Physical Science help please difference between an electric motor and an electric generator?
I need some help with these questions
What is the primary difference between an electric motor and an electric generator?
Your friend says if you the spin the shaft of a DC motor, the motor becomes a DC generator. Do you agree or disagree? Explain your reasoning.

Answer by bdwolfhound
They are exact opposites. A motor provides output power, almost universally in terms of shaft out put RPM and torque, while a generator provides out electricity in an amount proportional to input work. Bot can be either AC or DC

    An electric motor converts electric energy into mechanical work.
    A generator converts mechanical work into electric energy.
    A DC motor being able to generate electricity depends on the construction. A brushless type can not be used for generating electricity due to the impossibility of capturing the induced voltage.
    A “normal” DC motor can however be used for generating electricity. By moving the coils into a magnetic field, electricity is induced into the coils.
