Hello there.
What does an Electric Motor do?
Answer: Converts electrical energy into mechanical energy.
If the object is moving in a straight line with constant speed,
that's a description of " acceleration = zero ".
Zero acceleration means zero net force on the object.
NO net force is 'required' to keep an object moving in a straight line
at constant speed. In fact, if there IS any net force on the object,
then either its speed or its direction MUST change ... there's no way
to avoid it.
None of this depends on the object's mass, or on the speed or direction
of its motion.
Weight is the measurement of the pull of gravity on an object, while mass is the measurement of the amount of matter that an object contains.
