With modifications, a ballista can shoot bolts (thick, heavy arrows), darts (skinnier and lighter than bolts) and round things (like rocks, boulders). And we divide that by Pi times 9.00 centimeters written as meters so centi is prefix meaning ten times minus two and we square that diameter.

A catapult uses the sudden release of stored potential energy to propel its payload. Calibration will take into account all accelerations (including air resistance). Experimenting with a catapult and launching objects at a target can be fun for families or classes, and a catapult activity invites discussion of both the physics and math at work in the way a catapult operates and in how accurate one's aim may be. A catapult uses the sudden release of stored potential energy to propel its payload. Having said all this, there are situations where it makes sense to look at rotating objects from When the arm is pulled back, the tension in the cord will pull the arm forward.

The ancient Greeks probably tried to get as much use out of one object as possible--but, in more modern times, they likely had different things for different purposes. (2009/2018) Centrifuges. becomes when it spins wet laundry at high speed to remove the water. All catapults rely on energy. Soldiers would use the catapults in both siege and defense maneuvers to capture or protect cities or castles. But balancing test tubes exactly can be very difficult, so machines like this one have flexible rubber collars on their spindles that allow the loaded pockets to rotate about their true center of gravity, thus minimizing any unwanted vibration.
