The Lazy Flag Raiser Our device takes advantage of spring energy and gravitational potential energy to complete its task. The task is a unique way to raise a flag.
Energy Conversions Potential Spring Energy -> Kinetic Energy From the release of the spring, energy is transferred to the ball Kinetic Energy -> Gravitational Potential Energy The ball is projected up a ramp to a stop Gravitational Potential Energy -> Kinetic Energy The cup and ball system converts its potential energy to kinetic
Conclusions Successful? Yes Learned the application of the concepts from the previous modules to actual real life scenarios Don’t touch hot glue Problems? Hot glue not adhering to surfaces and stability Do Differently: Plan ahead more.
