from the kinetic store of the trolley to the elastic potential store of the spring
from the thermal store of the spring to the kinetic store of the trolley
from the gravitational potential store of the spring to the kinetic store of the trolley
from the elastic potential store of the spring to the kinetic store of the trolley
