I need an urgent explanation

[vidid2all]

is there any form of energy that is release when we walk on a surface ie; this form of energy is absorb by the surface of the material . eg walking on a ground, driving a car or riding a bicycle.

friction which will involve heat. If you have an infrared camera you can see the heat of each footstep.

[Delta1212]

Sure. Kinetic energy from footfalls, heat energy from friction.

<<​and + the momentum of your body falling constantly.

Gosh what a jumbled up question.

 

Is this homework or a test that you require such an urgent answer you have to leave before anyone can answer?

 

It certainly does not belong in modern and theoretical physics.

 

OK so release of energy when you walk, and presumably when travel by the other means stated as well.

 

Released is not really the correct term but we can discuss this if you ever return.

 

Conservation of energy requires that energy is generated somewhere during the activity and transferred to the support surface, by work being done on the support surface (mechanical energy transfer) or by temperature difference between the traveller and the support surface (heat energy transfer).

 

Friction will only do work if there is slippage or sideways movement between the contact surfaces.

 

Work is done in deforming both contact surfaces and transferred to the support surface as strain energy.

 

You have not offered the examples of cutting or grinding tools, but work will also be done in cleaving the support material.

 

Finally, as delta1212 observes, impact work will be done if there is impact rather than smooth rolling.

 

Momentum is not work or energy.

Hello

 

Other way ... If you are on a raft on water plan ,and walking to the right , the raft will go to the left .

 

If all the humanity walk to the west ,animals , even more , what will happened to the earth rotation ?

It will speed up a tiny amount. Then, when they stop, it will slow down again. The earth has a rather large moment of inertia.

[slan11]

Tides works on negative to the rotation ... day after day , if this is cumulative , why not additive .

 

Energy : A mass on a foot step .... a mass on a two foot step is egual to a double mass on a foot step . Nothing lost .

 

Additive energy to the earth foot after foot . May be we must have a sufficient report of mass .

 

Somes earhquakes move poles position .

The Momentum of the falling body is = to the friction fores with the surface being walked on ,,,other wise your're not walking

Each time you push a mass ahead ... you push a egual mass/speed backward .
