Understanding Newton's Third Law

I don't know why , but if one day I am not sharing you about #physics I feel that my task is not complete . Although , I am in week of exam I promise you all I will try to divide my time to share you all about #physics .

What we want to talk today ? Hmm , lets we find something simple that we do everyday and related to physics . Walking ! Ya Walking . You know that when you walk there number of principles of physics are involved such

Weight , Newton's Three( Law of Inertia) ,Gravitational and Potential Law also the Kinetic energy .

For your information , when you walk your foot act like an inverted pendulum .

When your foot on the floor, it will be our axis and our weight is center at our abs its is decribing an arc shape.

And also when our foot on the floor, we actually put the weight , w=mg and we're applying backward force on the floor , as a respond on our body weight , the ground will response as a opposite force and it's vertical .

When your leg moving , the kinetic energy will be maximum and the potential energy is zero ,but when you foot is nearest your belly , the potential energy will became maximum,

When you take another step ,the potential energy that stored will be change to the kinetic energy and this process are continuing if you keep walking

We are acting as an imperfect pendulum , because the potential energy is not use completely , our body contain around 60% of potential energy to take the another step and the others 40% as our body biochemical process .

Sir Isaac Newton
Okay , when we walk we are doing some work in physical term , such W = FS, when we're using some force we're cover some distance when are doing a work .

When walking Newton's Third, Law of motion applied . First law of motion says states that, our body will remains in state of rest unless a force is applied on our body . Inertia is at maximum, when we're rest. To get out state of the inertia our body needs largest amount of force

For instance when you start walking we start moving and you take the first step your energy is transferred from foot to upper body parts , during this process the inertia will increases when we set foot on ground and vice versa.

Second law of motion states that the acceleration is directly proportional to the force that we use while walking , when more fore we applied , the acceleration will incease too .

Action and reaction is in third law of motion , when we our foot on ground we will bring force on it and as a result to it ground bring reactionary to vertical force on our body.

Now we know that , when we walk there some physics principle will be applied . So if you want to walk quickly you need to increase your force to increase the acceleration . Here is the explaination video to make you more understand .

So , now we know that whatever we do , activities ,works and so on . It's related to #physics .
