  • Energy expenditure

    v1 v2  
    1111                                    h : profondeur 
    1212                                    S : pente 
    13 As energy is 1/2mv² the energy is related to altitude. With potential energy mgh it also makes sense, but we should add them not multiply... 
     13The additional energy due to slope is related to the current 
     14distance additional=v*t 
     15~c(hS)1/2*t 
     16~alpha t (E/D)1/2 with alpha a multiplying coeff depending on depth, C 
     17t is proportional to the distance 
     18so beta(DE)1/2 
    1419 
     20Energy=D+sqrt(DE)
