Final answer:
A marble balanced on the head of a pin has high potential energy due to its elevated position and low kinetic energy since it is not in motion. It has the potential to convert this energy into kinetic energy if it falls.
Step-by-step explanation:
A marble that is balanced on the head of a pin has high potential energy and low kinetic energy. Potential energy is related to the position of an object and the work done against a force like gravity. Since the marble is not moving, it has no kinetic energy, which is the energy of motion. When the marble is displaced from a height, such as rolling down a pipe, its potential energy is converted into kinetic energy. If the pipe is higher, the marble has more gravitational potential energy at the start, and thus more kinetic energy when it comes out of the pipe. However, a marble on a pin is not in motion, so it does not have kinetic energy, only potential energy because of its elevated position.
