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

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

4. 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

5. 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.
