Effect of object mass in coeficient of restitution

Physics Asked by SamuelNLP on January 26, 2021

I know the coefficient of restitution depends on the velocity before and after the impact of a bouncing ball. How does the mass affect it. Can’t figure it out.

formula

v is the scalar velocity of the object after impact

u is the scalar velocity of the object before impact

formula

and the H and h are related to the heights. How can I relate it to the mass of the object?

One Answer

The coefficient of restitution is defined as the ratio of relative velocities of colliding bodies before collision with relative velocity of colliding bodies after collision.

As these velocities are not dependent on the masses of the colliding bodies, the coefficient of restitution is also independent of the bodies' masses.
