It can be the sweetest of sounds and feelings when a driver strikes a golf ball, but it’s also brutal: A club-ball collision can produce upwards ... some of the kinetic energy in the clubhead becomes ...

One example of an elastic collision would be one billiard ball striking another. Ignoring the friction between the balls and the table or any spin imparted to the cue ball, ideally the total ...

Such deviations mean that the collision between the two CMEs must have significantly changed their propagation directions and/or speeds. For the case of two expanding elastic balls, not only will ...

Sometimes two CMEs collide and bounce off each other like elastic balls, changing their directions and speeds. It has been suggested that in some cases the collisions can even be super-elastic ...
