Non-conservative forces convert mechanical energy into other forms of energy, or convert other forms of energy into mechanical energy.

Question

Quizplus · Accepted Answer

Non-conservative forces, such as friction or air resistance, do not conserve mechanical energy and instead convert it into other forms of energy such as heat or sound. Similarly, external forces that are not conservative, such as a motor or a person pushing a cart, can convert electrical or chemical energy into mechanical energy.
