In some newer coaster designs, a catapult launch sets the train in motion. There are several sorts of catapult launches, but they all basically do the same thing. Instead of dragging the train up a hill to build up potential energy, these systems start the train off by building up a good amount of kinetic energy in a short amount of time.
potential energy
Potential energy is when the particles are at rest and kinetic energy is when the particles are in motion.
It is not sure yet. But NASA has predicted the date to be as between 2014 and 2015.
the standard cell potential is the cell potential at standard conditions (25C , 1 atm , and 1M ) but the cell potential is the cell potential of the cell under a real condition and we use nernst equation . i hope this is useful
Potential energy is directly proportional to height.

a trebuchet is a type of catapult. it used a counter weight
The difference is that the trebuchet sling the stone or fireballs .A catapult doesn't sling and it doesn't carry as much weight
I always thought that an onager was a particularly large type of catapult
Between 50 and 85 MPH depending on power you give
Glass coasters are a houseware accessory used to protect a surface from a cup, glass, or something other type of container that might sweat and leave a water ring on a table. A roller coaster is an amusement park thrill ride that might make you barf.
it is
The difference in potential energy between the reactants and products.
There is no potential difference between identical charges
electric potential is potential difference between two points in closed circuit. but electromotive force is potential difference in any open circuit.
The potential difference between the ends of a conductor is called voltage.
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.
