2. You can try different combinations to connect the terminals of the motor like:
   • + and -
   • - and +
   • - and -
   • + and +.

Questions:

1. In which direction the motor's shaft spins in different situations?
2. In which direction the electric current flow?
3. Why does motor is not spinning when both connectors are connected to + terminal of the battery?

Summary

The rotation of the DC motor depends on the direction of electric current.

Issues

When I connect the DC motor to + and - terminals of the battery the motor's shaft does not spin.

Check the voltage of the battery… battery may be discharged.
Check the connectors of the motor… may be bad.
