Design Overview Golf ball ramp Barrier Golf cart track Funnel barrier Funnel and sand Bucket and pulley

Stored Energy Overview Golf ball on ramp PE = (0.046 kg)(9.81 m/s²)(0.27 m) = 0.122 J Golf cart on track KE = ½(0.063 kg)(0.628 m/s)² = 0.0124 J Sand falling through funnel PE = (0.341 kg)(9.81 m/s²)(1.00 m) = 3.35 J

Design/Construction Issues Golf cart ran off track Golf cart stuck to railing Golf cart did not move funnel barrier Golf ball missed barrier Solutions Put up railing Removed railing and sanded down track Clamped down supports and stiffened funnel barrier Moved barrier further away from track

Conclusions Potential energy can be converted to kinetic energy to do work. Friction hampers conversion of potential to kinetic energy. Loose components can cause energy loss. Efficiency can be improved by making collisions more elastic.
