Question

a bird has kinetic energy of 3 J and potential energy of 25 J what is the mechanical energy of the bird

Answer 1

28 J, because mechanical energy is the sum of the potential energy and kinetic energy

Explanation:

Answer 2

Mechanical Energy is the sum total of potential and kinetic energy. Potential energy is possessed due to its position, whereas kinetic energy is possessed due to the movement of the object. We calculate the mechanical energy as follows:

ME = KE + PE
ME = 3 J + 25 J
ME = 28 J
