its force and speed and energy
It is a device that can store elastic energy. It is not a machine, which changes force and distance and/or direction.
It is an effort machine
A simple machine is a type of machine that changes forces in some way, by amplifying them, and/or changing their direction. The lever, the pulley, the wheel and axle are all simple machines. But there are complex machines as well, which do far more things. Our computers are also machines.
