Identify forms of potential energy. |
Potential energy is the energy an object has because of its position or shape. So, for example, an object’s gravitational potential energy changes when it moves through a gravitational field.An object may have elastic potential energy when it is stretched, squashed or twisted–if it is released it goes back to its original shapeAn electrically charged object has electric potential energy when it is placed in an electric field.
