A pulley in a catapult is used to provide mechanical advantage by increasing the force applied to launch the projectile. As the tension in the rope connected to the pulley increases, it allows for a greater potential energy to be stored and then released rapidly to launch the projectile further and with more force. The pulley system helps in making the catapult more efficient and powerful.
A catapult does not typically use a pulley. Catapults rely on stored energy, usually from a tension mechanism like a spring or twisted ropes, to launch projectiles. The release of this stored energy propels the projectile forward without the need for a pulley system.
Archimedes, an ancient Greek scientist, is credited with discovering the principle of the lever and inventing the double pulley and a type of catapult known as the “scorpion.” His contributions to mathematics and engineering greatly influenced scientific development during his time.
No, a clock gear is not a pulley. Clock gears are toothed wheels that interlock with each other to turn and move the clock hands, while a pulley is a simple machine that consists of a wheel with a groove around its circumference where a rope or belt can run to lift or move objects.
A motor pulley car science project typically involves attaching a small motor to a car chassis, with a pulley system to drive the wheels. By adjusting the size of the pulley, you can explore how different gear ratios affect the speed and torque of the car. This project demonstrates basic principles of mechanical advantage and gear systems in a hands-on way.
A catapult is probably more effective, though a pulley is easier and safer to use.

The "driving" or drive gear is the source of power or rotation. The driven gear is turned or moved by the drive gear. Example: The pulley on a motor is the drive pulley and a pulley on a pump is the driven pulley. Example: The pinion gear in a differential is the drive gear and the ring is the driven gear.

yes
Yes, for example you would want to move a gear so you would pull on one side of the pulley and it could get where you want it to get.
Most catapult's store their energy in twisted ropes, wound tightly by a wheel crank on the side of the catapult. The arm of the catapult is in between the two wound ropes. When a lever releases the gear attached to the rope, the rope unwinds, sending the arm of the catapult forward violently (flinging it's contents vast distances). Tribuchet's are a later more advanced manual artillery system. It used counter weight released by a pulley to fling massive boulders thousands of feet. But there is no real-world spring catapult. Most use ropes or counterweight and are far more capable.
