In walking, the potential energy is highest at mid-stance while the kinetic energy is lowest. The potential and kinetic energies are out of phase, swapping off through each step. During running, the energies are in phase working together to propel the body into double float.

here. We have been given an example that a person is eating the breakfast and then going for Redden. Now, according to this example, we have to answer a few questions. Yeah. The first question is asking us to give up chemical equation to explain the energetic process which is going on in the example given to us. So the chemical equation here which would act is C 12 H 22 0 11, that's the same amount of water. They don't give C6 H 1246 less C six H 12 or six and some amount of heat. This is the chemical equation for the example which is given to us Now, talking about the second question, it is asking us that in the given example we have to define a situation where potential energy plays its role. So potential energy defines director energy which is really stalled. So yes, we can see that the food which is eaten by that person gets converted into You can meet them energy with the help of chemicals which act on that fourth during the process of fertilization. Now, after the process of decision is completed, this food gets stored in our body and this food after the completion of the whole process this storage results into the for 10 Children energy and these books can then withdraw as the potential energy of the body. Next We have been asked that in the given example where is the kinetic energy which has been acted. So we know that kinetic energy is the energy which applies on any kind of movement. So here we have been given that after eating the breakfast, that person went for the running this johnny is the process off utilizing this toad potential energy and converting it into kinetic energy. This was an option for the 3rd point of the question. Now, both part of the question is asking us that this example is related to the first love of there's more dynamics. So we know that in the first law of thermodynamics, this stated to us that the total N. L. G. Of any kind of work of the whole universe, we can say that its total energy the means constant. So here or two, we can see that the chemical energy which was produced by the digitization of wood, these converted into potential energy due to the storage of food and its nutrient in our body. Then these potential energy. What we didn't do kinetic energy patterns, the person went for johnny and the movement of body took place which resulted in kinetic energy. So the energy which was being provided to that person remained constant and it just moved around with the different me and in the different processes. But that energy is going nowhere else that it is not being either destroyed or new energy is not produced. They are just being Moving from one place to another. And the last question is asking us that how this example is good for second law of there are more dynamics. So second law of thermodynamics says that its main concern is regarding the direction of natural processes are natural movement. It assists that the natural processes which are occurring. They are moving in one particular direction, and they are not diverged. Seven. So here also we can see that the energy God confided from chemical to potential, and then to the kinetic energy. In other words, we can say that the food which was eaten what converted our court digested and then it was utilized for Ronnie. And he is the reversal that is after running the food again, getting back to its duty version stomach. This process does not take place. So we can say that there is only a one way direction of this movement of energy and there is no diversity employees is project. It only gets renewed in tisa marty, a death process.
