Answer:
Mechanical energy is the sum of kinetic energy and potential energy
Step-by-step explanation:
Mechanical energy is the sum of kinetic energy and potential energy. Mathematically, it is equal to :
ME = KE + PE
Where
KE = kinetic energy
PE = potential energy
m = mass of an object
g = gravity
h = height above ground level
Mechanical energy is possessed due to the motion of an object and its position. Motion of an object is given by the kinetic energy and the energy possessed due to its position is given by its potential energy.
Hence, mechanical energy is the sum of kinetic energy and potential energy.
