Answer 2

Answer:

We ae able to walk on a floor due to the gravitational force.

Explanation:

During walking on Earth, at 1.0 g of gravity, the work done by the muscles to maintain the motion of the centre of mass of the body (Wext) is reduced by a pendulum-like exchange between gravitational potential energy and kinetic energy. ... The range of walking speeds is probably greater than that on Earth.
