An engine or some other means of propulsion.
A glider is an aircraft that does not have an engine and relies on natural forces like wind and gravity for flight. It typically launches from a high point and glides through the air. An airplane, on the other hand, is powered by engines that generate thrust to propel it through the air.
The Wright brothers invented their glider to fulfill their ambition of achieving powered flight. They used the glider to test their ideas on aerodynamics and control systems that would later be incorporated into their first powered airplane.
the wright brother invented the glider in the 1890s it was a successful one similar to a airplane but without the engine
The independent variable of a glider, if it is an air glider, would be the thermal updrafts available at any flight. Without effective thermals, it makes it difficult for a glider to maintain lift and develop elevation for sustained glides.
When the Wright brothers had trouble controlling their glider, they made adjustments to the wing-warping technique to improve stability and control. They also studied bird flight to gain insights into aerodynamics, which ultimately helped them achieve controlled powered flight with their first airplane in 1903.
An airplane with no motor is called a glider.

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.
The Wright brothers first airplane was a glider, -wind powered.
an airplane with no engine, it's carried up by a tow plane, released and glides back to earth
In 1901 in their glider.
It was based on the success of their 1902 glider.
