Can mechanical energy change
WebNov 8, 2024 · Other transfers of energy can happen between mechanical energies, like ball being throw upward or dropped down (assuming effects of air friction are negligible). … WebDec 30, 2016 · Explanation: Mechanical energy is the sum of kinetic and potential energy in a system. Emech = K + U Mechanical energy is conserved so long as we ignore air resistance, friction, etc. When we don't ignore outside forces, such as those just mentioned, mechanical energy is not conserved.
