8/24 and 8/25 On-Level Chem Exit Ticket

An experiment was done to study factors that affect the rotation of a top. An electric motor was attached to a top and used to give the top a known spin rate. Once the desired spin rate was achieved, the motor was removed and the number of rotations per minute was counted. The process was repeated using different spin rates. The results are shown below. What is the independent variable?
