“…where E is the gravitational potential energy, m is the mass, g is the gravitational acceleration of Earth's surface, and h is the height of fall. Similarly, the impact characteristics of a steel ball of the same weight dropped from different heights (10,20,30,40, and 50 cm) were also tested. It can be seen from the figures that the voltage signal increases gradually with increasing height (Figure 4f), the gravitational potential energy and the impact force also increase as well (Figure 4g), and the inset shows the schematic diagram of a ball of the same weight dropped at different heights.…”
