State the parts of an electric
motor and how a motor works.

Explanation:

The main parts of an electric motor include the stator and rotor, a series of gears or belts, and bearings to reduce friction. DC motors also need a commutator to reverse current direction and keep the motor spinning. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

be subject to a force andchange its motion
