WGU Integrated Physical Sciences (MTC1) Integrated-Physical-Sciences Prüfungsfragen mit Lösungen
1. Ball 1 is moving and ball 2 is still. Both balls have the same mass.
What happens to the motion of the two balls if ball 1 strikes ball 2 head on in an elastic collision?
A) Ball 1 and ball 2 both move in the direction that ball 1 was initially moving, but ball 2 moves twice as fast.
B) Ball 1 stops, and ball 2 moves at the velocity ball 1 had before the collision.
C) Ball 2 remains at rest, and ball 1 moves at twice its original velocity.
D) Ball 1 and ball 2 both move in the direction that ball 1 was initially moving, but ball 1 moves twice as fast.
