Increase in Gravity?

  1. May 4, 2008 #1
    If gravity on earth were to increase overnight by 10% how do I go about calculating the way this would affect my movements, how fast I could walk, run, swim etc and how this would affect my muscles? I'm presuming my body would be working harder so I would find movement more tiring and would be slower but could do with being able to demonstrate this? would really appreciate any guidance to the calculations I would need to make?

    Many thanks

    What, exactly, is it that you want to calculate? If g is increased by 10% then the work (mgh) necessary to lift a weight, take a step (which involves both raising your feet and raising your center of gravity), raise your arms, etc. would require 10% more work.
