Trebuchets originated in China during the 4th century BC. They were later introduced to Europe during the Middle Ages and became a popular siege weapon for casting large stones at fortifications.
To launch a trebuchet, you first load the projectile onto the throwing arm and then release the sling. This unleashes the stored energy from the counterweight, propelling the projectile forward. The counterweight falling causes the throwing arm to swing up, launching the projectile.
Gravity affects the launch of spacecraft from Earth by pulling the spacecraft back towards Earth. The spacecraft must overcome this gravitational force through its propulsion system to successfully launch and enter into orbit. A balance between the force of gravity and the propulsion system is required for a successful launch.
After a rocket launch, the launch pad is typically unharmed (assuming a successful launch). The pad undergoes post-launch inspections and any necessary maintenance or repairs before it can be used for the next launch.
launchedThe past tense of launch is launched.
Trebuchets were medieval siege artillery used to throw heavy stones at castle walls and open a breach through which besieging forces could enter. They could also be used to launch projectiles (or a rotting dead cow in a primitive form of germ warfare) over castle walls to weaken and lower the morale of the besieged.
