The students performed an investigation to determine how many spheres moved on the right when different numbers of spheres were pulled back and released from the left. The table shows the results.of the spheres? Which evidence from the students' investigation demonstrates that the pattern of motion for the spheres is predictable?

• 1. The spheres eventually stop moving.

• 1. The spheres on the left side can be pulled back.

• 1. The movement of the spheres occurs over different periods of time.

• 1. The movement of the sphere on the left matches the movement of the released spheres.

If spheres #1 & 2 are pulled back and released at the same time as spheres #4 & 5, what will be the motion of the spheres in Newton's cradle?

• All 5 spheres will begin moving in the same direction together.

• Spheres 1 & 2 will bounce back. Spheres 4 & 5 will bounce back. Sphere #3 will not move because of balanced forces.

• Spheres 1, 2, & 3 will move to the right and strike spheres 4 & 5. Then spheres 3, 4, & 5 will move to the left and strike spheres 1 & 2.

• Spheres 1 & 2 will move to the right and spheres 4 & 5 will move to the left, colliding in the middle.
