Which Is A True StateMent?
When comparing the force that is required to climb a mountain by walking up a trail that slopes gently upward to the top, versus getting there by scaling asheer vertical cliff face, """"I believe it would be D""""

a. You use more force gor a given distance of movement on the walk than on the climb
b. Walking up the trail forces you to cover a greater distance but the amount of force needed to cover a given distance will be less
C. Scaling the vertical cliff while dangerous uses less force than going the "gentler" way around
D. The distance covered is the same either way but scaling the cliff is harder cause you are working against gravity

  1. Are you sure the distance covered is the same? Think of a right triangle. Which is longer -- the hypotenuse of the vertical line?
