MOTORIZED CART LAB

SET UP

• First gather your equipment:
• Stop watch
• Slow and fast cars
• Tape
• 3 Meter sticks

STARTING

• Then we decided the distances we wanted to the cars to travel
• We chose: 1m, 1 1/2m, 2m, 2 1/2m, 3m
• Before we started we chose to time the fast car first
• Doing a few test rounds first, we timed the fast car
• Then we recorded the findings

TIMES FOR FAST CAR

• 1m = 2.3s
• 1 1/2m= 3.7s
• 2m = 5.3s
• 2 1/2 = 6.7s
• 3m = 8.1s

TIMES FOR SLOW CAR

• 1m = 4.8s
• 1 1/2m = 8s
• 2m = 10.4s
• 2 1/2m = 12.6s
• 3m =17.1s

SLOPE

• Fast car: 1/2
• Slow car: .187

VELOCITIES

• Fast car: .383 m/s
• Slow car: .189 m/s

CONCLUSION

• By recording the times of the slow and fast cars we were able to calculate the slope
• and velocity from the graphs we made.
• FINDING the slope and velocity posed to be a problem
• But with help we found the slope and velocity of the fast car was greater than the slow car
• The fast car was .194m/s faster than the slow car, as we believed from the start
