Energy Loss Calculator, Formula, Energy Loss Calculation

Energy Loss Calculator:

Enter the values of Mass of the Object M_(kg) , Initial Velocity Vi_(m/s) & Final Velocity Vf_(m/s) to determine the value of Energy Loss EL_(J) .

Energy Loss Formula:

The Energy Loss EL_(J) in Joules is Equal to the Half into Multiply the Mass of the Object M_(kg) in kilogram and multiply the Initial Velocity Vi_(m/s) in meter per second is squared and is Subtracted by the Half into Multiply the Mass of the Object M_(kg) in kilogram and multiply the Final Velocity Vf_(m/s) in meter per second is squared.

The Formula of Energy Loss can be written as,

EL_(J) = 1/2 * M_(kg) * Vi²_(m/s) – 1/2 * M_(kg) * Vf²_(m/s)

Here,

EL_(J) = Energy Loss in Joules

M_(kg) = Mass of the Object in kilogram

Vi_(m/s) = Initial Velocity in meter per second

Vf_(m/s) = Final Velocity in meter per second

Energy Loss Calculation :

1)Calculate the Energy Loss and given for the Mass of the Object = 8kg , Initial Velocity = 10m/s , Final Velocity = 5m/s.

Answer

EL = 1/2 * M * Vi² – 1/2 * M * Vf²

EL = 1/2 * 8 * 10² – 1/2 * 8 * 5²

EL = 300J.

2)Calculate the Final Velocity and given for the Mass of the Object = 8kg , Initial Velocity = 10m/s , Energy Loss = 300J.

Answer

EL = 1/2 * M * Vi² – 1/2 * M * Vf²

300 = 1/2 * 8 * 10² – 1/2 * 8 * Vf²

Vf = 5m/s.
