I Energy consumption for n times x/n mass function?

  1. Mar 11, 2017 #1
    Or simpler:
    Do multiple smaller objects consume more energy to move than one larger (same mass)?
    And is there a known ratio/function?

    Thanks

    Newton's second law says f=ma. So what do you think the answer is?

    Thanks for the answer.

    Can i safely transfer that into a fact that a x-kg car has same fuel consumption as two x/2-kg cars? Or is that an engineering question?

    No.. Cars are dominated by friction. They use gas even when not moving no matter what they weigh. They have four tires no matter what they way.

    For cars, simple physics is not enough, it is an engineering question.

    Wanted to check some basics first.

    Thanks :)
