes, as the plane must accelerate from a stop to its takeoff airspeed.


What forces are applied on an air plane on the runway?

On the runway, the main forces acting on an airplane are thrust (propels the plane forward), drag (resists the plane's motion), lift (opposes gravity to keep the plane airborne), and weight (pulls the airplane downward). These forces work together to allow the airplane to take off and maintain controlled movement on the runway.
