For flight to be achieved then you must create a force of lift greater than the weight of the glider. this is achieved by the use of an aerofoil. ie the wings of the plane.
as an aerofoil travels through the air the leading edge cuts the airflow. air flowing over the top of the wings travels faster than the air under the wing Faster air = Lower pressure.
As there is lower pressure above the wing the force of lift is created. However to create this airflow the glider must be traveling forward at a sufficient speed to create sufficient lift.
Being a form of non powered flight it cannot do this alone. that is why it is towed to to the required altitude. Unhitched, And allowed to fall at a controlled speed (glide) downward .
to control the speed at which the glider falls, the pilot uses the pitch of the plane. nose up slows descent, nose down increases rate of descent, but also allows you to pick up forward velocity which can be used to re ascend.

What is the difference between a glider and powered aircraft?
a glider is sorta like a parachute and uses thewind to stay up but go's farther and a powered air plane can go up and down because it has its own power
How can a 500Kg glider stay in the air?
A glider can stay in the air by generating lift from the air flowing over its wings. This lift counters the force of gravity pulling the glider down, allowing it to stay airborne. By using updrafts, thermals, or ridge lift, a glider can sustain flight without the need for an engine.
What does glider work?
By glider do you mean like paper airplane?? it is held up by air pressure,,This will not work on the moon. There is no air there.
How does a hand glider stay in the air?
I think that a hang glider achieves flight by soaring through the air by getting a running start and the wings also help it to fly.Kiana xoxoxox
What do dugongs weigh?
Up to 500kg
What is the meaning of upto 500kg?
"Up to 500kg" means a maximum weight of 500 kilograms, not exceeding that limit.
How can a 500 kg gilder stay up in the air?
A glider can stay in the air by utilizing updrafts, thermals, and wind currents to generate lift. By skillfully maneuvering in these air currents, a pilot can maintain altitude and even gain altitude through techniques like soaring and ridge lift. Additionally, the design of the glider's wings and body shape allow it to efficiently convert air pressure differences into lift, keeping the aircraft aloft.
How does a cliff face warmed by the sun help glider pilots?
Cliffs warmed by the sun are good for glider pilots because it keeps them up. This happens with a process called thermal radiation. This is when the heat from the sun energy radiates. Thermal Radiation can also be heat from the sun bouncing off something, because the heat that bounces off that thing is thermally radiating through the air. This process can also happen with glider piloting. When the heat from the sun bounces on a cliff, it warms the cliff. This heat then bounces off it and creates a draft. The draft radiates in the air until it reaches the glider pilot and it then keeps the glider pilot up. This is why glider pilots have to be near a cliff or mountain to stay in the air. If they didn't do this or this process wasn't done. Eventually the glider pilot will fall and will be severely injured. So this process is really important for all things not just glider pilots.
How can gliders fly without engine?
Gliders don't have an engine. They need help to get up in the air but then it's up to the wing design and the air flow to keep them flying. One way that gliders get up into the air is called an aero-tow. A rope connected to a glider is attached to a regular plane. The glider pilot releases the rope when the glider is at the right altitude. Then the glider changes direction away from the airplane and flies on its own. Another way to launch a glider is called winch launching. The glider is attached by a long cable to a winch. A winch is a machine that's used for lifting things. The winch is activated and pulls the glider until it takes off. Then the pilot releases the cable and flies off without any further help. Once the glider takes off, the wings are the most important part. They keep the glider up in the air by creating "lift" so that the weight of the glider won't drag it down.
How does heat transfer in a glider?
Heat transfer in a glider occurs mainly through conduction and convection. The glider's skin absorbs heat from the sun and transfers it through conduction to the interior, making it warmer. Additionally, heat is transferred through convection as air inside the glider gets warmed up, rises, and is replaced by cooler air from outside, creating a cycle of heat transfer.
How does a balsa wood glider gain lift?
A balsa wood glider gains lift primarily through its wings, which are designed with an airfoil shape. As the glider moves through the air, the wings create a difference in air pressure; the air moves faster over the curved upper surface than the flatter lower surface, resulting in lower pressure above the wing and higher pressure below. This pressure difference generates lift, allowing the glider to rise and stay aloft. Additionally, the angle of attack, or the tilt of the wings relative to the airflow, can enhance lift up to a certain point before causing drag or stalling.
Do gliders have engines?
Yes and no... Pretty much every glider does not have an engine. A tow plane is used to take the glider up, then it detaches and uses thermals which come from the ground to lift its self up. Just like what a bird does. When a bird flies in circles, it has found a thermal and you will notice it is rising up... On the other hand, Germany has invented a glider with an engine that comes out for take off, and as soon as the glider is in the air, the engine goes back in.
