REFLECTION 1. Did the theoretical mass from the balance fall within the error bars of the experimental mass? If not, do you think your percent error is “close enough”? 2. Think back to your experimental method. Is there any systemic problem in our apparatus that
might have contributed an invisible force that wasn’t counted by the sensor?
3. You probably had plots similar to those to the right for the cart’s run down the track. Offer an
