PEstep ≈ 0.12 m x 9.81 m/s2 x 73 kg = 85.9 J/step
This implies that about 1/2 of the mechanical energy required to lift your body during one
step is lost (dissipated) when walking (friction, muscle efficacy, etc).
when you are going up a hill by walking you are converting your potential energy into kinetic energy with every step and also storing more and more potential energy with every step if you stop after every step but if you are walking with a certain velocity you possess kinetic energy . At the top of the hill when you stop you possess maximum potential energy.

The potential step is the barrier for particles to enter in to some region ,for example ,consider an electron with incident energy greater than the potential energy of an atoms ,will easily penetrate in to the atom an will comes out with some net changes in its energy and wave function , On other hand the electron having smaller energy than the potential of atom can not penetrates in to the atom ,it will bounces back from the atom , so here the neutral atom behaves as a potential step (barrier) BY SAMI UL HAQ IIUI , DEPARTMENT OF PHYSICS (NANO TECHNOLOGY ) MOB 00923038400484 SAMI786NANOTECH@GMAIL.COM
what is step and touch potential?
to identify all potential hazards associated with each step, including hazards directly connected with the job and equipment, and those potential environmental hazards

What is the term for each step in the transfer of energy and matter within a biological community?
Ten percent of the energy in each trophic level makes it to the next level.
Jesus!
Some energy is lost at each level since not all energy is transferred from the food to the consumer.
