      A person walking through snow sinks into it.

      The person makes a change so that they do not sink as far next time they go out.

      What do they do?

      • Crouch as they walk to lower their centre of mass

      • Run as fast as they can to increase the power they dissipate

      • Wear shoes with a much larger area on the bottom to increase the area of their feet in contact with the snow

      • Wear a heavy backpack to increase their weight and so make them more stable .
