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 go up a hill, you are converting potential energy into kinetic energy. As you climb higher, you store potential energy due to your increased height above the ground. This potential energy is then converted into kinetic energy as you descend the hill.

involve some loss of energy due to inefficiencies and natural limitations, such as the second law of thermodynamics. This loss is typically released as waste heat, reducing the overall efficiency of the process. As a result, no energy conversion process can be 100% efficient.
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?
As you move up the energy pyramid from trophic level to trophic level, around 10% of the energy is transferred from one level to the next. This means that only 10% of the energy is available to the next trophic level, with the remaining 90% being lost as heat or used by the organism for its own metabolism.
Jesus!
Some energy is lost at each level since not all energy is transferred from the food to the consumer.
