Ball size, crater diameter and impact energies |

| Table 2 - crater diameters and calculated impact energies. Errors are shown for the crater diameters only, since the mass and calculated impact energies are more accurate. The kinetic energy was calculated at the surface of the sand, assuming that all gravitational potential was converted to kinetic energy, and that any additional PE release due to the penetration of the ball into the sand was negligable. |
