Make motion easy to understand in the world of teaching Physics.

It is commonly used to demonstrate waves in physics' experiments as well as other useful properties.

Understanding how such properties work is essential to engineers who must apply the theories and principles of science and mathematics

every day in solving practical technical problems such as harnessing the power of fuels that drive our cars, airplanes, trains, and ships;

transforming water power into electricity; using steel and concrete to build dams, roads and bridges; etc.

Our 2-inch Metal coil springs, like all objects, tend to resist change in its motion.

Because of this inertia, if placed at the top of stairs it stays at rest without moving at all.

At this point it has potential or stored energy.

But once it starts down the stairs and gravity affects it,

the potential energy is converted to the energy of motion, or kinetic energy,

and the Coil spring gracefully tumbles coil by coil down the stairs.
