Why did the Shock Absorbers Model Selection Software recommend selecting a larger RB series shock absorber for lower collision speeds than for higher collision speeds?

The corresponding mass (Me)＝, which serves as a criterion for the judgment, becomes larger when the collision speed v becomes slower, and the corresponding mass becomes larger when the same energy is used.
The corresponding mass is also called the corresponding mass of the impacting object.
① (Unit of collision speed v: m/s) Me becomes larger when the speed becomes less than 1 m/s because the square of the speed is the denominator.
② Back pressure is generated in the shock absorber because the volume is compressed as the oil passes through the orifice, and the back pressure of the oil is shock absorbed as drag.
When the speed is slow, the oil volume is weakly compressed, so the drag generated also decreases. Due to ① and ②, a larger-sized shock absorber is recommended in order to compensate.
