Gravity and wind resistance.
In plane forces, all forces are confined to a two-dimensional plane, while in space forces, forces can act in three dimensions. Plane forces involve only forces in the x and y axes, while space forces can include forces in the z axis as well. Space forces require vector analysis in three dimensions, while plane forces use scalar analysis in two dimensions.
Forces that cancel each other out are coplanar, all reside in the same plane.
When a plane is sitting still on the tarmac, the main forces acting on it are gravitational force pulling it towards the center of the Earth and normal force acting perpendicular to the surface of the tarmac to support the weight of the plane. Additionally, there may be small frictional forces between the wheels of the plane and the tarmac keeping it from moving.
The four forces that act on a plane in flight are lift, weight (gravity), thrust, and drag. Lift is generated by the wings to overcome gravity (weight), while thrust from the engines propels the plane forward to overcome drag, which is the resistance of the air against the forward motion of the aircraft.
When a plane is ascending, the force of lift generated by the wings must overcome the force of gravity pulling the plane downward. The engine also provides thrust to power the plane upward. Additionally, air resistance (drag) influences the speed and efficiency of the ascent.

Coplanar forces systems have all the forces acting in one plane. It also means that all forces act within a single plane instead of three dimensions.
When all the forces of a force system act in one plane it is called coplanar force system. If the forces act in more than one plane then it is forces in space. In this case forces are not contained in one plane. When all the forces of a system pass through a common point they are called concurrent forces. Thus we have concurrent coplanar forces when all forces are in one plane and pass through a common point. Also when forces in space pass through a common point we have concurrent forces in space.
Coplanar forces are a set of forces all of which act in the same plane. Non-coplanar forces are a set of forces in which at least one act in a direction incline to the plane formed by two of the forces.
The four forces of flight during flight are lift gravity thrust and drag
Lift: The force that keeps the plane flying.Drag: The force that slows down the plane. Weight: Theattractionto the ground.
These are forces which act in the same plane (coplanar, not coplanner!) and that their lines of action all meet at a single point.
Coplanar just means that all forces act within a single plane, rather than in three dimensions. Examples aren't really necessary -- it's really a mathematical abstraction, because in the real world forces act in three dimensions.

i jump off the plane before it crash
not if you dont want to
No, the plane would weigh the same.
