Materials:
2 meter sticks (additional meter stick may be needed if car exceeds meter sticks)
tape
friction car
Driving with Energy data sheet
Procedures:
1. Meter Reader will tape down meter sticks to floor with the meter sticks touching 0 cm to 0 cm.
2. Energy Engineer will position friction car at 0 cm and pull it back to the designated distance for trials # 1 - 4 listed in the
data chart below.
3. Data Manager will record your findings on chart.
4. For trial #5, as a group decide how far to pull back the friction car and record your findings.
