## Mechanical Energy Calculator:

Enter the values of Mass m_{(kg}, Velocity v^{2}_{(m/s },Acceleration of gravity g_{(9.81m/s}^{2}_{)} and Height of the Object h_{(m)} to determine the value of Mechanical Energy ME_{(J)}.

**Mechanical Energy Formula:**

The Mechanical Energy ME_{(J)} in Joules is Equal to the Half into Multiply the Mass m_{(kg)} in kilogram and Multiply the Velocity v_{(m/s)} in meter per second is squared to Addition of the Mass m_{(kg)} in kilogram and is Multiply the Acceleration of gravity g_{(9.81m/s}^{2}_{)} in meter per second square and again Multiply the Height of the Object h_{(m)} in meter.

The Formula of Mechanical Energy can be written as,

ME_{(J)} = ½ * m_{(kg)} * v^{2}_{(m/s)} + m_{(kg)} * g_{(9.81m/s}^{2}_{)} * h_{(m)}

Here,

ME_{(J)} = Mechanical Energy in Joules

m_{(kg)} = Mass in kilogram

v_{(m/s)} = Velocity in meter per second

g_{(9.81m/s}^{2}_{)} = Acceleration of gravity in meter per second square

h_{(m)} = Height of the Object in meter

Mechanical Energy Calculation:

1) Calculate the Mechanical Energy and given for the Mass = 5kg , Velocity = 4m/s , Height of the Object = 4m.

Answer

ME = ½ * m * v^{2} + m * g * h

ME = ½ * 5 * 4^{2} + 5 * 9.81 * 4

ME = 236.2J.

2) Calculate the Height of the Object and given for the Mass = 5kg , Velocity = 4m/s , Mechanical Energy = 236.2J.

Answer

ME = ½ * m * v^{2} + m * g * h

236.2 = ½ * 5 * 4^{2} + 5 * 9.81 * h

h = 4m.
