Title: The Law of Conservation of Energy

4. Release the marble on the ramp at 15 cm. Then record below what happens to the speed of both marbles after they collide.

6. Release the marble on the ramp at 15 cm. Then record below what happens to the speed of both marbles after they collide

8) Release the large marble on the ramp at 15 cm. Then record below what happens to the speed of both marbles after they collide.

10) Release the smaller marble on the ramp at 28 cm. Then record below what happens to the speed of both marbles after they collide.
