A crossbow gains it's potential energy From the wood on the front which bends when the string is pulled .
A slingshot gains it's energy from a rubber band and the wood on the front is not used .
Crossbows release lots of energy whilst a slingshot does not .
On the other hand , a slingshot is much better for shooting lightweight stuff ( like a paper plane)
