The movement of our bodies on Earth with a gravitational force of 9.8 m/s 2 allows us to walk with our feet on the ground. float up (can be seen often in space movies) in conjunction with the work of the 3 systems above for more visual comparisons You try walking up a steep floor. may not have to be very steep Then try to observe the force that we use to walk up the steep floor whether we need to exert more energy or not. Which the answer should be the same as "yes", we have to exert more than usual walking on level ground. That's because we have to walk against the strong line of "Gravity" with a downward direction
