Energy ConversionsEnergy Conversions

There is potential energy before tape There is potential energy before tape measure is releasedmeasure is released

Tape measure changes to kinetic energy Tape measure changes to kinetic energy as it goes down the rampas it goes down the ramp

The catcher changes from potential to The catcher changes from potential to kinetic energy as the tape measure lands kinetic energy as the tape measure lands in it, causing it to move downwardin it, causing it to move downward

The energy change in the catcher causes The energy change in the catcher causes the potential energy in the spring within the potential energy in the spring within the dart gun to convert to kinetic energy the dart gun to convert to kinetic energy and shoot the dart into the cup.and shoot the dart into the cup.
