Spring Ladder

Spring Ladder is a great introduction to conversion of energy. Spring potential energy and kinetic energy keeps changing.We have Inertia at the beginning.If you dont touch the spring it stays,but if you do its gonna keep going.

Materials: Spring and stairs

Place the spring on top of the stairs, and give it a little help for starting the motion, after it starts to motion it will keep going until it finally reaches the bottom.Inertia,potential and kinetic energy will come.Some errors might occur before the final experiment.

Behind the experiment:
linky is a helical spring that stretches and 
can bounce up and down. It can perform a number of tricks, 
including traveling down a flight of steps end-over-end as it stretches and re-forms itself with the aid of gravity and its own momentum.
