This is what scientists call Newton's cradle. It is a handy devise used to illustrate many concepts in physics. Imagine the ball on the right is dropped. According to Newton's third law of motion, what is the expected result once the ball
hits the ball closest to it?
0) Q:
A:
A)
The single ball on the left will move as high as the ball on the right was
dropped.
The dropped ball will exert a force on the first ball it hits and that ball will
move slightly.
B)
9
The second ball will move to the right causing a chain reaction and all
four balls will then move right.
X D)
The second ball in the line will exert and equal force on the dropped ball
and both balls will stop moving.
