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
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

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.
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.
How does a hot air balloon stay up?
it stays up because there is a fire inside of it and the gases from the fire focuses the hot air ballon to stay up
How does convection work on a glider?
If the glider has a roasing chicken inside, it will cause some convection waves, this will lift the Glider up.
How can a glider plane increase its altitude?
first the are towed into the air via another plane then it is released then it ride a up draft (a rising hot or warm air mass) almost how hot air balloons work
Why don't rockets need air to stay up?
This is a bit of a silly question. Rockets create thrust which a force which keeps up. They are not dependant on air to stay u
