When is elastic potential energy stored and when is it released in: a toy glider launcher the elastic cords or springs beneath a sun-lounger a diving board?

Explanation:

Assuming a toy glider works on a spring potential energy is stored when the spring(launcher) is fully compressed..and is released when the spring is released.

Potential Energy is stored when the diver has stepped on the board, and the board is at the bottom of its movement, and is released when the diver jumps off.

explanation:

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
