Potential and Kinetic Energy

The diagram shows a child on a swing. The child is swinging back and forth between points X and Z, through point Y. Points X and Z are at the same height. Which of the following statements best describes the kinetic energy and the gravitational potential energy of the child?

• The child has no potential energy and no kinetic energy at position X and position Y.

• The child has the same kinetic energy and potential energy at position X and position Y.

• The child has more potential energy and less kinetic energy at position X than at position Y.

• The child has more kinetic energy and less potential energy at position X than at position Y.
