Quizplus · Accepted Answer

Animals must overcome both friction and gravity to move. Gravity pulls them towards the Earth, requiring effort to lift or move the body, while friction can either impede or assist movement depending on the context. Inertia, the resistance to changes in motion, is a factor in movement but not a force to be overcome in the same sense as friction and gravity.
