Due to the resistance of the air.
Air isn't a great big empty nothing, there's a certain solidity to it which is why we feel the air pushing against us on a windy day.
When you drop something or throw a paper plane it has to push the air out of the way before it can sink. Something which is very light, like a feather, will only push the air away slowly so it floats to the ground. Something heavy like a brick will fall quickly to the ground because it pushes the air out with more force.
In a nutshell it's due to air-resistance - the force of the air pushing against something.

Aerodynamics What makes a paper airplane fly? Air — the stuff that's all around you. carry your hand in front of your physique with your palm dealing with sideways so as that your thumb is on actual and your pinkie is dealing with the floor. Swing your hand returned and forth. Do you experience the air? Now turn your palm so that's parallel to the floor and swing it returned and forth returned, such as you're reducing it by using the air. you will experience the air, yet your hand is able to bypass by using it greater easily than while your hand grow to be grew to become up at a suited attitude. How fairly an airplane strikes by using the air, or its aerodynamics, is the 1st attention in making an airplane fly for a protracted distance. Drag & Gravity Planes that push a lot of air, like your hand did while it grow to be dealing with the ingredient, are reported to have a lot of "drag," or resistance, to shifting by using the air. in case you like your airplane to fly so some distance as obtainable, you opt for a airplane with as little drag as obtainable. A 2nd tension that planes would desire to triumph over is "gravity." you may desire to maintain your airplane's weight to a minimum to help combat against gravity's pull to the floor. Thrust & carry "Thrust" and "carry" are 2 different forces that help your airplane make a protracted flight. Thrust is the forward circulation of the airplane. The preliminary thrust comes from the muscular tissues of the "pilot" via fact the paper airplane is released. After this, paper airplanes are fairly gliders, changing altitude to forward action. carry comes while the air under the airplane wing is pushing up greater stable than the air above that's pushing down. that's this distinction in tension that enables the airplane to fly. tension could be decreased on a wing's floor by ability of making the air flow over it greater rapidly. The wings of a airplane are curved so as that the air strikes greater rapidly over the actual of the wing, ensuing in an upward thrust, or carry, on the wing. The 4 Forces in stability long flights come while those 4 forces — drag, gravity, thrust, and carry — are balanced. some planes (like darts) are meant to be thrown with a lot of tension. via fact darts have not got a lot of drag and carry, they be counted on greater thrust to triumph over gravity. long distance fliers are often outfitted with this same layout. Planes that are outfitted to spend a protracted time interior the air frequently have a lot of carry yet little thrust. those planes fly a sluggish and easy-weight flight.

the wing angle forces more pressure under the wing causing the plane to glide up til pressure above and under the wing stabalizes

snowdrop is sorta right. think aeordynamics(spelling?). The wind resists it and pushes it up. google it.
