Short summary
General laws regarding the effect of the impact angle on the coefficients of restitution occur regardless of the test scales and conditions. Increasing the impact angle results in a reduction of Rn, Rv and RE and causes an increase in Rt. The rotation plays an important role in the effect of the impact angle. A higher percentage of kinetic energy converted to rotational energy always induces a higher Rn and a lower Rt. The percentage can be associated with the impact angle and the rock sizes.
