What is the formula of potential energy and mechanical energy?
The potential energy of an object is zero when it is in the movement and kinetic energy is zero when the object is in rest. The formula of mechanical energy is M.E = K. E + P.E M.E = mv2 + mgh
What is mechanical energy in physics?
Mechanical energy can also be defined as the energy of an element due to its position or motion or both. The potential energy of an object is due to its position and kinetic energy is due to its motion. The potential energy of an object is zero when it is in the movement and kinetic energy is zero when the object is in rest.
How do you find the mechanical energy of an object?
If K E and P E refers to the kinetic and potential energies of a body, its mechanical energy is given by, Where,m is the mass of an object, v , the velocity of that object, g, the acceleration due to gravity and h tells at what height the object is from the ground.
How do you write the mechanical energy equation for a turbine?
The mechanical energy equation for a turbine – where power is produced – can be written as: pin / 蟻 + vin2 / 2 + g hin = pout / 蟻 + vout2 / 2 + g hout + Eshaft + Eloss (2)
