Potential energy is stored energy. Kinetic energy involves movement.
If a ball is on the top of a hill, it has the most potential energy on the very top of the hill. The kinetic energy is also 0 at this point.
If the ball rolls down the hill, potential energy decreases while kinetic increases.

The simple machines are the operations that allows the easy in the completion of work. The Julian toes to reach book act as fulcrum.
<h3>How do simple machine works?</h3>
The operation of work done is performed with the completion of task after the application of force. The force act at different parts of the simple machine allows the ease in the work done.
The toes of Juliana in reaching to the book allows her to apply force to them, and they help to leverage Juliana weight to the height. The mechanism is being carried by a simple machine fulcrum.
Thus, the toes of Juliana act as fulcrum by helping her in reaching to the book.
