On kinetic energy and potential energy on the earth

Kinetic energy and potential energy can be converted to each other. For example, standing on the 30th floor is about 100 meters. At this time, your potential energy is high, and then you jump down and land at high speed. When landing, the kinetic energy is high, and then it is deformed. If you don't consider air resistance, all your gravitational potential energy is converted into kinetic energy.
