1. FALSE Elastic potential energy stored by a spring. The potential energy stored in a spring (or any similar object) is known as the elastic potential energy. It is stored by the deformation of an elastic material such as the spring seen in Figure 1.
2. TRUE As already mentioned, the mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.
3. TRUE make sure you have disconnected power source from any electric-powered equipment before starting maintenance work.
4. TRUE The mechanical energy of a free-falling body always remains to conserve during a free fall.
5. FALSE As an object falls under the influence of gravity, kinetic energy and potential energy are equal everywhere/at the halfway point only.
