The Harrier jet does this
No. Jet engines, by nature of their design, do not have a reverse function. To slow down, the pilot opens the flaps, reduces engine power, and deploys the airbrake.
The wheels along with the system is called Landing Gear. The Landing Gear can be retracted soon after take-off. Stationary landing gears slow the aircraft down.
A jet plane has "thrust reversers" which effectively fold the jet engine's thrust around to the front, and these are used at landing to slow the plane down quickly. They are not used, as far as I know, to push the plane backwards from a standing stop; I suspect they are not efficient enough to do that. Jet planes are usually "pushed back" from the gate by specially designed trucks. Propeller planes similarly have a mechanism for turning the propeller blades backward, to slow them down on landing; so I believe they can generally roll themselves backwards on the ground if required. Neither type of plane can fly backwards; the aerodynamics would be all wrong.
Slow down the Acceleration of free fall.
They use Arrestor Cables to catch the landing gear and slow the plane down.
Flaps and stats increase lift for takeoff and slow you down, for landing.
More lift is required during landing to counteract the effects of gravity and slow down the aircraft for a safe touch down. By increasing lift, the plane can descend at a controlled rate and reduce its speed gradually without descending too quickly, ensuring a smooth and safe landing.
A rocket ship lands by firing its engines in reverse to slow down its descent, then using thrusters or landing legs to touch down gently on the landing surface. The landing is usually controlled remotely by pilots or automated systems to ensure a safe and precise touchdown.
You start to slow down & get close to the ground then your landing gear comes out then you can land
When you deploy your parachute, you do not go up; you simply slow down due to air resistance and drag. The parachute increases your air resistance by capturing air in its canopy, which slows your descent speed until you reach a safe landing speed.
Because landing at 25,000 km/h is impossible.
